Table to exchange with partition is temporary: '%s'
MySQL raises error 1733 (ER_PARTITION_EXCHANGE_TEMP_TABLE) with the message "Table to exchange with partition is temporary" when you attempt to run ALTER TABLE ... EXCHANGE PARTITION using a temporary table. Because temporary tables are scoped to the current session, MySQL blocks the swap to prevent orphaned metadata and data corruption.
The operation fails immediately, leaving both the partitioned table and the temporary table unchanged. Production migrations, ETL jobs, and online schema changes that rely on the exchange halt until the problem is corrected.
The primary trigger is that the source table specified in the EXCHANGE PARTITION clause was created with CREATE TEMPORARY TABLE. MySQL forbids exchanging partitions with temporary tables because they disappear automatically when the session ends.
Secondary factors include mismatched table definitions, incorrect partition options, or scripting mistakes where a temporary helper table is generated instead of a permanent one.
Replace the temporary table with a permanent table. Use CREATE TABLE ... LIKE to clone the structure of the partition, fill it with data, and then run ALTER TABLE ... EXCHANGE PARTITION again.
If the table must remain temporary for other logic, copy its data into a new permanent staging table just before the exchange, then drop the staging table afterward.
In deployment pipelines, migration tools often stage data in temporary tables for speed. Convert these to regular tables or add a cleanup step that drops them later.
In analytics workflows executed through Galaxy, ensure the AI copilot generates CREATE TABLE statements without the TEMPORARY keyword when planning partition exchanges.
Standardize migration scripts to use permanent staging tables. Validate table type and structure before running EXCHANGE PARTITION by querying INFORMATION_SCHEMA.TABLES.
Automate pre-checks in CI/CD using SELECT TABLE_TYPE to confirm no temporary tables are referenced in DDL statements.
Error 1732 (ER_PARTITION_EXCHANGE_DIFFERENT_OPTION) occurs when the source table lacks identical table options. Align ENGINE, ROW_FORMAT, and INDEX definitions to resolve.
Error 1517 (ER_DROP_PARTITION_NON_EXISTENT) appears when dropping a non-existent partition. Verify partition names with SHOW CREATE TABLE before executing DDL.
The referenced table was created with CREATE TEMPORARY TABLE, so MySQL blocks the exchange.
Automated tools mistakenly prepend TEMPORARY to staging tables used in deployment or ETL flows.
A developer manually created a temporary table for testing and then reused it in production DDL.
Occurs when the table options of the source table differ from the partitioned table. Align ENGINE, ROW_FORMAT, and COLLATION to fix.
Raised when attempting to drop a partition that does not exist. Verify partition names with SHOW CREATE TABLE or INFORMATION_SCHEMA.PARTITIONS.
Indicates misuse of subpartition definitions. Ensure correct partitioning syntax and supported storage engine.
No. MySQL explicitly disallows TEMPORARY tables in EXCHANGE PARTITION operations because the table could vanish at session end, risking metadata corruption.
WITHOUT VALIDATION only skips foreign key and constraint checks. It does not bypass the temporary-table restriction.
Renaming does not change table type. You must create a new permanent table or recreate the original without the TEMPORARY keyword.
Galaxy’s AI copilot and schema-aware linting highlight TEMPORARY table usage in partition exchanges, guiding you to convert them to permanent tables before execution.
