Question

I’m using postgres and I’m getting the duplicate key error when updating a row:

cursor.execute("UPDATE jiveuser SET userenabled = 0 WHERE userid = %s" % str(userId))
psycopg2.IntegrityError: duplicate key value violates unique constraint "jiveuser_pk"

I don’t understand how updating a row can cause this error… any help will be much appreciated.

Answer 1

The error would seem to indicate that the userenabled column is participating in the jiveuser_pk primary key. My guess is that both userid and userenabled participate in the primary key, and that you’ve already a userid where userenabled is equal to zero.
