Re: Did NOT condition on VARCHAR change with 5.0.45?

`method` is the name of the column in the table.

In my opinion it should return every record from the table where `method` is
equal to NULL, ZERO or EMPTY STRING, as this table doesn't allow null, and
the field type is varchar, this would be EMPTY STRING's only.

This has always worked in the past. However now EVERY row is returned
regardless of the contents of `method`.

Thoughts?
