Hi Roland, Is the query producing right results in the first place?
If there are n tables in the FROM clause, there must be atleast n-1 joins in the where clause to avoid the Cartesian product (which definitely screws up performance and rarely produces correct results.) In the FROM clause of your query, there are 6 tables, whereas in the WHERE clause there is only 1 join condition. HTH.

I am wondering why this query takes so long time, Do I need more conditions to make it run, or it it just that this query take so long time to run? Anything wrong with the query? Please help me with this.
