In the computer world, however, blobs are a bit easier to define. The term "blob" actually stands for "Binary Large Object" and is used for storing information in databases. A blob is a data type that can store binary data.

.

Furthermore, what Is A BLOB type?

A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. The data type became practical when disk space became cheap.

Beside above, when would you use a BLOB data type? BLOB is used for storing binary data while Text is used to store large string. BLOB values are treated as binary strings (byte strings). They have no character set, and sorting and comparison are based on the numeric values of the bytes in column values.

Secondly, what is SQL BLOB data type?

A BLOB, or Binary Large Object, is an SQL object data type, meaning it is a reference or pointer to an object. Typically a BLOB is a file, image, video, or other large object. In database systems, such as Oracle and SQL Server, a BLOB can hold as much as 4 gigabytes. MySQL supports four BLOB types: TINYBLOB - 256 bytes.

What Is A BLOB storage?

What is data type in SQL?
