RE: SQL Question

Parameter markers are used with dynamic SQL.

Host fields for static.

Static performs better than dynamic.

If you can use static. Then I recommend you do so.

Subject: SQL Question

I have 2 files with a 1 to N relationship where I need to
select a common field from the 2nd file.
Since there is a 1 to N, I can not use SELECT INTO, but must
use SELECT with either DISTINCT or GROUP BY.
The selection criteria will vary every time I need to select
this data.
Is it better to use the host fields in the SELECT statement
WHERE clause, or to use Parameter Markers and put the host
fields in the OPEN statement?

Thanks,
