Field type conversion question
I need to create a table that will store employees that attended certain events. I have two tables set up for this purpose. One (EmpTable) stores employee demographic information. The other (Events) stores information about the events (date, time, location, etc.) In EmpTable, the employee name is stored in fields FirstName and LastName. I would like to have a field in Events that will store multiple names with both fields from EmpTable concatenated into one string (i.e. FirstName LastName) What is the most efficient way to do this in MySQL?

One approach is an EventAttendance table that has two fields (eventnum, employeenum). Then multiple employees can attend one event, and there are no long strings running around. - Steve Yates - If you smoke after sex, you're doing it too fast. ~ Taglines by Taglinator - www.srtware.com ~ - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

RE: Field type conversion question
I would suggest having EmpTable (PRIMARY KEY=empID) EventsTable (PRIMARY KEY=eventID) AttendantsTable (PRIMARY KEY=[empID,eventID]) From there you can build queries to find persons who attended an event or which events a person went to.
