Try constructing a query that looks like this... select 't1' as source, t1.* from t1 where t1.list like "$criteria" union select 't2' as source, t2.* from t2 where t2.list like "$criteria" union select 't3' as source, t3.* from t3 where t3.list like "$criteria" union ... select 't24' as source, t24.* from t24 where t24.list like "$criteria" ; This query can be created by 1. storing all the table names in an array 2. constructing the individual select portion using array_map() 3. combining all individual selects using join($selects, 'union') -- Richard A.
