Thanks for the replies.
I checked out the latest CVS and the fix is there.
I had the release version which didn't have the updated code.
My code is virtually the same as the example in the link in my message, this can be used as a test.

Thanks again.

And my bcp_bind documentation says:
"It is an error to call bcp_columns when using bcp_bind."
Funny, there's no unit test for bcp_bind. Hmph.
Mohammed, a quick check of the CVS code confirms what Bill says, that
bcp_init() sets things up correctly. Rather than a log, could you just
send a little test case that demonstrates the problem? I'd like to add it
to our unit tests once the problem is solved, one way or the other.
