Darryl, The following query would return all rows in employee that existed in emp2 (**Assuming 'employee' and 'emp2' have a common field 'key').
SELECT e1.* FROM employee AS e1, emp2 AS e2 WHERE e1.key = e2.key; There is a great book that introduces SQL (SQL-1 and SQL-2 concepts) titled "The Practical SQL Handbook" (ISBN: 0-201-44787-8), which I've kept in my library since college. If you're in the mood, thumb through it.

I have a table employee. For each record in employee, I want to see if a record exists in table emp2 based on a field value in both tables. IE, for each employee for each emp2 if employee.field1 = emp2.field3 then do something interesting. end emp2 loop end employee loop. can someone point me to the right join syntax to get this done ? thanks, Darryl -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
