I was inserting some stuff into a database today and got the following error "String or binary data would be truncated."  I hadn't seen it before.  I looked at my code and coudln't find anything wrong.  I then retried the INSERT with the EXACT same data, and it worked fine.  Have any idea what the error is or where it comes from?

Yupe, the length of the data you insert (usually string) exceeds the length of the field.

For example:
tabel: PRODUCT
field: productname varchar(10)


You do this:
INSERT INTO Product('1234567890123')

It will raise the error.

If you tried the insert with the same data then it implies that it it is not just the values that are too long.

How were you doing the insert that fails.
I suspect your test was via query analyser and there is something in the interface that failed previously.

I was doing the insert via an Activer Server Page.

error "String or binary data
would be truncated."  is showed only if the SET ANSI_WARNINGS is ON. If you tried to insert the same data in the table with ANSI_WARNINGS set OFF it will not raise any error and it will automaticly truncate your data to max size of the field.
Probably you got the error in enviroment with set ANSI_WARNINGS ON, and normaly it is set OFF.
Check your ODBC settings if your application uses ODBC, or if you use Query Analizer, just type:
SET ANSI_WARNINGS OFF
  hope this will help!
