    If you update a column that has been declared , an error occurs if strict SQL mode is enabled; otherwise, the column is set to the implicit default value for the column data type and the warning count is incremented.

    The implicit default value is tables for which there are foreign key constraints, the My SQL optimizer might process tables in an order that differs from that of their parent/child relationship. Instead, update a single table and rely on the provides to cause the other tables to be modified accordingly. COLUMN2 IS NULLAn outerjoin is performed based on the equijoin condition.

    (This is because the order in which the rows are updated determines which rows are ignored.) With this change, such statements produce a warning in the log when using statement-based mode and are logged using the row-based format when using mode.

    Without the WHERE clause, rows that do not have a corresponding row in SQL.
