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_mode=STRICT_TRANS_TABLES (the default) is set, an out-of-range value generates an error. If strict mode is not in effect, the value is rounded to the nearest valid value without any warnings.

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 */
