I receive Text File that I have to Import to a SQL Table, I have to come with a SSIS because I will received the Flat File every Day , with the First Row as the Customer_ID, then come the invoice details and then the Total of the invoice.
Example :
30303
0000109291700080190432737000005Name of the product
0000210291700080190432737000010Name of the product
0000309291700080190432737000000Name of the product
003 000145
So let me Explain:
First 30303 is the Customer #
Other Rows Invoice Details
00001-> ROWID 092917-> DATE 000801904327->PROD 370->Trans 00010 -> AMOUNT
Name of the product
Last Row
003==>Total rows 000145==>Total of Invoice
Any Clue ?
I would use a Script Component as a source in a Data Flow Task. You can then use C# or VB.net to read the file, e.g., by using System.IO.StreamReader, in any way you wish. You can read a line at a time, store values in variables to write to every row (e.g., the customer number), etc. It's extremely flexible for complex files.
Here is an example script (C#) based on your data:
public override void CreateNewOutputRows()
{
System.IO.StreamReader reader = null;
try
{
bool line1Read = false;
int customerNumber = 0;
reader = new System.IO.StreamReader(Variables.FilePath); // this refers to a package variable that contains the file path
while (!reader.EndOfStream)
{
string line = reader.ReadLine();
if (!line1Read)
{
customerNumber = Convert.ToInt32(line);
line1Read = true;
}
else if (!reader.EndOfStream)
{
Output0Buffer.AddRow();
Output0Buffer.CustomerNumber = customerNumber;
Output0Buffer.RowID = Convert.ToInt32(line.Substring(0, 5));
Output0Buffer.Date = DateTime.ParseExact(line.Substring(5, 6), "MMddyy", System.Globalization.CultureInfo.CurrentCulture);
Output0Buffer.Prod = line.Substring(11, 12);
Output0Buffer.Trans = Convert.ToInt32(line.Substring(23, 3));
Output0Buffer.Amount = Convert.ToInt32(line.Substring(26, 5));
Output0Buffer.ProductName = line.Substring(31);
}
}
}
catch
{
if (reader != null)
{
reader.Close();
reader.Dispose();
}
throw;
}
}
The columns in 'Output 0' of the Script Component are configured as follows:
Name DataType Length
==== ======== ======
CustomerNumber four-byte signed integer [DT_I4]
RowID four-byte signed integer [DT_I4]
Date database date [DT_DBDATE]
Prod string [DT_STR] 12
Trans four-byte signed integer [DT_I4]
Amount four-byte signed integer [DT_I4]
ProductName string [DT_STR] 255
To implement this:
Create a string variable called 'FilePath' with your file path in it for the script to reference.
Create a Data Flow Task.
Add a Script Component to the Data Flow Task - you'll be asked what type it should be, select 'Source'.
Right-click the Script Component, click 'Edit'.
On the 'Script' pane, add the 'FilePath' variable to the 'ReadOnlyVariables' section.
On the 'Inputs and Outputs' pane, expand 'Output 0' and add columns to the 'Output Columns' section as per the above table.
On the 'Script' pane, click 'Edit Script', and then paste my code over the public override void CreateNewOutputRows() method (replacing it).
Your Script Component source is now configured, and you'll be able to use it like any other data source component. To write this data to a SQL Server table, add an OLEDB Destination to the Data Flow Task, and link the Script Component to that, configuring the columns appropriately.
I have built an SSIS package that loads in several delimited text files into a SQL database. One of the files often contains line spaces in it, which breaks the standard data flow task of setting a flat file source and mapping to an ado.net destination since it thinks it is on a new line when it reaches a line break. The vendor sending over the files does not want to sent the file without any edits and can't do XML at this time. Is there any way to fix this? I was thinking of writing a small vb.net program that would correct the files so they would work in the SSIS package, but not sure how to write that logic. The file has 5 columns, the first 2 are big integer and always contain some long integer ID, then there is a small text column that just contains one short word, then a date, and then a long comments field that is causing the problem. The comments field is sometimes blank (which is ok), the problem are the rows that have line breaks. I never know how many line breaks are in the comments, some have none, some can have several, even multiple line breaks in a row, so was wondering if this is even possible.

Sample File Format.
As long as there is logic that you can program/predict, it will be possible.
I would do it using a Script Component as a source, which means you don't need to rewrite the file before processing it. It also provides a lot of flexibility, e.g., you can store values in variables while iterating over multiple lines in the file, etc.
I posted another answer recently that gives a lot of detail on how to go about this: SSIS import a Flat File to SQL with the first row as header and last row as a total.
An example of holding the values in variables until the row is ready to be written:-
For this example I am writing three columns, ID1, ID2 and Comments. The file looks like this:
1|2|Comment1
Comment2
4|5|Comment3
Comment4
Comment5
6|7|Comment6
The Script Component contains the following method.
public override void CreateNewOutputRows()
{
System.IO.StreamReader reader = null;
try
{
bool readFirstLine = false;
int id1 = 0;
int id2 = 0;
string comments = null;
reader = new System.IO.StreamReader(Variables.FilePath); // this refers to a package variable that contains the file path
while (!reader.EndOfStream)
{
string line = reader.ReadLine();
if (line.Contains("|"))
{
if (readFirstLine)
{
Output0Buffer.AddRow();
Output0Buffer.ID1 = id1;
Output0Buffer.ID2 = id2;
Output0Buffer.Comments = comments;
}
else
{
readFirstLine = true;
}
string[] fields = line.Split('|');
id1 = Convert.ToInt32(fields[0]);
id2 = Convert.ToInt32(fields[1]);
comments = fields[2];
}
else
{
comments += " " + line;
}
if (reader.EndOfStream)
{
Output0Buffer.AddRow();
Output0Buffer.ID1 = id1;
Output0Buffer.ID2 = id2;
Output0Buffer.Comments = comments;
}
}
}
catch
{
if (reader != null)
{
reader.Close();
reader.Dispose();
}
throw;
}
}
The result set is:
ID1 ID2 Comments

I am wondering how to insert an image on one of the fields in my postgresql table. I cannot find an appropriate tutorial re this matter. The dataype of the field is oid. Has anyone tried this? Thanks!
// All LargeObject API calls must be within a transaction
conn.setAutoCommit(false);
// Get the Large Object Manager to perform operations with
LargeObjectManager lobj = ((org.postgresql.PGConnection)conn).getLargeObjectAPI();
//create a new large object
int oid = lobj.create(LargeObjectManager.READ | LargeObjectManager.WRITE);
//open the large object for write
LargeObject obj = lobj.open(oid, LargeObjectManager.WRITE);
// Now open the file
File file = new File("myimage.gif");
FileInputStream fis = new FileInputStream(file);
// copy the data from the file to the large object
byte buf[] = new byte[2048];
int s, tl = 0;
while ((s = fis.read(buf, 0, 2048)) > 0)
{
obj.write(buf, 0, s);
tl += s;
}
// Close the large object
obj.close();
//Now insert the row into imagesLO
PreparedStatement ps = conn.prepareStatement("INSERT INTO imagesLO VALUES (?, ?)");
ps.setString(1, file.getName());
ps.setInt(2, oid);
ps.executeUpdate();
ps.close();
fis.close();
Found that sample code from here. Really very good bunch of sql operations.
To quote this site,
PostgreSQL database has a special data type to store binary data
called bytea. This is a non-standard data type. The standard data type
in databases is BLOB.
You need to write a client to read the image file, for example
File img = new File("woman.jpg");
fin = new FileInputStream(img);
con = DriverManager.getConnection(url, user, password);
pst = con.prepareStatement("INSERT INTO images(data) VALUES(?)");
pst.setBinaryStream(1, fin, (int) img.length());
pst.executeUpdate();
You can either use the bytea type or the large objects facility. However note that depending on your use case it might not be a good idea to put your images in the DB because of additional load it may put on the DB server.
Rereading your question I notice you mentioned you have a field of type oid. If this is an application you are modifying it suggests to me it is using large objects. These objects get an oid which you then need to store in another table to keep track of them.
I am running data.bat file with the following lines:
Rem Tis batch file will populate tables
cd\program files\Microsoft SQL Server\MSSQL
osql -U sa -P Password -d MyBusiness -i c:\data.sql
The contents of the data.sql file is:
insert Customers
(CustomerID, CompanyName, Phone)
Values('101','Southwinds','19126602729')
There are 8 more similar lines for adding records.
When I run this with start > run > cmd > c:\data.bat, I get this error message:
1>2>3>4>5>....<1 row affected>
Msg 8152, Level 16, State 4, Server SP1001, Line 1
string or binary data would be truncated.
<1 row affected>
<1 row affected>
<1 row affected>
<1 row affected>
<1 row affected>
<1 row affected>
Also, I am a newbie obviously, but what do Level #, and state # mean, and how do I look up error messages such as the one above: 8152?
From #gmmastros's answer
Whenever you see the message....
string or binary data would be truncated
Think to yourself... The field is NOT big enough to hold my data.
Check the table structure for the customers table. I think you'll find that the length of one or more fields is NOT big enough to hold the data you are trying to insert. For example, if the Phone field is a varchar(8) field, and you try to put 11 characters in to it, you will get this error.
I had this issue although data length was shorter than the field length.
It turned out that the problem was having another log table (for audit trail), filled by a trigger on the main table, where the column size also had to be changed.
In one of the INSERT statements you are attempting to insert a too long string into a string (varchar or nvarchar) column.
If it's not obvious which INSERT is the offender by a mere look at the script, you could count the <1 row affected> lines that occur before the error message. The obtained number plus one gives you the statement number. In your case it seems to be the second INSERT that produces the error.
Just want to contribute with additional information: I had the same issue and it was because of the field wasn't big enough for the incoming data and this thread helped me to solve it (the top answer clarifies it all).
BUT it is very important to know what are the possible reasons that may cause it.
In my case i was creating the table with a field like this:
Select '' as Period, * From Transactions Into #NewTable
Therefore the field "Period" had a length of Zero and causing the Insert operations to fail. I changed it to "XXXXXX" that is the length of the incoming data and it now worked properly (because field now had a lentgh of 6).
I hope this help anyone with same issue :)
Some of your data cannot fit into your database column (small). It is not easy to find what is wrong. If you use C# and Linq2Sql, you can list the field which would be truncated:
First create helper class:
public class SqlTruncationExceptionWithDetails : ArgumentOutOfRangeException
{
public SqlTruncationExceptionWithDetails(System.Data.SqlClient.SqlException inner, DataContext context)
: base(inner.Message + " " + GetSqlTruncationExceptionWithDetailsString(context))
{
}
/// <summary>
/// PArt of code from following link
/// http://stackoverflow.com/questions/3666954/string-or-binary-data-would-be-truncated-linq-exception-cant-find-which-fiel
/// </summary>
/// <param name="context"></param>
/// <returns></returns>
static string GetSqlTruncationExceptionWithDetailsString(DataContext context)
{
StringBuilder sb = new StringBuilder();
foreach (object update in context.GetChangeSet().Updates)
{
FindLongStrings(update, sb);
}
foreach (object insert in context.GetChangeSet().Inserts)
{
FindLongStrings(insert, sb);
}
return sb.ToString();
}
public static void FindLongStrings(object testObject, StringBuilder sb)
{
foreach (var propInfo in testObject.GetType().GetProperties())
{
foreach (System.Data.Linq.Mapping.ColumnAttribute attribute in propInfo.GetCustomAttributes(typeof(System.Data.Linq.Mapping.ColumnAttribute), true))
{
if (attribute.DbType.ToLower().Contains("varchar"))
{
string dbType = attribute.DbType.ToLower();
int numberStartIndex = dbType.IndexOf("varchar(") + 8;
int numberEndIndex = dbType.IndexOf(")", numberStartIndex);
string lengthString = dbType.Substring(numberStartIndex, (numberEndIndex - numberStartIndex));
int maxLength = 0;
int.TryParse(lengthString, out maxLength);
string currentValue = (string)propInfo.GetValue(testObject, null);
if (!string.IsNullOrEmpty(currentValue) && maxLength != 0 && currentValue.Length > maxLength)
{
//string is too long
sb.AppendLine(testObject.GetType().Name + "." + propInfo.Name + " " + currentValue + " Max: " + maxLength);
}
}
}
}
}
}
Then prepare the wrapper for SubmitChanges:
public static class DataContextExtensions
{
public static void SubmitChangesWithDetailException(this DataContext dataContext)
{
//http://stackoverflow.com/questions/3666954/string-or-binary-data-would-be-truncated-linq-exception-cant-find-which-fiel
try
{
//this can failed on data truncation
dataContext.SubmitChanges();
}
catch (SqlException sqlException) //when (sqlException.Message == "String or binary data would be truncated.")
{
if (sqlException.Message == "String or binary data would be truncated.") //only for EN windows - if you are running different window language, invoke the sqlException.getMessage on thread with EN culture
throw new SqlTruncationExceptionWithDetails(sqlException, dataContext);
else
throw;
}
}
}
Prepare global exception handler and log truncation details:
protected void Application_Error(object sender, EventArgs e)
{
Exception ex = Server.GetLastError();
string message = ex.Message;
//TODO - log to file
}
Finally use the code:
Datamodel.SubmitChangesWithDetailException();
Another situation in which you can get this error is the following:
I had the same error and the reason was that in an INSERT statement that received data from an UNION, the order of the columns was different from the original table. If you change the order in #table3 to a, b, c, you will fix the error.
select a, b, c into #table1
from #table0
insert into #table1
select a, b, c from #table2
union
select a, c, b from #table3
on sql server you can use SET ANSI_WARNINGS OFF like this:
using (SqlConnection conn = new SqlConnection("Data Source=XRAYGOAT\\SQLEXPRESS;Initial Catalog='Healthy Care';Integrated Security=True"))
{
conn.Open();
using (var trans = conn.BeginTransaction())
{
try
{
using cmd = new SqlCommand("", conn, trans))
{
cmd.CommandText = "SET ANSI_WARNINGS OFF";
cmd.ExecuteNonQuery();
cmd.CommandText = "YOUR INSERT HERE";
cmd.ExecuteNonQuery();
cmd.Parameters.Clear();
cmd.CommandText = "SET ANSI_WARNINGS ON";
cmd.ExecuteNonQuery();
trans.Commit();
}
}
catch (Exception)
{
trans.Rollback();
}
}
conn.Close();
}
I had the same issue. The length of my column was too short.
What you can do is either increase the length or shorten the text you want to put in the database.
Also had this problem occurring on the web application surface.
Eventually found out that the same error message comes from the SQL update statement in the specific table.
Finally then figured out that the column definition in the relating history table(s) did not map the original table column length of nvarchar types in some specific cases.
I had the same problem, even after increasing the size of the problematic columns in the table.
tl;dr: The length of the matching columns in corresponding Table Types may also need to be increased.
In my case, the error was coming from the Data Export service in Microsoft Dynamics CRM, which allows CRM data to be synced to an SQL Server DB or Azure SQL DB.
After a lengthy investigation, I concluded that the Data Export service must be using Table-Valued Parameters:
You can use table-valued parameters to send multiple rows of data to a Transact-SQL statement or a routine, such as a stored procedure or function, without creating a temporary table or many parameters.
As you can see in the documentation above, Table Types are used to create the data ingestion procedure:
CREATE TYPE LocationTableType AS TABLE (...);
CREATE PROCEDURE dbo.usp_InsertProductionLocation
#TVP LocationTableType READONLY
Unfortunately, there is no way to alter a Table Type, so it has to be dropped & recreated entirely. Since my table has over 300 fields (😱), I created a query to facilitate the creation of the corresponding Table Type based on the table's columns definition (just replace [table_name] with your table's name):
SELECT 'CREATE TYPE [table_name]Type AS TABLE (' + STRING_AGG(CAST(field AS VARCHAR(max)), ',' + CHAR(10)) + ');' AS create_type
FROM (
SELECT TOP 5000 COLUMN_NAME + ' ' + DATA_TYPE
+ IIF(CHARACTER_MAXIMUM_LENGTH IS NULL, '', CONCAT('(', IIF(CHARACTER_MAXIMUM_LENGTH = -1, 'max', CONCAT(CHARACTER_MAXIMUM_LENGTH,'')), ')'))
+ IIF(DATA_TYPE = 'decimal', CONCAT('(', NUMERIC_PRECISION, ',', NUMERIC_SCALE, ')'), '')
AS field
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = '[table_name]'
ORDER BY ORDINAL_POSITION) AS T;
After updating the Table Type, the Data Export service started functioning properly once again! :)
When I tried to execute my stored procedure I had the same problem because the size of the column that I need to add some data is shorter than the data I want to add.
You can increase the size of the column data type or reduce the length of your data.
A 2016/2017 update will show you the bad value and column.
A new trace flag will swap the old error for a new 2628 error and will print out the column and offending value. Traceflag 460 is available in the latest cumulative update for 2016 and 2017:
https://support.microsoft.com/en-sg/help/4468101/optional-replacement-for-string-or-binary-data-would-be-truncated
Just make sure that after you've installed the CU that you enable the trace flag, either globally/permanently on the server:
...or with DBCC TRACEON:
https://learn.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-traceon-trace-flags-transact-sql?view=sql-server-ver15
Another situation, in which this error may occur is in
SQL Server Management Studio. If you have "text" or "ntext" fields in your table,
no matter what kind of field you are updating (for example bit or integer).
Seems that the Studio does not load entire "ntext" fields and also updates ALL fields instead of the modified one.
To solve the problem, exclude "text" or "ntext" fields from the query in Management Studio
This Error Comes only When any of your field length is greater than the field length specified in sql server database table structure.
To overcome this issue you have to reduce the length of the field Value .
Or to increase the length of database table field .
If someone is encountering this error in a C# application, I have created a simple way of finding offending fields by:
Getting the column width of all the columns of a table where we're trying to make this insert/ update. (I'm getting this info directly from the database.)
Comparing the column widths to the width of the values we're trying to insert/ update.
Assumptions/ Limitations:
The column names of the table in the database match with the C# entity fields. For eg: If you have a column like this in database:
You need to have your Entity with the same column name:
public class SomeTable
{
// Other fields
public string SourceData { get; set; }
}
You're inserting/ updating 1 entity at a time. It'll be clearer in the demo code below. (If you're doing bulk inserts/ updates, you might want to either modify it or use some other solution.)
Step 1:
Get the column width of all the columns directly from the database:
// For this, I took help from Microsoft docs website:
// https://learn.microsoft.com/en-us/dotnet/api/system.data.sqlclient.sqlconnection.getschema?view=netframework-4.7.2#System_Data_SqlClient_SqlConnection_GetSchema_System_String_System_String___
private static Dictionary<string, int> GetColumnSizesOfTableFromDatabase(string tableName, string connectionString)
{
var columnSizes = new Dictionary<string, int>();
using (var connection = new SqlConnection(connectionString))
{
// Connect to the database then retrieve the schema information.
connection.Open();
// You can specify the Catalog, Schema, Table Name, Column Name to get the specified column(s).
// You can use four restrictions for Column, so you should create a 4 members array.
String[] columnRestrictions = new String[4];
// For the array, 0-member represents Catalog; 1-member represents Schema;
// 2-member represents Table Name; 3-member represents Column Name.
// Now we specify the Table_Name and Column_Name of the columns what we want to get schema information.
columnRestrictions[2] = tableName;
DataTable allColumnsSchemaTable = connection.GetSchema("Columns", columnRestrictions);
foreach (DataRow row in allColumnsSchemaTable.Rows)
{
var columnName = row.Field<string>("COLUMN_NAME");
//var dataType = row.Field<string>("DATA_TYPE");
var characterMaxLength = row.Field<int?>("CHARACTER_MAXIMUM_LENGTH");
// I'm only capturing columns whose Datatype is "varchar" or "char", i.e. their CHARACTER_MAXIMUM_LENGTH won't be null.
if(characterMaxLength != null)
{
columnSizes.Add(columnName, characterMaxLength.Value);
}
}
connection.Close();
}
return columnSizes;
}
Step 2:
Compare the column widths with the width of the values we're trying to insert/ update:
public static Dictionary<string, string> FindLongBinaryOrStringFields<T>(T entity, string connectionString)
{
var tableName = typeof(T).Name;
Dictionary<string, string> longFields = new Dictionary<string, string>();
var objectProperties = GetProperties(entity);
//var fieldNames = objectProperties.Select(p => p.Name).ToList();
var actualDatabaseColumnSizes = GetColumnSizesOfTableFromDatabase(tableName, connectionString);
foreach (var dbColumn in actualDatabaseColumnSizes)
{
var maxLengthOfThisColumn = dbColumn.Value;
var currentValueOfThisField = objectProperties.Where(f => f.Name == dbColumn.Key).First()?.GetValue(entity, null)?.ToString();
if (!string.IsNullOrEmpty(currentValueOfThisField) && currentValueOfThisField.Length > maxLengthOfThisColumn)
{
longFields.Add(dbColumn.Key, $"'{dbColumn.Key}' column cannot take the value of '{currentValueOfThisField}' because the max length it can take is {maxLengthOfThisColumn}.");
}
}
return longFields;
}
public static List<PropertyInfo> GetProperties<T>(T entity)
{
//The DeclaredOnly flag makes sure you only get properties of the object, not from the classes it derives from.
var properties = entity.GetType()
.GetProperties(System.Reflection.BindingFlags.Public
| System.Reflection.BindingFlags.Instance
| System.Reflection.BindingFlags.DeclaredOnly)
.ToList();
return properties;
}
Demo:
Let's say we're trying to insert someTableEntity of SomeTable class that is modeled in our app like so:
public class SomeTable
{
[Key]
public long TicketID { get; set; }
public string SourceData { get; set; }
}
And it's inside our SomeDbContext like so:
public class SomeDbContext : DbContext
{
public DbSet<SomeTable> SomeTables { get; set; }
}
This table in Db has SourceData field as varchar(16) like so:
Now we'll try to insert value that is longer than 16 characters into this field and capture this information:
public void SaveSomeTableEntity()
{
var connectionString = "server=SERVER_NAME;database=DB_NAME;User ID=SOME_ID;Password=SOME_PASSWORD;Connection Timeout=200";
using (var context = new SomeDbContext(connectionString))
{
var someTableEntity = new SomeTable()
{
SourceData = "Blah-Blah-Blah-Blah-Blah-Blah"
};
context.SomeTables.Add(someTableEntity);
try
{
context.SaveChanges();
}
catch (Exception ex)
{
if (ex.GetBaseException().Message == "String or binary data would be truncated.\r\nThe statement has been terminated.")
{
var badFieldsReport = "";
List<string> badFields = new List<string>();
// YOU GOT YOUR FIELDS RIGHT HERE:
var longFields = FindLongBinaryOrStringFields(someTableEntity, connectionString);
foreach (var longField in longFields)
{
badFields.Add(longField.Key);
badFieldsReport += longField.Value + "\n";
}
}
else
throw;
}
}
}
The badFieldsReport will have this value:
'SourceData' column cannot take the value of
'Blah-Blah-Blah-Blah-Blah-Blah' because the max length it can take is
16.
Kevin Pope's comment under the accepted answer was what I needed.
The problem, in my case, was that I had triggers defined on my table that would insert update/insert transactions into an audit table, but the audit table had a data type mismatch where a column with VARCHAR(MAX) in the original table was stored as VARCHAR(1) in the audit table, so my triggers were failing when I would insert anything greater than VARCHAR(1) in the original table column and I would get this error message.
I used a different tactic, fields that are allocated 8K in some places. Here only about 50/100 are used.
declare #NVPN_list as table
nvpn varchar(50)
,nvpn_revision varchar(5)
,nvpn_iteration INT
,mpn_lifecycle varchar(30)
,mfr varchar(100)
,mpn varchar(50)
,mpn_revision varchar(5)
,mpn_iteration INT
-- ...
) INSERT INTO #NVPN_LIST
SELECT left(nvpn ,50) as nvpn
,left(nvpn_revision ,10) as nvpn_revision
,nvpn_iteration
,left(mpn_lifecycle ,30)
,left(mfr ,100)
,left(mpn ,50)
,left(mpn_revision ,5)
,mpn_iteration
,left(mfr_order_num ,50)
FROM [DASHBOARD].[dbo].[mpnAttributes] (NOLOCK) mpna
I wanted speed, since I have 1M total records, and load 28K of them.
This error may be due to less field size than your entered data.
For e.g. if you have data type nvarchar(7) and if your value is 'aaaaddddf' then error is shown as:
string or binary data would be truncated
You simply can't beat SQL Server on this.
You can insert into a new table like this:
select foo, bar
into tmp_new_table_to_dispose_later
from my_table
and compare the table definition with the real table you want to insert the data into.
Sometime it's helpful sometimes it's not.
If you try inserting in the final/real table from that temporary table it may just work (due to data conversion working differently than SSMS for example).
Another alternative is to insert the data in chunks, instead of inserting everything immediately you insert with top 1000 and you repeat the process, till you find a chunk with an error. At least you have better visibility on what's not fitting into the table.
I have a PDF document that has several hundred fields. All of the field names have periods in them, such as "page1.line1.something"
I want to remove these periods and replace them with either an underscore or (better) nothing at all
There appears to be a bug in the itextsharp libraries where the renamefield method does not work if the field has a period, so the following does not work (always returns false)
Dim formfields As AcroFields = stamper.AcroFields
Dim renametest As Boolean
renametest = formfields.RenameField("page1.line1.something", "page1_line1_something")
If the field does not have a period in it, it works fine.
Has anyone come across this and is there a workaround?
Is this an AcroForm form or a LiveCycle Designer (xfa) form?
If it's XFA (which is likely given the field names), iText can't help you. It can only get/set field values when working with XFA.
Okay, an AcroForm. Rather than go the route used in your source, I suggest you directly manipulate the existing field dictionaries and the acroForm field list.
I'm a Java native when it comes to iText, so you'll have to do some translation, but here goes:
A) Delete the AcroForm's field array. Leave the calculation order alone if present (/CO). I think.
PdfDictionary acroDict = reader.getCatalog().getAsDictionary(PdfName.ACROFORM);
acroDict.remove(PdfName.FIELDS);
B) Attach all the 'top level' fields to a new FIELDS array.
PdfArray newFldArray = new PdfArray();
acroDict.put(newFldArray, PdfName.FIELDS);
// you could wipe this between pages to speed things up a bit
Set<PdfIndirectReference> radioFieldsAdded = new HashSet<PdfIndirectReference>();
int numPages = reader.getNumberOfPages();
for (int curPg = 1; curPg <= numPages; ++curPg) {
PdfDictionary curPageDict = reader.getPageN(curPg);
PdfArray annotArray = curPageDict.getAsArray(PdfName.ANNOTS);
if (annotArray == null)
continue;
for (int annotIdx = 0; annotIdx < annotArray.size(); ++annotIdx) {
PdfIndirectReference fieldReference = (PdfIndirectReference) annotArray.getAsIndirect(annotIdx);
PdfDictionary field = (PdfDictionary)PdfReader.getObject(fieldReference);
// if it's a radio button
if ((PdfFormField.FF_RADIO & field.getAsNumber(PdfName.FF).intValue()) != 0) {
fieldReference = field.get(pdfName.PARENT);
field = field.getAsDict(PdfName.PARENT); // looks up indirect reference for you.
// only add each radio field once.
if (radioFieldsAdded.contains(fieldReference)) {
continue;
} else {
radioFieldsAdded.add(fieldReference);
}
}
field.remove(PdfName.PARENT);
// you'll need to assemble the original field name manually and replace the bits
// you don't like. Parent.T + '.' child.T + '.' + ...
String newFieldName = SomeFunction(field);
field.put(PdfName.T, new PdfString( newFieldName ) );
// add the reference, not the dictionary
newFldArray.add(fieldReference)
}
}
C) Clean up
reader.removeUnusedObjects();
Disadvantage:
More Work.
Advantages:
Maintains all field types, attributes, appearances, and doesn't change the file as a whole all that much. Less CPU & memory.
Your existing code ignores field script, all the field flags (read only, hidden, required, multiline text, etc), lists/combos, radio buttons, and quite a few other odds and ends.
if you use periods in your field name, only the last part can be renamed, e.g. in page1.line1.something only "something" can be renamed. This is because the "page1" and "line1" are treated by adobe as parents to the "something" field
I needed to delete this hierarchy and replace it with a flattened structure
I did this by
creating a pdfdictionary object for each field
reading the annotations I needed for each field into an array
deleting the field hierarchy in my (pdfstamper) document
creating a new set of fields from my array data
I have created some sample code for this if you want to see how I did it.
