MySQL 1224: Partition not empty.

What is MySQL 1224: Partition not empty.

When encountering the error 1224: Partition not empty in MySQL, follow these steps:

Identify the affected table and partition:

SELECT TABLENAME, PARTITIONNAME FROM informationschema.partitions WHERE TABLESCHEMA = 'yourdatabasename' AND TABLENAME = 'yourtable_name';

Check the data in the specific partition to understand why it's not empty:

SELECT * FROM yourtablename PARTITION(partition_name) LIMIT 10;

If it's safe to remove the data, you can either delete specific rows:

DELETE FROM yourtablename PARTITION(partition_name) WHERE condition; Or, if intending to remove all data from the partition:TRUNCATE TABLE yourtablename PARTITION(partition_name);

After ensuring the partition is empty, retry the operation that caused the error.

If the issue persists, check for foreign key constraints or triggers that might automatically populate the partition:

SELECT TABLENAME, COLUMNNAME, CONSTRAINTNAME, REFERENCEDTABLENAME, REFERENCEDCOLUMNNAME FROM informationschema.KEYCOLUMNUSAGE WHERE TABLESCHEMA = 'yourdatabasename' AND TABLENAME = 'yourtablename';SHOW TRIGGERS FROM yourdatabasename LIKE 'yourtablename';6. Adjust the data manipulation logic or constraints as necessary, ensuring no new data is automatically added to the partition during the operation.
