MariaDB Error 1492: Missing Partition Definitions
Description
This error indicates that when creating or altering a partitioned table, MariaDB expects an explicit definition for each declared partition. It occurs when the SQL statement specifies a total number of partitions (e.g., `PARTITIONS 4`) but fails to provide the necessary `VALUES` or `LESS THAN` clauses for all of them.
Error Message
For %s partitions each partition must be defined
Known Causes
3 known causesUndefined Partitions
The `CREATE TABLE` or `ALTER TABLE` statement declares a specific number of partitions (e.g., `PARTITIONS 4`) but does not provide individual `PARTITION p_name VALUES ...` clauses for each one.
Incomplete Partition Definition Syntax
The `PARTITION BY` clause or the subsequent partition definitions contain syntax errors, preventing MariaDB from correctly parsing and recognizing the partition boundaries.
Mismatch in Partition Count
The number of explicitly defined partitions does not match the total number of partitions declared in the `PARTITIONS N` clause, leaving some partitions without a definition.
