whit this query "update full_combin_random c set c.utilise=1 where c.ID in (select a.ID from full_combin_random a inner join full_combin b on b.utilise=1 and a.A=b.A and a.B=b.B and a.C=b.C and a.D=b.D and a.E=b.E and a.F=b.F);" or "select c.* from full_combin_random c where c.ID in (select a.ID from full_combin_random a inner join full_combin b on b.utilise=1 and a.A=b.A and a.B=b.B and a.C=b.C and a.D=b.D and a.E=b.E and a.F=b.F);" i have a infinity loop ! the table "full_combin_randon" contains + - 8000000 million rows, the table "full_combin" same thing. the two tables are indexed on fields (a, b, c, d, e, f) and (utilise). the processor goes up to 99%. I let the query run two days without results. -- 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 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
