Description

This error occurs when an attempt is made to insert or update a row with a value for the partitioning key that does not fall within any of the table's defined partitions. It indicates a mismatch between the data being processed and the table's partitioning scheme, preventing the operation from completing.

Error Message

Table has no partition for value %s

Known Causes

3 known causes

⚠️

Value Outside Defined Partition Ranges

The data being inserted or updated contains a value for the partitioning column that does not match any of the existing partition definitions (e.g., it's outside all specified ranges or not in any list).

⚠️

Missing Catch-All Partition

The table's partitioning scheme lacks a `MAXVALUE` partition (for range partitioning) or a `DEFAULT` partition (for list partitioning) to handle unspecified or unforeseen values.

⚠️

Incorrect Partitioning Key Data

The value provided for the partitioning key column is unexpected or invalid according to the table's partitioning logic, leading to no available partition.

Solutions

4 solutions available

1. Insert into the Correct Partition easy

Ensure your INSERT statements target the specific partition where the data belongs.

1

Identify the partitioning scheme of your table. You can do this by running `SHOW CREATE TABLE your_table_name;`.

SHOW CREATE TABLE your_table_name;

2

Examine the `PARTITION BY` clause to understand how data is distributed. For example, if it's `PARTITION BY RANGE (column_name)`, you'll need to know the range boundaries.

SHOW CREATE TABLE your_table_name;

3

When inserting data, explicitly specify the partition if your partitioning strategy allows for it (e.g., using `PARTITION (partition_name)`). More commonly, ensure the value you are inserting falls within the defined range or set for an existing partition.

INSERT INTO your_table_name PARTITION (partition_name) (column1, column2) VALUES (value1, value2); -- If applicable and known
-- OR simply ensure the value falls into a defined partition:
INSERT INTO your_table_name (column1, column2) VALUES (value_that_fits_partition, value2);

2. Add a New Partition medium

Create a new partition to accommodate the value that is currently not falling into any existing partition.

1

Identify the partitioning scheme and the value causing the error. You can use `SHOW CREATE TABLE your_table_name;` to see the current partitioning.

SHOW CREATE TABLE your_table_name;

2

Determine the appropriate range or list of values for the new partition based on your partitioning strategy and the problematic value.

SELECT MAX(your_partition_column) FROM your_table_name; -- To understand current data range
-- If it's RANGE partitioning, you might need to define a new range like:
-- NEW_MAX_VALUE

3

Use the `ALTER TABLE ... ADD PARTITION` statement to create the new partition. The exact syntax depends on your partitioning type (RANGE, LIST, HASH, KEY).

-- For RANGE partitioning:
ALTER TABLE your_table_name ADD PARTITION (PARTITION new_partition_name VALUES LESS THAN (new_upper_bound));

-- For LIST partitioning:
-- ALTER TABLE your_table_name ADD PARTITION (PARTITION new_partition_name VALUES IN (value1, value2));

4

After adding the partition, attempt the insert operation again. The value should now have a partition to go into.

INSERT INTO your_table_name (your_partition_column, other_column) VALUES (value_that_now_fits, 'some_data');

3. Reorganize Partitions to Include the Value advanced

Modify existing partitions to encompass the value that is causing the error.

1

Examine your table's partitioning using `SHOW CREATE TABLE your_table_name;`.

SHOW CREATE TABLE your_table_name;

2

Identify the partition that the problematic value *should* belong to, or determine if a new partition needs to be created by adjusting the boundaries of existing ones.

-- Example: If you have partitions for < 100 and < 200, and your value is 150, it might fit in the second partition.
-- If your value is 250 and the last partition is < 200, you need to extend the last partition's range.

3

Use `ALTER TABLE ... REORGANIZE PARTITION` to modify the boundaries of existing partitions. This is a more complex operation and might involve creating a new partition and dropping/merging an old one.

-- Example: Reorganizing a partition to include a higher range (assuming RANGE partitioning)
ALTER TABLE your_table_name REORGANIZE PARTITION old_partition_name INTO (PARTITION new_partition_name VALUES LESS THAN (new_upper_bound));

-- Note: This can be a complex operation. It might be safer to add a new partition as per Solution 2.

4

After reorganizing, the problematic value should now have a valid partition. Retry your insert.

INSERT INTO your_table_name (your_partition_column, other_column) VALUES (value_that_now_fits, 'some_data');

4. Drop Partitioning (Temporary or Permanent) medium

Remove partitioning from the table to allow all inserts, then re-evaluate partitioning strategy.

1

Back up your data before proceeding, as removing partitioning can be a significant change.

mysqldump -u your_user -p your_database your_table_name > your_table_name_backup.sql

2

Disable partitioning for the table. This effectively makes it a non-partitioned table, allowing all inserts.

ALTER TABLE your_table_name REMOVE PARTITIONING;

3

Attempt your insert operation. It should now succeed.

INSERT INTO your_table_name (your_partition_column, other_column) VALUES (value_that_was_failing, 'some_data');

4

Once you have resolved the immediate issue and analyzed your data distribution, you can re-partition the table with a more suitable scheme or consider if partitioning is still necessary.

-- To re-partition, you'll need to define a new partitioning strategy and use ALTER TABLE ... PARTITION BY ...
