I am facing issues when importing large data values into a pre-defined data table in SQL. Any value larger or equal to 100,000,000 (one hundred million) creates an error and fails upon import. A value of 99,999,999 is fine. Does anyone know what is going on and how to solve this, please?
Notes:
The data table I import data to is pre-defined; I can only append rows. The target column is defined as float(Null). The import wizard seems to set the data type to float automatically. I could not change it to numeric or decimal because a) I do not have the admin rights, and b) there is something funny with the source data when trying to import. But I cannot see anything to be off when looking at it in Excel; all values are numeric and the max length is only 11.
The files I use are in .csv format and many have more than 1 million rows. I tried splitting them up using Python and saving them in .xlsx format to put them through an Excel formatting step, but that did not help.
I am using the import wizard, SMSS v.18.12.1, and the SQL Server Native Client 11.0 of the import wizard.
The error message I get is:
`
Error 0xc02020c5: Data Flow Task 1: Data conversion failed while converting column "ColumnName" (42) to column "ColumnName" (148). The conversion returned status value 6 and status text "Conversion failed because the data value overflowed the specified type.".

I have a SQL Server table that contains columns of type varchar(MAX) and I'm trying to get a .csv (UTF-8) type export but I get this error instead.
I want to know how I can change this data type to nvarchar(MAX) without losing data. Can anyone help?

I have looked into similar questions, where I have the same problem but I don't know how to use CAST or CONVERT in the query
You can solve this in 3 ways:
CAST your source columns to NVARCHAR in the initial SELECT, e.g. CAST(mycolumn as nvarchar(column_length))
Use a SSIS Data Conversion task to convert the strings to Unicode
Set Flat File Connection Manager's code page to '1252 ANSI - Latin I'
(65001 Code page = Unicode (UTF-8))
You might find that the 3rd option is easiest.
My predecessor created an Access database in 2007, which has a number of tables, forms and query.
One of the tables holds images, which are stored as attachments.
The database is almost 2GB in size (compacting and repairing doesn't change it). So I'd like to convert it to a SQL Server 2014 database.
I've used the Data Import tool, which has copied the tables & data into SQL Server. But the attachments are just converted to a string of their file name (image1.jpg)
Is there anyway to import the images from the MS Access database in to the SQL Server?
I also have a Sharepoint 2010 server, would this be a better option?
Update (sorry new to Stack Overflow, not sure what to put where)
I've changed the field mapping in import wizard to IMAGE, and I get the following error. If I set it to ignore, the fields are blank. using VARSTRING, puts either Null or 0x in the field.

You've used SQL Server to import the data which is a good thing. I would probably use data type IMAGE for the column to hold the images. You could also try the data typoe VARBINARY(MAX).
Use the Import and Export WIzard to import the data en see which datatype works.
Hope this helps you out.
Edit:
You say when you convert the attachment table you only have the names of the images. Are these names related to the images. When you still have the images you can store them in a folder and use FILESTREAM to connect to thme using SQL Server.
Using FILESTREAM enhances the database because the data of the images is no longer saved in the database, only a reference to them.
Unfortunately SQL Server doesn't support multi-valued or attachment like fields.
For more information about FILESTREAM look at this website: http://msdn.microsoft.com/library/hh461480
I'm trying to insert a large CSV file (several gigs) into SQL Server, but once I go through the Import Wizard and finally try to import the file I get the following error report:

I created the table to insert the file into first, and I set each column to hold varchar(MAX), so I don't understand how I can still have this truncation issue. What am I doing wrong?
In SQL Server Import and Export Wizard you can adjust the source data types in the Advanced tab (these become the data types of the output if creating a new table, but otherwise are just used for handling the source data).
The data types are annoyingly different than those in MS SQL, instead of VARCHAR(255) it's DT_STR and the output column width can be set to 255. For VARCHAR(MAX) it's DT_TEXT.
So, on the Data Source selection, in the Advanced tab, change the data type of any offending columns from DT_STR to DT_TEXT (You can select multiple columns and change them all at once).
This answer may not apply universally, but it fixed the occurrence of this error I was encountering when importing a small text file. The flat file provider was importing based on fixed 50-character text columns in the source, which was incorrect. No amount of remapping the destination columns affected the issue.
To solve the issue, in the "Choose a Data Source" for the flat-file provider, after selecting the file, a "Suggest Types.." button appears beneath the input column list. After hitting this button, even if no changes were made to the enusing dialog, the Flat File provider then re-queried the source .csv file and then correctly determined the lengths of the fields in the source file.
Once this was done, the import proceeded with no further issues.
I think its a bug, please apply the workaround and then try again: http://support.microsoft.com/kb/281517.
Also, go into Advanced tab, and confirm if Target columns length is Varchar(max).
The Advanced Editor did not resolve my issue, instead I was forced to edit dtsx-file through notepad (or your favorite text/xml editor) and manually replace values in attributes to
length="0" dataType="nText" (I'm using unicode)
Always make a backup of the dtsx-file before you edit in text/xml mode.
Running SQL Server 2008 R2
Goto Advanced tab----> data type of column---> Here change data type from DT_STR to DT_TEXT and column width 255. Now you can check it will work perfectly.
Issue:
The Jet OLE DB provider reads a registry key to determine how many rows are to be read to guess the type of the source column.
By default, the value for this key is 8. Hence, the provider scans the first 8 rows of the source data to determine the data types for the columns. If any field looks like text and the length of data is more than 255 characters, the column is typed as a memo field. So, if there is no data with a length greater than 255 characters in the first 8 rows of the source, Jet cannot accurately determine the nature of the data type.
As the first 8 row length of data in the exported sheet is less than 255 its considering the source length as VARCHAR(255) and unable to read data from the column having more length.
Fix:
The solution is just to sort the comment column in descending order.
In 2012 onwards we can update the values in Advance tab in the Import wizard.
I am using the SQL Server Import and Export Wizard to try to import a particular xlsx spreadsheet into an existing table in SQL. The existing table contains a sub-set of the columns in the spreadsheet and I am ignoring the many columns that don't match.
The spreadsheet has 123 columns and 238 lines of data.
Initially when I was importing the spreadsheet the wizard was hanging on 'Executing' and I had to kill the process. Something I have never come across before.
After copy and pasting the data into a new spreadsheet it is now coming up with the following error:
Error 0xc020901c: Data Flow Task 1: There was an error with output column "Confidentiality Clause Comments" (108) on output "Excel Source Output" (9). The column status returned was: "Text was truncated or one or more characters had no match in the target code page.".

A truncation error occurred on the specified object of the specified component.
(SQL Server Import and Export Wizard)
What I am confused about it, the column "Confidentiality Clause Comments" is one of the columns being ignored - it is not being imported into the database!
I have tried setting "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Jet 4.0\Engines\Excel\TypeGuessRows" to both 0 and higher numbers like 238 and 1000 to increase the sample size. (Although the table does already exist with fields large enough for the data being imported). I also have the "On Truncation (global)" and "On Error (global)" set to Ignore (but this setting seems to be 'ignored').
I have also tried importing the data into a new table, and get the same truncation error message (but on different fields dependant on the data sort).
I thought about importing as a CSV file but there are embedded comma's in many of the fields and it completely messed the data up.
Any ideas on how to get data imported? I have spent over 3 hours on this already, and have got nowhere.
Thanks,Steve
Instead of CSV, you could save as Text (Tab delimited) (*.txt) - that way you won't encounter the comma problem.
Also, if you only need to do this once, and because the dataset is not exactly huge, I'd consider just copying from excel and pasting directly into sql server management studio.

What i'm doing wrong? This file was a export from a query, then i delete all records and try to import.
The flat file import task will default lengths to VARCHAR(50). You need to go to the Advanced property of the flat file connection page and change the length manually to match the destination table. There should also be an option to Suggest Types which may match the metadata that you're using, but it does a sampling of rows from the file so it may not be as accurate as just setting types manually.
It may be that you're trying to import data from the CSV which is too large for the field you're importing it in to. Perhaps you need to increase the size of your fields in your SQL table?
Have you tried to import a single, very small line of data from the CSV to see if that works? If it does, excessively large data somewhere in the rest of the sheet may be the problem.
