I have a bit of an odd problem with an update statement. I have a table logs2 at 35 columns wide and a miserly 193 rows. I also have a table testtime at 4 columns wide and 2.2 million rows. When I run the following sql I get a success on testtime and a failure of "pqReadData() -- backend closed the channel unexpectedly on logs2". update <either tablename> set time2 = to_timestamp(time, 'HH24:MI:SS'); This is quite confusing to me, I have a success on updating a 2.2 million row table and a failure on a 193 row table (the smaller data set is a subset of the 2.2 million row selection). Both tables are fresh, built with a select into statement, a variety of other queries work fine with these tables. The machine has a gig of ram and a 800mb shared buffer. The sort buffer set to 16mb. What is causing this problem? How can I figure this out? I have some theories on what might be going wrong. The sort buffers are probably too small (I am working on getting my hands on the root password so I can play with this). There is some problem with version 7.0.3 that is causing the back end to drop out, but I have seen no postings on that possibility. So any advice on how to trace this problem down would be great. -Jeff Barrett ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
