MariaDB Error 1657: Invalid Partitioning Value Count
Description
Error 1657 indicates an issue with a table's partitioning definition, specifically when a partition type expects a single value or expression but receives multiple. This typically occurs during `CREATE TABLE` or `ALTER TABLE` statements when defining `RANGE`, `LIST`, `HASH`, or `KEY` partitions with incorrect syntax for the partitioning expression or values clause.
Error Message
Cannot have more than one value for this type of %s partitioning
Known Causes
3 known causesIncorrect RANGE or LIST Syntax
Providing multiple values in a `VALUES IN (...)` clause for `LIST` partitioning or multiple `VALUES LESS THAN (...)` for `RANGE` when the partition key is a single column.
Multiple Columns in Partitioning Expression
Specifying multiple columns directly in the `PARTITION BY` clause for partition types that expect a single expression, such as `PARTITION BY RANGE (col1, col2)`.
Misunderstanding Partitioning Type Requirements
Applying a partitioning definition that implicitly generates multiple values for a partition type that strictly requires a single, scalar value or expression.
