RE: SQL embeded in RPG with passed parameters won't use indexes

Hello,

my experience with SQL optimizer is that I must use exactly matching data 
types/formats in where, join etc clauses so that SQL optimizer makes use of 
indexes I have defined. In Your situation, SQL cannot use indexes as the format 
of numerics You provide are wider I suppose.

What errors do You get when passing 7P,0 params?? How do You pass them to the 
program?

Hi,
DTMV95 has 7P 0, I originally defined startdate and enddate as 7P 0 but got
many strange errors when I passed in the parameters, they seemed to be
getting corrupted somehow?

Hello,

what data format does DTMV95 column have? It ought to be 15P 5 I guess if
host vars are 15P 5...
