SQL Optimizer and LF with *OMIT fields

[GKern@xxxxxxxxxxxxxxxx]

A co-worker just showed me a problems she's having. She has an LF that has 
*OMIT fields specified to reduce the size of the number of available 
entries in the file. The LF is used in an embedded ILE RPG program, that 
has a "select * from my_LF where insurance_company <> nnn" statement.

In a debug session she noticed that the optimizer chose to do its own 
thing and it read over the entire physical file, and included records that 
were supposed to be ignored (via the *OMIT) specified for the LF. 

So the program is suspect as to the integrity of what SQL will actually 
select. We have a few other programs that use this technique and to my 
knowledge haven't had any other problems of a similar nature.

So.... Is there any way to override the query optimizer so that it will 
always use the actual file/lf specified in the select statement?

Thanks!
