EXAMPLES
SIGNED and UNSIGNED
The BIGINT data type may be SIGNED (allowing negative values) or UNSIGNED (not allowing negative values).
Example of BIGINT SIGNED (the default):
CREATE TABLE bigint_signed_example (
description VARCHAR(20),
example BIGINT SIGNED
);
INSERT INTO bigint_signed_example VALUES
('Zero', 0),
('Forty-Two', 42),
('Minimum', -9223372036854775808),
('Maximum', 9223372036854775807);
Example of BIGINT UNSIGNED:
CREATE TABLE bigint_unsigned_example (
description VARCHAR(20),
example BIGINT UNSIGNED
);
INSERT INTO bigint_unsigned_example VALUES
('Zero', 0),
('Forty-Two', 42),
('Minimum', 0),
('Maximum', 18446744073709551615);
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 bigint_signed_example;
-- Disable strict mode or the inserts will fail
SET sql_mode=(SELECT REPLACE(@@sql_mode, 'STRICT_TRANS_TABLES', ''));
INSERT INTO bigint_signed_example VALUES
('Underflow', -9223372036854775809),
('Overflow', 9223372036854775808);
SELECT * FROM bigint_signed_example;

TRUNCATE bigint_unsigned_example;
-- Disable strict mode or the inserts will fail
SET sql_mode=(SELECT REPLACE(@@sql_mode, 'STRICT_TRANS_TABLES', ''));
INSERT INTO bigint_unsigned_example VALUES
('Underflow', -1),
('Overflow', 18446744073709551616);
SELECT * FROM bigint_unsigned_example;

| description | example |

| Underflow | 0 |
| Overflow | 18446744073709551615 |

BIGINT ZEROFILL
While Xpand accepts the BIGINT ZEROFILL type on table create, the qualifier is ignored and silently dropped:
CREATE TABLE bigint_zerofill_example (
description VARCHAR(20),
example BIGINT ZEROFILL
);
SHOW CREATE TABLE bigint_zerofill_example\G
*************************** 1. row ***************************
Table: bigint_zerofill_example
Create Table: CREATE TABLE `bigint_zerofill_example` (
`description` varchar(20) CHARACTER SET utf8,
`example` bigint(20)
) CHARACTER SET utf8 /*$ SLICES=3 */
