Hello, I apologize in advance if there have been lots of questions like this, but the search won't let me use AND as a search term!

I have two related 1 to many tables. The parent table contains clients, and the child table contains categories, each client can have many categories. (i originally intended to have the categories be columns in the client table, in which case what i want to do is easy, however, then it becomes a nightmare when the user wants to add a new category hence the related situation described.)

Is there an easy way to find all the clients who have both category 7 and category 10? I can do it writing a query to find all the 7s, then another to find all the 10s, and a third to find those which have both. I am hoping there is an easier way, as i need to give the user a way to search via categories in whatever combination they fancy. The OR's i can do easily it's the AND's that are causing the problem.

The only idea i have at the moment is to make a temp table with the the clientid, and a long field holding each of the category ids, seperated by commas, and then searching using like "*7*" and like "*10*".

Does anyone have any better ideas, i'm hoping i'm missing something really obvious......

Thanks, Anna
 
Hello Ana!

It is a bad idea to put two values in one field (7 and 10).
In a field only one value.
In that case you can't to us AND, only OR.
AND you can use when CRITERIA is composing ot two or more fields.
