That depends on what you actually want to do - that won't work at all.
If you are trying to retrieve a subset of the records based on a criteria then perhaps:

C#

string queryStr = "SELECT * FROM Inventory WHERE foodID= @fID AND inventoryID= @iID";

If you are trying to order all the records by two columns then try:

C#

string queryStr = "SELECT * FROM Inventory ORDER BY foodID, inventoryID";

If you want some combination, then you need to explain exactly what combination you are looking for.

if its is filtered why the order by clause needed there

Karthik_Mahalingam 4-Feb-14 0:45am

filter will do narrow down the results,
order by will order the records in such a fashion to display in asc or desc order.

Thava Rajan 4-Feb-14 0:47am

thanks for your info
but here we just filter the foodid and inventoryid and again you just add the order by on it, is it needed?

Karthik_Mahalingam 4-Feb-14 0:52am

see it depends on the design of the DB,
if FoodID is Primary KEy then no use of ORDER BY
all i wanted to show his , how to use filter and oRDER BY
