Data too long

When SQL_MODE is strict (the default) a value is considered "too long" when its length exceeds the size of the data type, and an error is generated.

Example of data too long behavior for MEDIUMTEXT:

TRUNCATE mediumtext_example;

INSERT INTO mediumtext_example VALUES
  ('Overflow', RPAD('', 16777216, 'x'));
ERROR 1406 (22001): Data too long for column 'example' at row 1
