MariaDB Error 1564: Invalid Partition Function
Description
This error indicates that the function used in a table's `PARTITION BY` clause is not permitted by MariaDB. It typically occurs during `CREATE TABLE` or `ALTER TABLE` statements when defining or modifying a table's partitioning scheme.
Error Message
This partition function is not allowed
Known Causes
4 known causesUnsupported Partition Function
Attempting to use a function in a `PARTITION BY` clause that is not explicitly supported by MariaDB for partitioning (e.g., non-deterministic functions, or functions not listed in the official documentation).
Non-Integer Function Return Type
The chosen function does not evaluate to an integer type, which is a fundamental requirement for partition key expressions in MariaDB.
Function Mismatch with Partition Type
The selected function is syntactically correct but semantically inappropriate or incompatible for the specified partitioning type (e.g., `RANGE`, `LIST`, `HASH`, `KEY`).
Use of User-Defined Function (UDF)
MariaDB generally restricts the use of custom or user-defined functions within table partitioning expressions due to complexity and potential issues.
