MySQL Error 1163: Unsupported BLOB/TEXT Column Type
Description
This error occurs when you attempt to create or modify a table to include BLOB or TEXT data types, but the chosen or default storage engine (table type) does not support these large object types. It typically indicates an incompatibility between the data type and the underlying storage mechanism of the table.
Error Message
The used table type doesn't support BLOB/TEXT columns
Known Causes
3 known causesMEMORY Storage Engine Limitation
The MEMORY (HEAP) storage engine is designed for temporary, in-memory tables and explicitly does not support BLOB or TEXT columns due to its architecture.
Unsupported Storage Engine
Using a storage engine that inherently lacks support for BLOB/TEXT data types, such as older or specialized engines not designed for large binary/text data.
Incorrect Table Creation Syntax
An explicit `ENGINE` clause in your `CREATE TABLE` or `ALTER TABLE` statement might specify an incompatible engine for columns defined as BLOB or TEXT.
