RE: SQL select by date

["Ken Slaugh" <ken.slaugh@xxxxxxxxxx>]

Try...

DATE(VARCHAR(POSTMM) || '/' || VARCHAR(POSTDD) || '/' || VARCHAR(POSTCY)) AS
POSTDATE 

... You should be able to refer to POSTDATE in the WHERE clause and/or ORDER
BY.

HTH, Ken

Subject: SQL select by date

Hi,

I want to select some records via SQL that contain a transaction posting
date via a date range.  Unfortunately, the dates are stored in
components: 

POSTCY  4,0
POSTMM  2,0
POSTDD  2,0

In order to do a range selection in a where clause, the date fields must be
concatenated together in some way.

This file has millions of records, and there is an index by POSTYY, POSTMM,
POSTDD.

What is the correct (efficient) way that will hopefully use the existing
index?  

Thanks.
