<p>The table is partitioned, but no partition matches the value supplied in the INSERT, UPDATE, or LOAD operation.</p>
<p>MySQL Error 1526: ER_NO_PARTITION_FOR_GIVEN_VALUE occurs when a partitioned table receives a row whose partition key does not map to any defined partition. Add or adjust partitions, or correct the key value, to resolve the error quickly.</p>
Table has no partition for value %s
The error arises at runtime when MySQL attempts to write a row into a partitioned table but cannot find a matching partition for the supplied partition key value.
MySQL aborts the statement and returns SQLSTATE HY000 with the message Table has no partition for value %s, protecting data integrity.
The error typically shows up during INSERT, LOAD DATA, REPLACE, or UPDATE statements that target a partitioned table.
It can also occur while executing ALTER TABLE EXCHANGE PARTITION or importing data through replication if partitions are misaligned between master and replica.
Ignoring the error blocks data ingestion, halts ETL pipelines, and may cause replication lag or failure.
Timely resolution ensures continuous data flow and maintains consistency across sharded or partitioned workloads.
A RANGE or LIST partitioning scheme omits the supplied key, leaving no partition to accept the row.
The SQL statement provides a NULL or out-of-range value for the partition column.
An administrator removed a partition without adjusting incoming data logic, creating a gap.
Replication targets have differing partition definitions from the source, leading to errors during replay.
Fails when the partition function evaluates to NULL or invalid output.
Raised when there is a mismatch between partition and subpartition definitions.
Occurs during UPDATE when the new values no longer match the current partition.
No. Only tables defined with PARTITION BY clauses can raise Error 1526.
MySQL does not provide a safe switch to bypass partition checks, as it would risk corrupting data placement.
Often yes, but it may store unbounded data. Periodically split MAXVALUE into smaller ranges to maintain manageability.
Galaxy's context-aware AI warns you when an INSERT targets an uncovered partition range and suggests ALTER TABLE statements to extend partitions before execution.
