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 MEDIUMBLOB:
TRUNCATE mediumblob_example;
INSERT INTO mediumblob_example VALUES
('Overflow', RPAD('', 16777216, CHAR(7)));
ERROR 1406 (22001): [7177] Data truncation: Data too long for column "example"
