RE: Did NOT condition on VARCHAR change with 5.0.45?

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`.

Although it doesn't matter here because of the NOT NULL, this will never match NULL values. NULL values are neither true nor untrue, so they have to be checked with IS NULL. This is standard, not a MySQL thing. - Perrin -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

`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? What is method mean in your sql statement?
