You need to separate the SET arguments with commas, not ANDs...
It's really doing something like this:
UPDATE shop_customer SET eu_vat_number = ("SK1234567890" AND vat_amount = 0
AND total_amount = 8.4925) WHERE customer_id = 7 AND hash="dcd5e751"
("SK1234567890" AND vat_amount = 0 AND total_amount = 8.4925) evaluates to
false (0) , so that's what gets set.

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...
Cheers,
Kev
