Criteria in Consult

[gatarossi]

Dear all,

I'm trying to do a consult in ms access. Then I have one criteria that
the user need to insert the value.

SELECT table1.entity, Sum(table1.sales_quantity) AS Expr1
FROM table1
GROUP BY table1.entity
HAVING (((table1.entity)=[Insert de Data:]));


But I don´t known what to do when the user want the all information,
whithout criterias...

How can I do it?

Thanks a lot!!!

André.

Change your SQL to

SELECT table1.entity, Sum(table1.sales_quantity) AS Expr1
FROM table1
GROUP BY table1.entity
WHERE table1.entity=[Insert de Data:]
OR [Insert de Data:] IS NULL

In that way, they can simply hit Enter when prompted, and everything will
appear.

Try this ---
WHERE ((table1.entity) Like IIF([Insert de Data:] Is Null, "*",[Insert de
Data:]));
