MariaDB Error 1495: Duplicate Values in List Partition
Description
This error indicates that you have specified the same constant value multiple times across different partitions in a `LIST` partitioning scheme. Each value used to define a `LIST` partition must be unique to ensure unambiguous data routing. MariaDB prevents table creation or alteration with such conflicting definitions.
Error Message
Multiple definition of same constant in list partitioning
Known Causes
3 known causesTypographical Error
Accidentally entering the same constant value multiple times due to a typo or copy-pasting existing partition definitions.
Incorrect Partitioning Logic
Attempting to assign the same data value to more than one partition, which is fundamentally disallowed in `LIST` partitioning.
Overlapping Value Ranges
Modifying or adding new partitions without checking for existing values, leading to inadvertent duplication of constants.
