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

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'
Solution

  • Try using different quotes for "y" as the identifier quote character is the backtick (`). Otherwise MySQL "thinks" that you point to a column named "y".

    See also MySQL 8 Documentation

    Please use double-/single quotes for values, strings, etc. Use backticks for column-names only.
