What you expect from this Badly written SQL??
The Problem is:-
1) Use of fuction based elimination of rows after joining.
Do you have Function Based Indexes??I don't think so.
2) Getting MAX(LENGTH(AGL_LOC_PREFIX)) and used that in
elimination of rows.
3) No Clear information Provided.
Explain Plan
Table Structures
Count For Each Table.
Stats Available or Not
Regards,
Rajat

Stats are up to date.
IS_M_AGREEMENT_LINE table contains 26450 records. others less than that.
no function based indexes.
