Du kan prova att antingen GÅ MED dem (Länka ihop dem) eller använda UNION (Kombinera två val i ett);

select a.col1, b.col1
from table1 a
inner join table2 b on a.id = b.id;
http://dev.mysql.com/doc/refman/5.0 /sv/union.html
select name as col1, surname as col2 from table1
union
select location as col1, desc as col2 from table2;
