Steps to reproduce

  1. Type an UPDATE query against a table, setting some column to NULL and the WHERE condition actually match some rows. In my case, UPDATE api_keys SET fileid=NULL WHERE fileid='';
  2. Simulate the query
  3. phpMyAdmin shows 0 rows affected while simulating, upon investigating the SELECT query used in the simulation, I found "<> NULL", which is believed to be the cause of matching nothing.
  4. Run the query, and see rows updated != 0

Expected behaviour

Matched rows > 0

Actual behaviour

Matched rows == 0
