Hello all.I have a temp table called #JOB which i know contains data (i can select from it and it shows about 30 rows). The problem is when i am trying to update another table with the contents of the temp table...........query analyser tells me no rows have been updated. here is the code i am using:UPDATE JOB SET JOB.JOB_REF = #JOB.JOB_REF FROM #JOB Does anyone have any ideas where i am going wrong? Cheers in advance. |

| [code]Update jSet Job_Ref = t.Job_refFrom Job j Join #Job t on j.id = t.id[/code]Note: I am assuming ID as Primary Key column here (common joining field).Harsh AthalyeIndia."The IMPOSSIBLE is often UNTRIED" |

| Are you trying to insert these records? If you're updating a table, it has to be present in the FROM clause of the statement. This would require you to join JOB to #JOB. However, since you're updating the joining key, this would be problematic!Mark |
