MySQL 1224: Partition not empty.

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

  1. Identify the affected table and partition:


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

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


SELECT * FROM yourtablename PARTITION(partition_name) LIMIT 10;

  1. 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);

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



  1. 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.
