  • MySQL: Which String Data Types should I avoid?
    MySQL: Which String Data Types should I avoid?
    In MySQL, TEXT and BLOB data types should be avoided. 1) The TEXT type has problems in performance, indexing and storage, and is suitable for using VARCHAR or MEDIUMTEXT/LONGTEXT instead. 2) BLOB type will affect performance and increase complexity. It is recommended to store file paths instead of binary data.
