TEXT
Example of TEXT:
CREATE TABLE text_example (
description VARCHAR(20),
example TEXT
) DEFAULT CHARSET=latin1; -- One byte per char makes the examples clearer
INSERT INTO text_example VALUES
('Normal foo', 'foo'),
('Trailing spaces foo', 'foo '),
('NULLed', NULL),
('Empty', ''),
('Maximum', RPAD('', 65535, 'x'));
SELECT description, LENGTH(example) AS length
FROM text_example;
+---------------------+--------+
| description | length |
+---------------------+--------+
| Normal foo | 3 |
| Trailing spaces foo | 9 |
| NULLed | NULL |
| Empty | 0 |
| Maximum | 65535 |
+---------------------+--------+
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 TEXT:
TRUNCATE text_example;
INSERT INTO text_example VALUES
('Overflow', RPAD('', 65536, 'x'));
ERROR 1406 (22001): Data too long for column 'example' at row 1
