Description

Error 1591 indicates that an `INSERT` or `UPDATE` statement attempted to add or modify data in a partitioned table, but the values provided for the partitioning key do not fall within the range or list defined for any existing partition. This means the table's partitioning scheme does not accommodate the data being inserted or updated, leading to a data integrity violation.

Error Message

Table has no partition for some existing values

🔍

Known Causes

3 known causes

⚠️

Partition Key Value Out of Range

The value being inserted or updated for the partitioning key column does not match any of the defined ranges or list values for the table's partitions.

⚠️

Incorrect Partition Definition

The table's partitioning scheme was defined incorrectly, or new data values fall outside the scope of the originally planned partitions.

⚠️

Missing MAXVALUE Partition

For `RANGE` partitioned tables, the absence of a `MAXVALUE` partition can lead to this error when values exceed all explicitly defined ranges.

Solutions

3 solutions available

1. Rebuild Table with Correct Partitioning advanced

This solution involves recreating the table with the correct partitioning scheme, ensuring all data ranges are covered.

1

Identify the table and its partitioning strategy. You can use `SHOW CREATE TABLE your_table_name;` to inspect the current partitioning. Pay close attention to the `PARTITION BY` clause and the defined partitions.

SHOW CREATE TABLE your_table_name;

2

Create a new table with the same schema but with a revised partitioning strategy that covers all expected data values. For example, if you are using RANGE partitioning and a new value falls outside existing ranges, you might need to add a new partition or adjust existing ones.

CREATE TABLE your_table_name_new (
    id INT NOT NULL,
    data VARCHAR(255),
    -- other columns
    PRIMARY KEY (id)
) PARTITION BY RANGE (id) (
    PARTITION p0 VALUES LESS THAN (100),
    PARTITION p1 VALUES LESS THAN (200),
    PARTITION p2 VALUES LESS THAN MAXVALUE -- Example: Catch-all partition
);

3

Insert data from the original table into the new table. Ensure that the `INSERT` statement correctly maps data to partitions if necessary, or that the new partitioning scheme handles it implicitly.

INSERT INTO your_table_name_new (id, data, -- other columns)
SELECT id, data, -- other columns FROM your_table_name;

4

Rename the original table to a backup name and then rename the new table to the original table's name.

RENAME TABLE your_table_name TO your_table_name_old, your_table_name_new TO your_table_name;

5

Verify that the data is accessible and queries run without the error. You can then drop the old table after confirming the migration.

DROP TABLE your_table_name_old;

2. Add a Catch-All Partition easy

This is a quick fix for RANGE partitioning. It adds a partition to capture values that don't fit into existing defined partitions.

1

Identify the partitioning column and type using `SHOW CREATE TABLE your_table_name;`.

SHOW CREATE TABLE your_table_name;

2

If using RANGE partitioning, add a partition with `MAXVALUE` to catch any values that fall outside the defined ranges. This is a common cause of Error 1591.

ALTER TABLE your_table_name
ADD PARTITION (PARTITION p_catchall VALUES LESS THAN MAXVALUE);

3

Verify that queries now work correctly. This will allow existing data with values outside the original ranges to be accessed.

SELECT * FROM your_table_name WHERE partitioning_column = 'some_value_that_caused_error';

3. Review and Adjust Partition Definitions medium

This solution involves carefully examining and modifying existing partition definitions to encompass all data.

1

Obtain the current table definition with partitioning details.

SHOW CREATE TABLE your_table_name;

2

Analyze the `PARTITION BY` clause and the defined partitions. Identify the specific data values that are causing the error. This might require running `SELECT` queries with `WHERE` clauses to find problematic data.

SELECT * FROM your_table_name WHERE partitioning_column > last_defined_partition_value;

3

Modify the existing partitions or add new ones to cover the identified data ranges. For example, if you have `VALUES LESS THAN (100)` and `VALUES LESS THAN (200)`, and your problematic data is 250, you need to add a partition for values above 200.

ALTER TABLE your_table_name
REORGANIZE PARTITION p_old_last_partition INTO (
    PARTITION p_new_last_partition VALUES LESS THAN (250),
    PARTITION p_new_extra_partition VALUES LESS THAN (300)
);

4

Execute the `ALTER TABLE` statement. Be aware that reorganizing partitions can be a resource-intensive operation, especially on large tables.

ALTER TABLE your_table_name
REORGANIZE PARTITION p0 VALUES LESS THAN (100),
PARTITION p1 VALUES LESS THAN (200),
PARTITION p2 VALUES LESS THAN (300);

5

Test your queries to ensure the error is resolved.

SELECT * FROM your_table_name WHERE partitioning_column = 'problematic_value';
