Selecting rows with condition on two columns together i have table with columns
Number and VAT
How can i select all rows without row which is Number=123 and VAT=15 ?
I tried something like this

SELECT * FROM tablex WHERE &lt;.. zilions of conditions..&gt; AND (Number=123 AND VAT!=15)


But it does not work, i need every rows and with Number 123 too but not in case if VAT is 15.
Any idea ? Thank you
then u can use this one  

SELECT * FROM tablex WHERE Number&lt;>123 OR VAT&lt;>15
