Unknown column in 'field list' error on MySQL Update query

Question

I keep getting MySQL error #1054 when trying to perform this update query:

UPDATE MASTER_USER_PROFILE, TRAN_USER_BRANCH

SET MASTER_USER_PROFILE.fellow=`y`

WHERE MASTER_USER_PROFILE.USER_ID = TRAN_USER_BRANCH.USER_ID

AND TRAN_USER_BRANCH.BRANCH_ID = 17

It's probably some syntax error, but I've tried using an inner join instead and other alterations, but I keep getting the same message:

Unknown column 'y' in 'field list' 

Answer 1

Use different quotes for "y" as the identifier quote character is the backtick (“`”). Or else,  MySQL "thinks" that you point to a column named "y".
