Hi,
In typed dataset - tableadapter query I would like to use an if-then sql query statement but I can't seem to get it to work.   Not even sure if it's poss at all.
Anyway, my straight sql code sofar isn't accepted by the query builder:

IF (@prg_id = 2)
BEGIN
SELECT CAST(grp_no AS varchar) + '.0' + CAST(itm_no AS varchar) + '  ' + CAST(grp_type AS varchar) + '  ' + CAST(itm_desc AS varchar) AS Combi, itm_id
FROM v_Items_Groups WHERE (itm_end > GETDATE()) AND (prg_id = @prg_id )
END
ELSE
SELECT CAST(grp_no AS varchar) + '.' + CAST(itm_no AS varchar) + '  ' + CAST(grp_type AS varchar) + '  ' + CAST(itm_desc AS varchar) AS Combi, itm_id
FROM v_Items_Groups WHERE (itm_end > GETDATE()) AND (prg_id = @prg_id)

error :
The Compound statement SQL construct or statement is not supported.

Is this solvable ?

I know I can create more query's and do a Select Case in the VB code of the originating page but this would be just a bit more flex.

why not put that in a SQL view or stored procedure and bind to the view/sproc?

also, I'd add the BEGIN/END to the else statement.

Hi whityum,
I have this datatable- tableadapter config and use it widely in the app allready and would like to solve it with an If - Then in the query.
Other solutions I know are poss but I'm wondering if the above would go.
- add the BEGIN/END to the else statement, indeed, but doesn't change the error  :-)

i just thought there was more.   i wonder if the table adapter won't support it because it's updateable and you couldn't update based on that query

have you tried using a sqldataadapter or IDataReader instead of the table adapter to bind it to?

that's possible but when you create a new query for your table adapter you may specify if it's a Select, an Update etc.  As this is only a select it should be possible to use some more complex SQL statement in it.
But then again, maybe not....
