MariaDB Error 1493: Partition Range Order
Description
This error occurs during the creation or alteration of a table with RANGE partitioning. It indicates that the 'VALUES LESS THAN' specifications for consecutive partitions are not in strictly ascending order. This violates the fundamental requirement for range partitioning to ensure distinct, non-overlapping ranges.
Error Message
VALUES LESS THAN value must be strictly increasing for each partition
Known Causes
3 known causesMisordered Range Values
The 'VALUES LESS THAN' clauses are defined in a descending or non-strictly increasing sequence, rather than ascending.
Duplicate Partition Bounds
Two or more 'VALUES LESS THAN' clauses specify the same upper bound, preventing a strictly increasing sequence.
Overlapping Partition Ranges
A subsequent partition's 'VALUES LESS THAN' value is less than or equal to a preceding partition's value, creating an overlap.
