These queries work fine:

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFF AS UNSIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFF AS UNSIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFF AS UNSIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFF AS UNSIGNED);

There queries return an error:

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFF AS UNSIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFFFF AS UNSIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFFFFFF AS UNSIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFFFFFFFF AS UNSIGNED);

ERROR 1264 (22003): Out of range value for column 'CAST(0xFFFFFFFFFF AS UNSIGNED)' at row 1

Adding LIMIT 0 helps to create the table and see what's the problem:

CREATE OR REPLACE TABLE t1 AS

SELECT

  CAST(0xFFFFFFFFFF AS UNSIGNED),

  CAST(0xFFFFFFFFFFFF AS UNSIGNED),

  CAST(0xFFFFFFFFFFFFFF AS UNSIGNED),

  CAST(0xFFFFFFFFFFFFFFFF AS UNSIGNED) LIMIT 0;

DESCRIBE t1;

+--------------------------------------+-----------------+------+-----+---------+-------+

| Field                                | Type            | Null | Key | Default | Extra |

+--------------------------------------+-----------------+------+-----+---------+-------+

| CAST(0xFFFFFFFFFF AS UNSIGNED)       | int(5) unsigned | NO   |     | NULL    |       |

| CAST(0xFFFFFFFFFFFF AS UNSIGNED)     | int(6) unsigned | NO   |     | NULL    |       |

| CAST(0xFFFFFFFFFFFFFF AS UNSIGNED)   | int(7) unsigned | NO   |     | NULL    |       |

| CAST(0xFFFFFFFFFFFFFFFF AS UNSIGNED) | int(8) unsigned | NO   |     | NULL    |       |

+--------------------------------------+-----------------+------+-----+---------+-------+

Notice, it creates too small columns. All hex hybrids with more than 8 hexadecimal digits should create BIGINT columns.

The same problem is repeatable for SIGNED type cast:

These queries work fine:

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFF AS SIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFF AS SIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFF AS SIGNED);

These queries return the same error:

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFF AS SIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFF AS SIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFFFF AS SIGNED);

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFFFFFF AS SIGNED);

ERROR 1264 (22003): Out of range value for column 'CAST(0xFFFFFFFFFFFFFF AS SIGNED)' at row 1

This query works fine again:

CREATE OR REPLACE TABLE t1 AS SELECT CAST(0xFFFFFFFFFFFFFFFF AS SIGNED);
