And always do the reload after a fresh start. No surprises that way ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, November 03, 2010 3:28 PM To: RBASE-L Mailing List Subject: [RBASE-L] - RE: SELECT counts
Thanks for the reply, Dennis. I will try that approach first. My database does get reloaded each day but it's getting fairly large with the RX2 at well over 4 GB. Have a great evening. -- Mike From: Dennis McGrath <[email protected]> To: [email protected] (RBASE-L Mailing List) Date: 11/03/2010 01:48 PM Subject: [RBASE-L] - RE: SELECT counts Sent by: [email protected] ________________________________ Reload the DB and see if the problem goes away. Corrupt indexes can cause this kind of anomaly.

I have a view that contains one "AS SELECT" query and one "UNION ALL SELECT" query. I encountered a puzzling situation with it when I queried for 2 CLM_ID values. CLM_ID is an INTEGER data type. The column is indexed. Example 1 gives an incorrect result using the "WHERE clm_id IN" statement. There are only 2 records but the command returns 3. Examples 2 through 5 are variations of the same statement and each one returns the correct answer. Why would Example 1 give an incorrect result? I triple checked the query to make sure it was logically correct. It was. Also puzzling is if I construct the view without the "UNION ALL SELECT" Example 1 returns the correct answer. Any thoughts? Mike Ramsour AK Steel Coshocton Works Example 1: Incorrect result SELECT COUNT(*) FROM reship_view WHERE clm_id IN (42723,42724) -- (Selecting or browsing shows 2 records for CLM_ID 42724) COUNT (*) ---------- 3 Example 2: SELECT COUNT(*) FROM reship_view WHERE clm_id IN (42724) COUNT (*) ---------- 1 Example 3: SELECT COUNT(*) FROM reship_view WHERE clm_id IN (42723) COUNT (*) ---------- 1 Example 4: SELECT COUNT(*) FROM reship_view WHERE clm_id = 42723 OR clm_id = 42724 COUNT (*) ---------- 2 Example 5: SELECT COUNT(*) FROM reship_view WHERE clm_id BETWEEN 42723 AND 42724 COUNT (*) ---------- 2 Confidentiality Notice This message is intended exclusively for the individual or entity to which it is addressed and may contain privileged, proprietary, or otherwise private information.
