hanging query for 2.5 --------------------- Key: CORE-5412 URL: http://tracker.firebirdsql.org/browse/CORE-5412 Project: Firebird Core Issue Type: Bug Components: ISQL Affects Versions: 2.5.6 Environment: Firebird Linux 2.5.2 Reporter: Ray Holme
I was running a query looking for the range of a problem. select invoice_id, datetime from invoices where invoice_id in (select min(invoice_id) from invoice_lines where srv_order is null) or invoice_id in (select max(invoice_id) from invoice_lines where srv_order is null); After returning the first row (min) the query hangs. So I tried: select invoice_id, datetime from invoices where invoice_id in (select max(invoice_id) from invoice_lines where srv_order is null); This too hangs and never retrurns (well I did not wait more than 1 minute). But running this query returns results fine immediately. select max(invoice_id) from invoice_lines where srv_order is null; and the following amended query works fine. ( supplying the min and max values) explicitly) select invoice_id, datetime from invoices where invoice_id in (5, 11284); I could create a version of the DB for you. I do NOT believe you will need this as the problem is I(MHO) related to the select max hanging in a sub-query. Note that this is an active DB (open by an inactive webapp - this should not matter, but ....) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tracker.firebirdsql.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
