<p>The table you want to swap into a partition is itself partitioned, so MySQL blocks ALTER TABLE ... EXCHANGE PARTITION.</p>
<p>MySQL Error 1732 ER_PARTITION_EXCHANGE_PART_TABLE appears when you run ALTER TABLE ... EXCHANGE PARTITION and the target table is partitioned. Convert the child table to a non-partitioned table or use REMOVE PARTITIONING, then re-issue the exchange command.</p>
Table to exchange with partition is partitioned: '%s'
MySQL throws error 1732 with the message Table to exchange with partition is partitioned when an ALTER TABLE ... EXCHANGE PARTITION statement tries to swap a partition with a standalone table that is already partitioned.
The operation requires the standalone table to have identical structure and indexes but must not contain any partitioning metadata. If MySQL detects partition definitions on that table, it halts the command and raises this error.
During EXCHANGE PARTITION, MySQL simply switches the data dictionary pointers between the partition and the standalone table. Mixing two partitioned entities would create nested partitioning, an unsupported state that could corrupt metadata. Therefore, the server rejects the request.
Developers often hit 1732 while reorganizing large tables for maintenance or archiving, or when using staging tables in a Galaxy workspace before promoting data into production partitions.
The exchange fails, leaving both the partition and the staging table unchanged. Queries continue to read old data, which can break ETL pipelines and delay deployments.
The staging table inherits partitioning from a template or was created with a LIKE clause that copied partition metadata.
Using CREATE TABLE ... SELECT from a partitioned source often carries over partition syntax.
The target table uses RANGE partitioning while the parent uses LIST, causing MySQL to treat structures as incompatible.
Raised when the table to exchange is a temporary table.
Occurs when a column used in a partition function is not part of every unique key.
Triggered by mismatched columns in a LIST or RANGE COLUMNS partition.
No. MySQL prohibits exchanging partitioned tables, even if layouts match, to avoid nested partition hierarchies.
No. It converts the table to a single unpartitioned tablespace without touching row data.
WITHOUT VALIDATION skips row-by-row checks. Use it only when you are sure keys fall within the partition range.
