[SQL] getting duplicate number is there a

[Joel Fradkin]

I was using SET TRANSACTION ISOLATION LEVEL SERIALIZABLE in MSSQL.   Is there something similar in postgres to ensure its not in the middle of being updated?               sql = "SELECT COUNT(*) FROM tblcase WHERE LocationID = " & intLocationID & _                   " and substr(casenum,length(casenum)-1,2) = '" & right(year(date),2) & "' AND clientnum = '" & _                   chrClientNum & "'"   I will add a select just before doing the insert to see if this helps, its not happening a bunch, but 5 6 times a day is still an issue for me. I use the count as a segment of my case number so each time a new case is entered the count goes up for that location for that year.   Joel Fradkin   Wazagua, Inc. 2520 Trailmate Dr Sarasota, Florida 34243 Tel.  941-753-7111 ext 305   [EMAIL PROTECTED] www.wazagua.com Powered by Wazagua Providing you with the latest Web-based technology & advanced tools. © 2004.
