MySQL Error 1657: Invalid Partition Value
Description
MySQL Error 1657 indicates an issue during the creation or alteration of a partitioned table. It signifies that you have attempted to define a partition with multiple values where only a single value or expression is expected for that specific partitioning type. This typically happens when specifying partition boundaries for `RANGE` or `LIST` partitions incorrectly.
Error Message
Cannot have more than one value for this type of %s partitioning
Known Causes
3 known causesIncorrect RANGE Partition Syntax
Defining a `RANGE` partition with multiple values within a single `VALUES LESS THAN` clause, where only one value is permitted per boundary definition.
Misconfigured LIST Partition
Specifying multiple comma-separated values for a single `VALUES IN` clause, rather than defining distinct partitions for each value or a list of values belonging to one partition.
Misunderstanding Partitioning Logic
A fundamental misunderstanding of how `RANGE` and `LIST` partitioning types expect their values to be defined, leading to syntax errors where multiple values are provided for a single condition.
