EXAMPLES
SIGNED and UNSIGNED
The INT data type may be SIGNED (allowing negative values) or UNSIGNED (not allowing negative values).
Example of INT SIGNED (the default):
CREATE TABLE int_signed_example (
description VARCHAR(20),
example INT SIGNED
);
INSERT INTO int_signed_example VALUES
('Zero', 0),
('Forty-Two', 42),
('Minimum', -2147483648),
('Maximum', 2147483647);
Example of INT UNSIGNED:
CREATE TABLE int_unsigned_example (
description VARCHAR(20),
example INT UNSIGNED
);
INSERT INTO int_unsigned_example VALUES
('Zero', 0),
('Forty-Two', 42),
('Minimum', 0),
('Maximum', 4294967295);
Out-of-Range
A value is considered "out-of-range" when it is too small or too large to be stored in a data type.
When sql_
An example of non-strict out-of-range behavior:
TRUNCATE int_signed_example;
-- Disable strict mode or the inserts will fail
SET sql_mode=(SELECT REPLACE(@@sql_mode, 'STRICT_TRANS_TABLES', ''));
INSERT INTO int_signed_example VALUES
('Underflow', -2147483649),
('Overflow', 2147483648);
SELECT * FROM int_signed_example;

| description | example |
+-------------+-------------+
| Underflow | -2147483648 |
| Overflow | 2147483647 |
+-------------+-------------+
TRUNCATE int_unsigned_example;
-- Disable strict mode or the inserts will fail
SET sql_mode=(SELECT REPLACE(@@sql_mode, 'STRICT_TRANS_TABLES', ''));
INSERT INTO int_unsigned_example VALUES
('Underflow', -1),
('Overflow', 4294967296);
SELECT * FROM int_unsigned_example;
+-------------+------------+
| description | example |
+-------------+------------+
| Underflow | 0 |
| Overflow | 4294967295 |
+-------------+------------+
INT ZEROFILL
While Xpand accepts the INT ZEROFILL type on table create, the qualifier is ignored and silently dropped:
CREATE TABLE int_zerofill_example (
description VARCHAR(20),
example INT ZEROFILL
);
SHOW CREATE TABLE int_zerofill_example\G
*************************** 1. row ***************************
Table: int_zerofill_example
Create Table: CREATE TABLE `int_zerofill_example` (
`description` varchar(20) CHARACTER SET utf8,
`example` int(11)
) CHARACTER SET utf8 /*$ SLICES=3 */
