Q: 

How to get information about used tables from processed query?

Hi,

Previous programmer left me with "beautiful" piece of code and he kind of forgot to apply something to it. There is a query which selects several items from several tables.

6 Items can be chosen. It means 6 tables can be chosen, however there can be more tables - even 20 of them. I need to get that list of tables from processed query.

Indeed, is it possible at all? Is there any command to get a list of tables the query used?

+1  A: 

I'm unsure if I am understanding the question correctly but it may be worth 'explaining' the query and seeing which tables are being used as below.

EXPLAIN SELECT * FROM table1 JOIN table2 USING (id)
