Re: Kindly help.

Hi Ian and Chetan,

There is a new HOw-TO type guide on the site which might also be useful,
if you've got SQL Server 7. It uses the tools which come with SQL
Server 7 and seems very straightforward, but I haven't had any feedback
regarding it.

Regards and best wishes,

Another possible cause for it doing that is that you have a text field with carriage returns in it which are leading psql to believe it has hit the end of a record. I think the only way to fix this is to replace them with \\n (as opposed to \n). The problem with that is that you have real line breaks to specify the end of a record. What I did was to specify something other than a CR as a record delimiter (in my case ~) then replace all \n with \\n, then replace all ~ with \n. There may be a simpler way, but I don't know what it is.
