Wrong type for column value in partition definition
Production Risk
Low — the DDL fails; no table is created.
What this means
A partition boundary value has a type that does not match the corresponding COLUMNS partition column type.
Why it happens
- 1Specifying a string boundary value for an integer COLUMNS partition column.
- 2Type mismatch between partition boundary literals and column definitions.
How to reproduce
trigger — this will error
trigger — this will error
CREATE TABLE t (id INT)
PARTITION BY RANGE COLUMNS(id)
(PARTITION p0 VALUES LESS THAN ('ten')); -- string for INT columnexpected output
ERROR 1603 (HY000): Wrong type of column/partition value for partition function
Fix
Use boundary values matching the column type
Use boundary values matching the column type
CREATE TABLE t (id INT) PARTITION BY RANGE COLUMNS(id) (PARTITION p0 VALUES LESS THAN (10));
Why this works
Partition boundary values must be literals compatible with the corresponding partition column type.
