<p>MySQL raises ER_PARTITION_COLUMN_LIST_ERROR when the column lists used in individual partition definitions do not exactly match the list defined in the PARTITION BY clause.</p>
<p>MySQL Error 1653: ER_PARTITION_COLUMN_LIST_ERROR arises when column lists differ between the PARTITION BY clause and individual VALUES clauses. Align every VALUES list with the partition expression to resolve the inconsistency.</p>
Inconsistency in usage of column lists for partitioning
MySQL throws error code 1653 when it detects mismatched or missing column lists in a PARTITION BY RANGE COLUMNS or LIST COLUMNS definition. Every VALUES clause must reference exactly the same columns, in the same order, as the partition expression.
The error surfaces during CREATE TABLE, ALTER TABLE, or EXCHANGE PARTITION statements if one partition omits the column list or specifies a different column count. It also triggers when VALUES LESS THAN or VALUES IN literals do not align with the declared column list.
MySQL rejects the entire DDL statement when this inconsistency exists, blocking table creation or schema changes. Correct partitioning guarantees accurate data placement, efficient pruning, and simpler maintenance.
One partition lists two columns while others list one, causing MySQL to flag the mismatch.
Leaving out column values in a partition definition breaks alignment with the partition expression.
Switching between single and composite literals within the same table definition triggers the error.
Supplying column values in a different sequence from the PARTITION BY clause also causes the inconsistency.
Raised when a non-deterministic function is used in a partitioning expression.
Occurs when VALUES LESS THAN ranges are not strictly increasing.
Triggered when a partition constant is outside the permitted domain.
Similar naming but focuses on range ordering, not column list mismatch.
No. A table must use one partitioning method. Mixing methods results in syntax errors.
Yes, both engines validate partition column lists and issue comparable errors.
Galaxy's real-time linting flags mismatched VALUES lists, letting you correct them before running the statement.
Properly aligned lists incur no extra cost. Performance depends on partition pruning and query filters.
