I have a query that gets a string column containing a date, ex. 20040825.
If I use the property builder to format the string to 08/25/2004 it does not
work because it only accepts datetime columns. How can I convert or format
the string. Could I add a new dataset/datatable column containing the value
as I need it.
Thanks.

Hi all,
I have the following codes, but SCOPE_IDENTITY() just returns NULL to
me. If I comment out SCOPE_IDENTITY() line and run @@IDENTITY line, it works
fine!! Since I have a trigger on the table, I have to use SCOPE_IDENTITY().
Any ideas?
