Description
This script returns an error unexpectedly:
DROP TABLE IF EXISTS t1; |
CREATE TABLE t1 ( |
c1 BIGINT UNSIGNED, |
c2 BIGINT UNSIGNED |
);
|
INSERT INTO t1 VALUES (20030516235329,20000127231341); |
SELECT c2-c1 FROM t1; |
ERROR 1690 (22003): BIGINT UNSIGNED value is out of range in '(`test`.`t1`.`c2` - `test`.`t1`.`c1`)'
|
It tries to create a BIGIN UNSIGNED column as a result:
DROP TABLE IF EXISTS t2; |
CREATE TABLE t2 AS SELECT c2-c1 FROM t1 LIMIT 0; |
SHOW CREATE TABLE t2; |

|
| t2 | CREATE TABLE `t2` (
|
`c2-c1` bigint(21) unsigned DEFAULT NULL
|
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
|

|
The choice beween BIGINT and UNSIGNED BIGINT is controlled by the NO_UNSIGNED_SUBTRACTION flag in sql_mode.
There should probably be a way to create a DECIMAL column instead.
