Hi, Apologies if this isn't the right place to ask - but I'm banging my head against the wall with this one! I'm trying to update a record in the table (creation script below) using the following SQL statement: UPDATE shop_customer SET eu_vat_number = "SK1234567890" AND vat_amount = 0 AND total_amount = 8.4925 WHERE customer_id = 7 AND hash="dcd5e751" Before running the query the value for eu_vat_number is 'null', vat_amount is 0.085 and total_amount = 8.5775. After I run the query (mysql_affected_rows = 1) the values for vat_amount and total_amount remain the same, but vat_number is changed to 0. I've been looking at this most of the afternoon, and it's probably something really simple but I just can't see it... Any ideas? Thanks in advance for your help...
