A BLOB is a binary large object that can hold a variable amount of data. There are four types of BLOB
- TINYBLOB
- BLOB
- MEDIUMBLOB and
- LONGBLOB
They all differ only in the maximum length of the values they can hold.
A TEXT is a case-insensitive BLOB. There are four TEXT types
- TINYTEXT
- TEXT
- MEDIUMTEXT and
- LONGTEXT
They all correspond to the four BLOB types and have the same maximum length and storage requirements.
The only difference between BLOB and TEXT types is that sorting and comparison is performed in case-sensitive for BLOB values and case-insensitive for TEXT values.
