+#  If the column can take NULL as a value, the column is defined with an
+#  explicit DEFAULT NULL clause. This is the same as before 5.0.2.
+#
+#  If the column cannot take NULL as the value, MySQL defines the column with

+#  statement includes no value for the column, MySQL handles the column
+#  according to the SQL mode in effect at the time:
+#
+#    * If strict SQL mode is not enabled, MySQL sets the column to the
+#      implicit default value for the column data type.
+#
+#    * If strict mode is enabled, an error occurs for transactional tables and
+#      the statement is rolled back. For non-transactional tables, an error
+#      occurs, but if this happens for the second or subsequent row of a
+#      multiple-row statement, the preceding rows will have been inserted.
