MariaDB Error 1502: BLOB Field in Partition Function
Description
This error occurs when you attempt to use a BLOB (Binary Large Object) data type column as part of a table's partitioning key or within a partitioning function expression. MariaDB's partitioning mechanism requires columns used for partitioning to be of discrete, comparable types, which BLOB fields are not.
Error Message
A BLOB field is not allowed in partition function
Known Causes
3 known causesDirect BLOB Partitioning
You are attempting to directly specify a BLOB column as the partitioning key in a CREATE TABLE or ALTER TABLE statement with the PARTITION BY clause.
BLOB in Partition Function Expression
An expression within your PARTITION BY clause includes or references a BLOB column, making the entire function incompatible with partitioning rules.
Inappropriate Data Type Choice
A column was defined as BLOB when a more suitable, partition-compatible data type (like VARCHAR, VARBINARY, or a numeric type) should have been used for the intended partitioning scheme.
