Tableadapter insert return value

[J055]

Hi

When I do an insert using the update(datatable) method I can get the new
identity but when I do an insert directly with the Insert method I can only
get the record count because the InsertCommand uses ExecuteNonQuery.

Can I get the Insert method to return the identity?

the sproc looks like


SET NOCOUNT OFF;
INSERT INTO ...
SELECT AccountID = SCOPE_IDENTITY()

The update method obviously uses the same sproc so what is it doing
differently to get the identity?

Thanks
Andrew

Hi Andrew,

The return value from the Insert method is the rows affected. The SELECT
statement will return a result set, instead of a single identity value. In
this case, the code generated by the TableAdapter designer cannot return
the identity of the newly inserted row.

If you need to get that identity, you have to rewrite the insert method.
You can use

SET NOCOUNT OFF;
INSERT INTO ...
SELECT SCOPE_IDENTITY()

and execute with ExecuteScalar method to get it.

If anything is unclear, please feel free to let me know.
