MySQL 1252: Partition does not exist.

  1. Verify the existence of the partition:


SELECT PARTITIONNAME FROM INFORMATIONSCHEMA.PARTITIONS WHERE TABLESCHEMA = 'yourdatabasename' AND TABLENAME = 'yourtablename';

  1. Check the table's partitioning scheme:


SHOW CREATE TABLE yourtablename\G

  1. If the partition supposed to exist, try to reorganize partitions if applicable or adjust your query to target existing partitions. If attempting reorganization, ensure you have a backup:


ALTER TABLE yourtablename REORGANIZE PARTITION existingpartition INTO (PARTITION newpartition VALUES LESS THAN (...));

  1. If the partition is missing and needs to be created:


ALTER TABLE yourtablename ADD PARTITION (PARTITION partition_name VALUES LESS THAN (...));

  1. Verify that the partition was added successfully:


SELECT PARTITIONNAME FROM INFORMATIONSCHEMA.PARTITIONS WHERE TABLESCHEMA = 'yourdatabasename' AND TABLENAME = 'yourtablename';
