<p>MySQL Error 1480: ER_PARTITION_WRONG_VALUES_ERROR occurs when a table partition uses a VALUES clause incompatible with the selected partition type. Align the VALUES syntax with the correct partitioning method (e.g., RANGE, LIST) or switch the partition type to resolve the issue.</p>
Only %s PARTITIONING can use VALUES %s in partition
MySQL raises ER_PARTITION_WRONG_VALUES_ERROR when you create or alter a table with partitioning syntax that mixes an invalid VALUES clause with the chosen partitioning method. The error text Only %s PARTITIONING can use VALUES %s in partition signals that the VALUES expression you provided matches a different partitioning scheme.
The server halts the statement to prevent inconsistent partition metadata that would corrupt query routing and index pruning. Fixing the clause restores reliable data access.
The error shows up during CREATE TABLE, ALTER TABLE, or EXCHANGE PARTITION statements that specify RANGE, LIST, HASH, or KEY partitioning. It usually surfaces immediately after the VALUES keyword because MySQL validates the clause against the declared partition type.
Developers commonly encounter it while converting RANGE partitions to LIST or when copying partition syntax from other databases that support different keywords.
An invalid partition definition blocks table creation or schema migration, halting deployments and CI workflows. Leaving the issue unresolved delays feature launches, causes downtime during releases, and forces workarounds like full-table scans instead of partition pruning.
Correct partition syntax ensures predictable query plans, faster analytics, and efficient storage management in production environments.
Incompatible VALUES keyword usage is the primary trigger. RANGE partitions expect VALUES LESS THAN while LIST partitions expect VALUES IN. HASH and KEY partitions do not accept any VALUES clause at all.
Using VALUES LESS THAN with LIST partitioning or VALUES IN with RANGE partitioning instantly throws Error 1480. Copy-pasting sample code without adapting it to the right partitioning type is the usual culprit.
First, confirm the partitioning method you need based on the data distribution logic. Then adjust the VALUES clause to the correct syntax or remove it for HASH and KEY types.
If the clause is correct but the partition type is wrong, switch the PARTITION BY clause to RANGE, LIST, HASH, or KEY to match the VALUES expression. Always test the DDL in a staging database before running in production.
Scenario: Using RANGE partitions with VALUES IN. Solution: Change VALUES IN to VALUES LESS THAN or convert the partitioning type to LIST.
Scenario: Adding a VALUES clause to HASH partitioning. Solution: Remove the VALUES line entirely because HASH and KEY do not support it.
Keep a template library of validated partition DDL examples in Galaxy Collections so your team reuses the correct syntax.
Automate schema linting with CI checks that parse CREATE TABLE statements and flag unsupported VALUES clauses before merge.
Error 1493 partition constant out of range: occurs when VALUE boundaries exceed column limits; fix by adjusting boundary numbers.
Error 1494 partition column list too long: happens when the number of partitioning columns exceeds the allowed count; reduce column list.
Error 1503 failed to add partition: appears on ALTER TABLE when disk space or metadata limits prevent partition creation; ensure space and privileges.
Using VALUES IN inside RANGE partitioning or VALUES LESS THAN inside LIST partitioning triggers the error immediately.
HASH and KEY methods do not accept any VALUES clause; including one raises Error 1480.
Developers often copy partition DDL from blogs written for a different database version or partitioning method, leading to wrong VALUES clauses.
ORMs or migration tools that auto-generate partitions based on configuration flags may insert the wrong VALUES syntax for the target table.
Raised when a partition boundary is outside the column domain. Adjust boundary values or column definitions.
Occurs when the number of columns in the partition key exceeds the allowed limit. Reduce columns or use a composite key.
Thrown when MySQL fails to create a partition, often due to storage limits or missing privileges. Check disk space and user rights.
No. A single table can only use one partitioning method. Mixing VALUES IN and VALUES LESS THAN violates partition rules and triggers Error 1480.
No. MySQL 8.0 retains the same VALUES LESS THAN and VALUES IN clauses. The error rules are identical to MySQL 5.7.
Error 1480 is unrelated to the partition count. It focuses solely on the VALUES clause. Partition limits are governed by other variables like max_partitions.
Galaxy's AI copilot suggests the correct VALUES clause based on the chosen partition type and flags mismatches in real time, preventing Error 1480 before execution.
