Hi,
I want to concatenate fields from a table into a combo box. I entered the following SQL Select statement:
SelectCommand="SELECT Project + ' ' + Task + ' ' + [Sub Task] + ' ' + Description AS RAS FROM RAS_Codes">
The [Sub Task] field has empty rows and when the query returns the results it omits all of the rows in which [Sub Task] is empty.
How do I get the query to return all of the rows - even those with no values in fields?
Thank you,
John

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Ms. Pettis,

Thank you very much for your reply. I did the following and it works fine.

SelectCommand="SELECT Project + ' - ' + Task + ' - ' + Iif(isnull(SubTask),' (No Sub Task) ',SubTask) + ' - ' + Description AS RAS FROM RAS_Codes">
