pro_php thread: MySQL PRIMARY KEY SELECT statement

Hi Joel,

What do you mean by "transferrable to a table with a key based on one
column"?

It seems to me that you just need to:
UPDATE mytable SET value1 = 'somevalue', value2 = 'someothervalue' WHERE
PRIMARYKEYFIELD1 ='something' AND PRIMARYKEYFIELD2='something2';
