EXAMPLES
TINYTEXT
Example of TINYTEXT:
CREATE TABLE tinytext_example (
description VARCHAR(20),
example TINYTEXT CHARACTER SET latin1
) DEFAULT CHARSET=latin1; -- One byte per char makes the examples clearer
INSERT INTO tinytext_example VALUES
('Normal foo', 'foo'),
('Trailing spaces foo', 'foo '),
('NULLed', NULL),
('Empty', ''),
('Maximum', RPAD('', 255, 'x'));
SELECT description, LENGTH(example) AS length
FROM tinytext_example;
+---------------------+--------+
| description | length |
+---------------------+--------+
| Normal foo | 3 |
| Trailing spaces foo | 9 |
| NULLed | NULL |
| Empty | 0 |
| Maximum | 255 |
+---------------------+--------+
Data Too Long
When a value exceeds the size of one of the TEXT data type, the value is silently truncated.
Example of data too long behavior for TINYTEXT:
TRUNCATE tinytext_example;
INSERT INTO tinytext_example VALUES
('Overflow', RPAD('', 256, 'x'));
SELECT description, LENGTH(example) AS length
FROM tinytext_example;
+-------------+--------+
| description | length |
+-------------+--------+
| Overflow | 255 |
