I have to create a table with name "Realizations" but it's file must be named like today's date (example "12092016.dbf"). I can get current date from my C# program but how to set the file name in query string???
My data engine is Visual FoxPro.
Is this what you mean? (I assume you mean C# code):
using (var connection = new OleDbConnection(#"Provider=VFPOLEDB;Data Source=c:\My Data Folder"))
{
var cmd = new OleDbCommand(#"select * from Realizations
into table (?)",connection);
cmd.Parameters.AddWithValue("tableName", DateTime.Today.ToString("ddMMyyyy"));
connection.Open();
cmd.ExecuteNonQuery();
connection.Close();
}
Please note that, naming a table like this is not very safe and also a date string in the format ddMMyyyy is not very safe. Maybe you would want to name it like Realizations_20160913. If so then you could say:
cmd.Parameters.AddWithValue("tableName", "Realizations_" +
DateTime.Today.ToString("yyyyMMdd"));

I'm currently creating a flat file export for one of our clients, i've managed to get the file in the format they want, i'm trying to get the easiest way of creating a dynamic file name. I've got the date in as a variable and the path ect but they want a count in the file name. For example
File name 1 : TDY_11-02-2013_{1}_T1.txt. The {} being the count. So next weeks file would be TDY_17-02-2013_{2}_T1.txt
I cant see an easy way of doing this!! any idea's??
EDIT:
on my first answer, I thought you meant count of values returned on a query. My bad!
two ways to achieve this, you could loop into the destination folder, select the last file by date, get its value and increase 1, which sound like a lot of trouble. Why not a simple log table on the DB with last execution date and ID and then you compose your file name base on the last row of this table?
where exactly is your problem?
you can make a dynamic file name using expressions:
the count, you can use a "row count" component inside your data flow to assign the result to a variable and use the variable on your expression:
Use Script task and get the number inside the curly braces of the file name and store it in a variable.
Create a variable(FileNo of type int) which stores the number for the file
Pseudo code
string name = string.Empty;
string loction = #"D:\";
/* Get the path from the connection manager like the code below
instead of hard coding like D: above
string flatFileConn =
(string(Dts.Connections["Yourfile"].AcquireConnection(null) as String);
*/
string pattern = string.Empty;
int number = 0;
string pattern = #"{([0-9])}"; // Not sure about the correct regular expression to retrieve the number inside braces
foreach (string s in Directory.GetFiles(loction,"*.txt"))
{
name = Path.GetFileNameWithoutExtension(s);
Match match = Regex.Match(name, pattern );
if (match.Success)
{
dts.Variables["User::FileNo"].Value = int.Parse(match.Value)+1;
}
}
Now once you get the value use it in your file expression in the connection manager
#[User::FilePath] +#[User::FileName]
+"_{"+ (DT_STR,10,1252) #[User::FileNo] + "}T1.txt"
SQL Server 2005. Visual Studio 2010. ASP.NET 2.0 Web Application
This is a web application that supports multiple languages, one of them is Korean. I have “langid” in the query string to differentiate different languages, if langid=3 it is Korean.
In my code behind’ C# code, I read a table using this query:
"select * from Reservations where rsv_id = 1234"
There is a column named "rsv_date" in the table which is reservation date, of type datetime. In the db table its value is "11/22/2012 4:14:37 PM". I checked this in SQL server management studio. But when I read it out, I got "2012-11-22 오후 4:14:37"! Where does that Korean “오후” come from??? Is it because of some culture setting anywhere? But I don’t see where, either in my code or in SQL Server. This caused problem for me, because when I modify this record, it will try to write "2012-11-22 오후 4:14:37" to the db, which of course SQL server reports error.
My original code:
Hashtable reservation = new Hashtable();
SqlCommand sqlCommand = null;
SqlDataReader dataReader;
string queryCommand = "select * from Reservations where rsv_id = #RsvID";
sqlCommand = new SqlCommand(queryCommand, getConnection());
sqlCommand.Connection.Open();
sqlCommand.Parameters.AddWithValue("#RsvID", rsvID);
dataReader = sqlCommand.ExecuteReader();
while (dataReader.Read())
{
reservation["rsvID"] = dataReader["rsv_id"];
reservation["rsvCode"] = dataReader["rsv_code"];
reservation["rsvType"] = dataReader["rsv_type"];
reservation["rsvDate"] = dataReader["rsv_date"]; // where does Korean come from?
...
}
It's a common misunderstanding that you can "check" the format of datetime fields in the database.
The format you see on screen will always depend on the client, even if the client is "SQL server management studio".
In the database, the datetime is stored in a binary format that very few need to know.
So, the Korean characters are from the client, in this case your own program.
And Yes, they will depend on some culture setting somewhere.
Your example doesn't show what happens to reservation["rsvDate"] , where is the value displayed with the Korean characters ?
How are you trying to write the value with Korean characters to the database ?
To avoid Korean characters you could use .ToString(CultureInfo.InvariantCulture) where you use the Date value.
Hey I want to Fetch the date from the date picker and add that date into my database birthdate column
soo plzzz help me out...
here Form View
and Grid View
just tell me syntax how to store the date value in Database birthdate column!
plzzz give me solution in C#.net only...
WinForms: The datepicker has a property called "Value" and it is of DateTime data type. Use that.
Web Forms: if you are using JQuery, just do
var date = $("#myDateControl").val();
Then how you store the value depends on what database you are using (Sql, Oracle, etc) and whether you are using Entity Framework (or other ORM) or not... give more details if you want a more thorough answer.
EDIT
Based on your comments, I would do something like this:
using (var connection - new SqlConnection("my connection string"))
{
using (var command = connection.CreateCommand())
{
command.CommandText = string.Format("INSERT INTO Stu_inf(Enrollno, Firstname, Lastname, Birthdate) VALUES ('{0}', '{1}', '{2}', '{3}')", txtEnrollno.Text, txtFname.Text, txtLname.Text, mtxtBdate.Value.ToString("yyyy-MM-dd"));
connection.Open();
command.ExecuteNonQuery();
connection.Close();
}
}
I wrote this all from memory, so you may get a small syntax error or something.. but that's the idea... hope it helps
I basically need to know how to import SQL code into Access. I've tried one way but that requires me to do one table and one value at a time which takes a lot of time.
Can anyone help?
If you are trying to import data, rather than SQL code (see Duffymo's response), there are two ways.
One is to go where the data is and dump a .CSV file and import that, as Duffymo responded.
The other is to create a table link from the Access database to a table in the source database. If the two databases will talk to each other this way, you can use the data in the remote table as if it were in the Access database.
Well, some days ago I needed to shift data from an Access database to SQL (reverse of what you're doing). I found it simpler to write a simple script that would read data from my access database and insert it into SQL.
I don't think doing what you need to do is any different.
I don't know if it will help, but I posting my code (It's a simple C# function). You can just change the connections and it will work. Of course I only had 3 fields so I hard-coded them. You can do the same for your db schema.
protected void btnProcess_Click(object sender, EventArgs e)
{
//Open the connections to the access and SQL databases
string sqlDBCnn = #"Data Source=.\SQLEXPRESS;Integrated Security=True;AttachDBFileName=|DataDirectory|\mydb.mdf;user instance=true";
string accessDBCnn = #"Provider=Microsoft.Jet.OleDB.4.0;Data Source=C:\mydb.mdb";
OleDbConnection cnnAcc = new OleDbConnection(accessDBCnn);
cnnAcc.Open();
SqlConnection cnnSql = new SqlConnection(sqlDBCnn);
cnnSql.Open();
SqlCommand cmSql = new SqlCommand("DELETE tablename", cnnSql);
cmSql.ExecuteNonQuery();
//Retrieve the data from the Access Database
OleDbCommand cmdAcc = new OleDbCommand("SELECT * FROM tablename", cnnAcc);
OleDbDataReader drAcc = cmdAcc.ExecuteReader();
using (drAcc)
{
if (drAcc.HasRows)
{
//Loop through the access database records and add them to the database
while (drAcc.Read())
{
SqlCommand cmdSql = new SqlCommand("INSERT INTO tablename(Category, Head, Val) VALUES(#cat,#head,#val)",cnnSql);
SqlParameter parCat = new SqlParameter("cat",System.Data.SqlDbType.VarChar,150);
SqlParameter parHead = new SqlParameter("head",System.Data.SqlDbType.VarChar,150);
SqlParameter parVal = new SqlParameter("val",System.Data.SqlDbType.VarChar);
parCat.Value = drAcc["Category"].ToString();
parHead.Value = drAcc["Head"].ToString();
parVal.Value = drAcc["Val"].ToString();
cmdSql.Parameters.Add(parCat);
cmdSql.Parameters.Add(parHead);
cmdSql.Parameters.Add(parVal);
cmdSql.ExecuteNonQuery();
}
}
}
lblMsg.Text = "<p /> All Done Kapitone!";
}
SQL code? Or data? "one table and one value" makes me think it's the latter. If so, I'd suggest dumping the data out into a .csv file and importing that into Access tables.
Or maybe using a tool like Microsoft's DTS to map and move the data between sources. That would be the best idea.
I guess you are talking about "importing" both structure and data from SQL to ACCESS. ACCESS does not accept standard TSQL scripts that you could generate directly from your SQL Database. There are some commercial products like EMS that can more or less do the job for you. EMS has a data exporter module that can take your SQL data in different formats, including Access.
Another way would be to open an Access file and write some basic VBA code, taking advantage of the DoCmd.TransferDatabase method, where you can link OR copy tables from other databases into Access.
I forgot if these methods also allow the transfer of a 'clean' database model, including primary keys and relations... You'll have to give it a try.
I need to import a large CSV file into an SQL server. I'm using this :
BULK
INSERT CSVTest
FROM 'c:\csvfile.txt'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO
problem is all my fields are surrounded by quotes (" ") so a row actually looks like :
"1","","2","","sometimes with comma , inside", ""
Can I somehow bulk import them and tell SQL to use the quotes as field delimiters?
Edit: The problem with using '","' as delimiter, as in the examples suggested is that :
What most examples do, is they import the data including the first " in the first column and the last " in the last, then they go ahead and strip that out. Alas my first (and last) column are datetime and will not allow a "20080902 to be imported as datetime.
From what I've been reading arround I think FORMATFILE is the way to go, but documentation (including MSDN) is terribly unhelpfull.
Try FIELDTERMINATOR='","'
Here is a great link to help with the first and last quote...look how he used the substring the SP
http://www.sqlteam.com/article/using-bulk-insert-to-load-a-text-file
Another hack which I sometimes use, is to open the CSV in Excel, then write your sql statement into a cell at the end of each row.
For example:
=concatenate("insert into myTable (columnA,columnB) values ('",a1,"','",b1,"'")")
A fill-down can populate this into every row for you. Then just copy and paste the output into a new query window.
It's old-school, but if you only need to do imports once in a while it saves you messing around with reading all the obscure documentation on the 'proper' way to do it.
Try OpenRowSet. This can be used to import Excel stuff. Excel can open CSV files, so you only need to figure out the correct [ConnectionString][2].
[2]: Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=c:\txtFilesFolder\;Extensions=asc,csv,tab,txt;
I know this isn't a real solution but I use a dummy table for the import with nvarchar set for everything. Then I do an insert which strips out the " characters and does the conversions. It isn't pretty but it does the job.
Id say use FileHelpers its an open source library
Do you need to do this programmatically, or is it a one-time shot?
Using the Enterprise Manager, right-click Import Data lets you select your delimiter.
You have to watch out with BCP/BULK INSERT because neither BSP or Bulk Insert handle this well if the quoting is not consistent, even with format files (even XML format files don't offer the option) and dummy ["] characters at the beginning and end and using [","] as the separator. Technically CSV files do not need to have ["] characters if there are no embedded [,] characters
It is for this reason that comma-delimited files are sometimes referred to as comedy-limited files.
OpenRowSet will require Excel on the server and could be problematic in 64-bit environments - I know it's problematic using Excel in Jet in 64-bit.
SSIS is really your best bet if the file is likely to vary from your expectations in the future.
u can try this code which is very sweet if you want ,
this will remove unwanted semicolons from your code.
if for example your data is like this :"Kelly","Reynold","kelly#reynold.com"
Bulk insert test1
from 'c:\1.txt' with (
fieldterminator ='","'
,rowterminator='\n')
update test1<br>
set name =Substring (name , 2,len(name))
where name like **' "% '**
update test1
set email=substring(email, 1,len(email)-1)
where email like **' %" '**
Firs you need to import CSV file into Data Table
Then you can insert bulk rows using SQLBulkCopy
using System;
using System.Data;
using System.Data.SqlClient;
namespace SqlBulkInsertExample
{
class Program
{
static void Main(string[] args)
{
DataTable prodSalesData = new DataTable("ProductSalesData");
// Create Column 1: SaleDate
DataColumn dateColumn = new DataColumn();
dateColumn.DataType = Type.GetType("System.DateTime");
dateColumn.ColumnName = "SaleDate";
// Create Column 2: ProductName
DataColumn productNameColumn = new DataColumn();
productNameColumn.ColumnName = "ProductName";
// Create Column 3: TotalSales
DataColumn totalSalesColumn = new DataColumn();
totalSalesColumn.DataType = Type.GetType("System.Int32");
totalSalesColumn.ColumnName = "TotalSales";
// Add the columns to the ProductSalesData DataTable
prodSalesData.Columns.Add(dateColumn);
prodSalesData.Columns.Add(productNameColumn);
prodSalesData.Columns.Add(totalSalesColumn);
// Let's populate the datatable with our stats.
// You can add as many rows as you want here!
// Create a new row
DataRow dailyProductSalesRow = prodSalesData.NewRow();
dailyProductSalesRow["SaleDate"] = DateTime.Now.Date;
dailyProductSalesRow["ProductName"] = "Nike";
dailyProductSalesRow["TotalSales"] = 10;
// Add the row to the ProductSalesData DataTable
prodSalesData.Rows.Add(dailyProductSalesRow);
// Copy the DataTable to SQL Server using SqlBulkCopy
using (SqlConnection dbConnection = new SqlConnection("Data Source=ProductHost;Initial Catalog=dbProduct;Integrated Security=SSPI;Connection Timeout=60;Min Pool Size=2;Max Pool Size=20;"))
{
dbConnection.Open();
using (SqlBulkCopy s = new SqlBulkCopy(dbConnection))
{
s.DestinationTableName = prodSalesData.TableName;
foreach (var column in prodSalesData.Columns)
s.ColumnMappings.Add(column.ToString(), column.ToString());
s.WriteToServer(prodSalesData);
}
}
}
}
}
This is an old question, so I write this to help anyone who stumble upon it.
SQL Server 2017 introduces the FIELDQUOTE parameter which is intended for this exact use case.
Yup, K Richard is right: FIELDTERMINATOR = '","'
See http://www.sqlteam.com/article/using-bulk-insert-to-load-a-text-file for more info.
You could also use DTS or SSIS.
Do you have control over the input format? | (pipes), and \t usually make for better field terminators.
If you figure out how to get the file parsed into a DataTable, I'd suggest the SqlBulkInsert class for inserting it into SQL Server.
