IN (Select ... ) in Query criteria
Can someone please explain to me how and when to use an IN(Select ... )
statement in the criteria grid of a query? I've seen it used, but I don't understand it. Why is that better than 2 joined tables? -- THX cs

Sometimes a joined query will be non-editable, while the equivalent
query built using IN (Select...) will be editable.

Ok, I think I understand that. You're actually working with data from the
first (main) table (which is editable) but only with the "select" data which is matched in the "IN(Select.." criteria. Is that correct? Is the "(Select..." portion of the criteria written just as you would any SQL for a query? If not, can you give me a correct example of that syntax? -- THX cs "Jack MacDonald" wrote: Sometimes a joined query will be non-editable, while the equivalent query built using IN (Select...) will be editable.
