Maximum number of tables in join and left join

Hello everyone!

Does anybody knows which is the maximum number of tables that I can use in a join in DB2 (v9.5)?

I have to run a query with 25 tables and I know that in Oracle I can use only 6 in a join.

Note that particularly all of those tables have thousands (some of them hundreds) of rows..!

Thank you in advance,
Aggeliki

Search the online documentation for "SQL Limit". By the way, I think you are mistaken about Oracle allowing only 6 joined tables...
