Hi Bill,

This fix works in principle. It still doesn't work for my date field though. 
Let me explain. I used to have a problem with another bcp row later in the 
code. This field had a value of NULL and it was failing for the same reason. 
I could reach that position I changed the #trans_bcp table definition column 
trans_date to be from datetime to char(30 so it bypassed the date field 
column. It works now after the fix.

However, if I revert my #trans_bcp column definition to datetime then I get a 
different error see below... The value is still NULL when I am expecting it 
to be not null, so it fails.

Just a general question, when you pass dates what's the length I need to 
define my C structure for all date fields? Maybe this is where it goes wrong. 

If the error below tells you something then let me know, otherwise, I will do 
some further tests in case there is something else wrong with the code. In a 
way I have a workaround now.

Thanks very much.

Panos
