select a.Name as PL_Name,b.Name as PC_Name,c.Name as PA_Name from
(select * from table1,table2 where table1.ID=table2.PL) a,
(select * from table1,table2 where table1.ID=table2.PC) b,
(select * from table1,table2 where table1.ID=table2.PA) c
where a.description=b.description

condition, I agree? It would return (size Table1)x(size Table2)^3 rows,
definitely not what Tariq wants. The query I supplied will return (size
Table2)x(1)^3 rows won't it? Or am I missing the point?
