When should a BLOB be used?

It is used for storing binary data (i.e. data which can contain non-printable characters as well as arbitrary bit patterns). Typical examples of such data types include images, audio files, compressed files and spreadsheet data.

How BLOB is used in database?

The only difference being usage of BLOB data type instead of any other data type. We can simply use the keyword BLOB for using binary large object data type in MySQL and ORACLE databases. However, other databases such as PostgreSQL and SQL SERVER call binary large objects data types as BYTEA, binary instead.
