Hello,
I'm trying to optimize a request and cannot explain what I observe.
I have a relatively simple request using 3 tables returning around 1.8M

Did you tried with firebird 2.5.x on it

firebird log should contain the error
great thanks

AND (Table3.ComputationID = 9)
ORDER BY Table1.ID ASC;
I'd welcome any insight as to what I might be doing wrong.
