Re: [MS_AccessPros] Example of subquery.

 

John-
Thanks for your reply. I think an example might be the best way to see how a subquery works. Please help.
Best Regards,
Kevin

Life has an uncanny way of responding to your need.

Kevin-


What are you trying to learn?  A subquery is simply a subset of data using a SELECT statement enclosed in parentheses.  You can have a table subquery (multiple columns and rows), a list subquery (one column returning a value from multiple rows), or a scalar subquery (one column returning exactly one value).  Using a subquery isn't dependent on the version of Access unless you go back earlier than Version 2.
