MySQL Error 1563: Invalid Partition Constant
Description
This error occurs during table creation or alteration when defining partitions in MySQL. It indicates that a constant value specified within a partition clause, such as `VALUES LESS THAN` or `VALUES IN`, is outside the acceptable range or domain of the partitioning function or the column being partitioned. This prevents the database from correctly assigning rows to partitions.
Error Message
Partition constant is out of partition function domain
Known Causes
4 known causesConstant Value Exceeds Data Type Limit
The literal constant defined in a partition clause (e.g., `VALUES LESS THAN`) is too large or too small for the data type of the column being used for partitioning.
Mismatched Partitioning Expression
The value produced by the partitioning expression (e.g., `YEAR(date_column)`) does not align in type or range with the literal constants used in the partition definitions.
Incorrect RANGE Partition Order
In `RANGE` partitioning, a partition's `VALUES LESS THAN` constant is not strictly greater than the preceding partition's `VALUES LESS THAN` constant, causing an overlap or invalid sequence.
Invalid MAXVALUE Usage
Attempting to define a partition with a value equal to or greater than a previously defined `MAXVALUE` or using `MAXVALUE` incorrectly in a `RANGE` partition scheme.
