Description:
Running this SQL to update all rows in a table:

update [table]
  set [column] = [somevalue]

...causes this error:

Error Code: 1242
Subquery returns more than 1 row

This prevents the SQL command from executing. It happens when using both the command line client and workbench.

I tried it on a MySQL server running on Windows using the same schema and command, and it works properly.

How to repeat:
try to update all rows in a table on OS X

i wouldn't say this is a bug.  check that you don't have some incorrectly written triggers on these tables being updated?

Oooof! You are correct. I removed the update trigger and the query worked. 

Sorry!
