Hi,
Tested again with FB 2.5.1 & FB 2.5.5, apparently, this is not a problem from
FB 3.0, but it was already appeared since FB 2.5.
Same machine, database, query & engine, SC FB 2.5.1 & SC FB 2.5.2 runs a lot
faster than FB 2.5.5 & FB 3.0.
Regards,
Anton
FB 2.14 - Delphi 2007 - IBDAC TIBCScript
Although I'm certain this is not a Delphi problem, I've included a copy of the
commands used to create the SQL. Those commands work in FlameRobin, and in
IBExpert. I used both to create working DDL, which I copied into my delphi
program. Any help or

This is just a different output for select from procedure GET_STCK, v3.0
does not show all its internals as v2.5 did.
You'd better compare per table performance counters

Hi,
This is the Query plan from SS FB 3.0
PLAN (GET_STCK NATURAL)
and here is the Query plan from SC FB 2.5.2
PLAN (G_T3 NATURAL)(M_TT INDEX (RDB$PRIMARY2))(A INDEX (IDX_M_GD3))(A INDEX
(IDX_M_GD3))SORT (JOIN (B INDEX (TM_D), A INDEX (T2_T1), C INDEX
(RDB$PRIMARY25), D INDEX (RDB$PRIMARY21),
Hi,
About Db cache, found the problem. Now I could set Db Cache per database at 2
GB (16384 x 131072), try to set at 4GB (16384 x 262144), no error on gfix, but
it just crashed when tried to connect, no error message shown.
Regards,
Anto.
Hi,
1. will be good to see this query plans
2. will be good to see exact error message
3. also check your db by gfix –validate –full

c.id from
