Solution 1

All it means is that you are trying to insert (or update) data to a field that has a fixed length, and the data you are passing does not fit.
For example, if your table has a UserName column that is nChar(10), and you insert 'MikeyJones' then it will work, but 'MikeyXJones' will cause a "String or binary data would be truncated." error as eleven character will not fit.

Either check and truncate before you modify the database data, or enlarge the column data size.

yes i have used varchar(max) but still i get this error..

OriginalGriff 2-Mar-13 10:37am

What columns are you inserting? What are the column definitions?

karthikeyan9966 2-Mar-13 10:55am

for file upload i've used varchar(max) data type..

OriginalGriff 2-Mar-13 11:12am

Ah. And what kind of file are you expecting...
In all probability you shouldn't be using varchar - you should most likely be using varbinary(max) or image (possibly text or ntext) - varchar and varbinary are both limited to 8000 bytes where the others support 2Gbytes.

ok now i have reduced the size of upload file..but to redirect to next page i use executescalar command but i get error on that particular line..as unhandled sqlexception executescalar command..

OriginalGriff 2-Mar-13 11:35am

Sorry? Just how do you redirect to the next page via SQL?

karthikeyan9966 2-Mar-13 11:58am

yes just to check the code is executed or not i've used this in my code...
con.open()
int result = (Int32)cmd2.ExecuteScalar();
con.Close();

if (result >= 1)
{
Response.Redirect("WebForm2.aspx");
}

I did wonder - I know of no way to redirect to any page used SQl since SQL server has absolutely no connection to the client...

The error has nothing to do with the redirect - it doesn't get to the Redirect - it's a problem with the SQL.

What code are you using to set up the SQL command you are using?
