Author RE: [PHP-DB] I have a query

if the tables have the same structure, use the union operator to query each
table separately and return it all in one result set

select * from asset1 where asset_loc='heaven'
union
select * from asset2 where asset_loc='heaven'
union
select * from asset3 where asset_loc='heaven'
union
select * from asset4 where asset_loc='heaven'
union
select * from asset5 where asset_loc='heaven'
