Description

This MySQL error indicates that an operation, such as dropping a partition, was attempted on a partition that does not exist within the specified table. It typically occurs when the partition name provided in the SQL statement is incorrect, or the partition has already been removed from the table structure.

Error Message

Error in list of partitions to %s

Known Causes

3 known causes

⚠️

Incorrect Partition Name

The name of the partition specified in your SQL statement does not exactly match any existing partition for the target table.

⚠️

Partition Already Removed

The partition you are attempting to modify or drop has already been successfully removed by a prior operation.

⚠️

Targeting Wrong Table

The SQL command is being executed against a table that does not contain the specified partition, or is not the intended table.

Solutions

4 solutions available

1. Review Partition Definition Syntax easy

Correct syntax errors in your PARTITION BY clause.

1

Carefully examine the `CREATE TABLE` or `ALTER TABLE` statement that defines or modifies the partitions.

2

Pay close attention to the `PARTITION BY` clause and the subsequent partition definitions. Ensure the partitioning type (RANGE, LIST, HASH, KEY) is correct and that the values or expressions used for partitioning are valid and properly formatted.

Example of a correct LIST partitioning definition:
CREATE TABLE sales (
    id INT NOT NULL,
    amount DECIMAL(10, 2),
    sale_date DATE
) PARTITION BY LIST (YEAR(sale_date))
(
    PARTITION p2023 VALUES IN (2023),
    PARTITION p2024 VALUES IN (2024)
);

3

Common mistakes include incorrect use of `VALUES IN` for LIST partitions, missing commas, or invalid data types for the partitioning key.

2. Verify Partition Values for LIST Partitions medium

Ensure all values for LIST partitions are valid and unique.

1

For `LIST` partitioning, each `VALUES IN` clause must contain a comma-separated list of values that are compatible with the partitioning column's data type.

2

Check that there are no duplicate values across different partitions' `VALUES IN` clauses. Each value must belong to exactly one partition.

Incorrect example (duplicate value):
PARTITION p1 VALUES IN (1, 2),
PARTITION p2 VALUES IN (2, 3);

3

Also, ensure that the values provided are actual literal values or expressions that resolve to literal values at table creation/alteration time. Dynamic expressions that cannot be resolved to a static list might cause this error.

Correct example:
PARTITION p_low VALUES IN (1, 2, 3),
PARTITION p_high VALUES IN (4, 5, 6);

3. Check Partition Expressions for RANGE and LIST Partitions medium

Validate expressions used in RANGE or LIST partitioning.

1

If you are using `RANGE` or `LIST` partitioning with expressions (e.g., `PARTITION BY RANGE (YEAR(date_column))`), ensure these expressions are valid MySQL functions and that their return types are compatible with the partitioning type.

2

For `RANGE` partitioning, the values in `VALUES LESS THAN` must be in ascending order and strictly increasing. For `LIST` partitioning, `VALUES IN` must contain discrete, non-overlapping values.

Example of a valid RANGE partition expression:
CREATE TABLE orders (
    order_id INT,
    order_date DATE
)
PARTITION BY RANGE (YEAR(order_date))
(
    PARTITION p2022 VALUES LESS THAN (2023),
    PARTITION p2023 VALUES LESS THAN (2024),
    PARTITION p2024 VALUES LESS THAN MAXVALUE
);

3

Ensure that the expressions do not evaluate to NULL or an incompatible data type for the partitioning scheme.

4. Recreate Partitions Safely advanced

Rebuild the table with correct partitioning definitions.

1

If the partitioning definition is severely corrupted or difficult to diagnose, consider recreating the table with the correct partitioning scheme.

2

Create a new table with the same structure but with the corrected `PARTITION BY` clause.

CREATE TABLE new_table LIKE original_table;
-- Modify the PARTITION BY clause in the CREATE TABLE statement for new_table
-- to fix the error.

3

Copy the data from the original table to the new table.

INSERT INTO new_table SELECT * FROM original_table;

4

Rename the tables to replace the old one with the new, correctly partitioned table. This is a disruptive operation and should be performed during a maintenance window.

RENAME TABLE original_table TO old_table, new_table TO original_table;

5

Verify that the new table is functioning as expected and that all data has been migrated correctly.
