Description

MariaDB Error 1567 indicates that a SQL statement has referenced a partition name that does not exist for the specified table or is syntactically incorrect. This error commonly arises when performing operations like altering, dropping, or selecting data from specific partitions in a partitioned table.

Error Message

Incorrect partition name

🔍

Known Causes

4 known causes

⚠️

Referring to a Non-Existent Partition

This occurs when a SQL statement attempts to access, modify, or drop a partition using a name that is not defined for the table.

⚠️

Typographical Error or Case Mismatch

A simple spelling mistake or incorrect casing in the partition name within your SQL query can lead to this error, as partition names might be case-sensitive depending on the operating system and server configuration.

⚠️

Table is Not Partitioned

Attempting to use partition-specific SQL commands (e.g., `ALTER TABLE ... DROP PARTITION`) on a table that has no partitions defined will result in this error.

⚠️

Incorrect Partition Type Reference

The error can occur if you try to reference a subpartition as a main partition, or vice-versa, or if the partition name belongs to a different partitioning scheme than expected.

Solutions

4 solutions available

1. Verify Partition Name in Your Query easy

Double-check that the partition name used in your SQL query exactly matches an existing partition.

1

Identify the SQL statement that is causing the error (e.g., INSERT, UPDATE, DELETE, SELECT).

2

Examine the query for any explicit references to a partition name. This often appears in `PARTITION (...)` syntax.

SELECT * FROM your_table PARTITION(non_existent_partition) WHERE id = 1;

3

List all partitions for the table to confirm the correct names. Replace `your_table` with your actual table name.

SHOW PARTITIONS FROM your_table;

4

Correct the partition name in your SQL query to match one of the names returned by `SHOW PARTITIONS`.

SELECT * FROM your_table PARTITION(correct_partition_name) WHERE id = 1;

2. Remove Explicit Partition Reference if Unnecessary easy

If your query doesn't need to target a specific partition, remove the explicit `PARTITION (...)` clause.

1

Locate the SQL query that is failing.

2

Check if the query explicitly specifies a partition using the `PARTITION (...)` syntax.

INSERT INTO your_table PARTITION(some_partition) (col1, col2) VALUES (1, 'a');

3

Remove the `PARTITION (...)` clause from the query. MariaDB will automatically select the correct partition based on the partitioning scheme and the data being inserted/queried.

INSERT INTO your_table (col1, col2) VALUES (1, 'a');

3. Recreate Partition if Name is Typo or Incorrectly Defined medium

If a partition name was mistyped during definition or is no longer valid, recreate it.

1

First, verify the existing partition names using `SHOW PARTITIONS FROM your_table;`.

SHOW PARTITIONS FROM your_table;

2

Identify the partition that is causing the error. This might be due to a typo during its creation or a change in the partitioning scheme.

3

If the partition name is indeed incorrect or non-existent, you'll need to drop the incorrect one (if it exists but is malformed) or proceed to add a new one.

-- Example: If 'wrong_partition_name' exists but is problematic
DROP PARTITION wrong_partition_name FROM your_table;

4

Define and add the correct partition. This example assumes RANGE partitioning. Adjust the `VALUES LESS THAN` or `FOR VALUES IN` clause according to your partitioning type.

ALTER TABLE your_table ADD PARTITION (PARTITION correct_partition_name VALUES LESS THAN (100));

5

After recreating the partition, re-run the query that was previously failing.

4. Inspect Partitioning Scheme for Consistency advanced

Thoroughly review your table's partitioning definition to ensure all partition names are valid and consistent.

1

Retrieve the `CREATE TABLE` statement for your partitioned table.

SHOW CREATE TABLE your_table;

2

Carefully examine the `PARTITION BY` clause and the subsequent `PARTITIONS` definition.

-- Example output snippet:
PARTITION BY RANGE (id)
(PARTITION p0 VALUES LESS THAN (100),
 PARTITION p1 VALUES LESS THAN (200),
 PARTITION p2 VALUES LESS THAN MAXVALUE);

3

Check for any typos, invalid characters, or naming convention violations in the partition names defined here.

4

Compare these defined names with any partition names used in your application code or in explicit `PARTITION (...)` clauses in your queries.

5

If inconsistencies are found, use `ALTER TABLE` statements to rename or recreate partitions as necessary, similar to Solution 3.

-- Example: Renaming a partition
ALTER TABLE your_table RENAME PARTITION old_name TO new_name;
