Description
SET sql_mode=STRICT_ALL_TABLES; |
DROP TABLE IF EXISTS t1, t2; |
CREATE TABLE t1 (a TINYINT); |
INSERT INTO t1 VALUES (-1); |
CREATE TABLE t2 AS SELECT a, HEX(a) AS h FROM t1; |
ERROR 1406 (22001): Data too long for column 'h' at row 1
|
Looks wrong.
This script:
CREATE TABLE t2 AS SELECT a, HEX(a) AS h FROM t1 LIMIT 0; |
SHOW CREATE TABLE t2; |
demonstrates that the data type for the column h is too short:
+-------+--------------------------------------------------------------------------------------------------------------------------------------------+
|
| Table | Create Table |
|
+-------+--------------------------------------------------------------------------------------------------------------------------------------------+
|
| t2 | CREATE TABLE `t2` (
|
`a` tinyint(4) DEFAULT NULL,
|
`h` varchar(8) CHARACTER SET utf8 DEFAULT NULL
|
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
|
+-------+--------------------------------------------------------------------------------------------------------------------------------------------+
|
It should be varchar(16) to fit hex representation of positive completents for negative numbers:
SELECT a, HEX(a) FROM t1; |
+------+------------------+
|
| a | HEX(a) |
|
+------+------------------+
|
| -1 | FFFFFFFFFFFFFFFF |
|
+------+------------------+
