This can also mean that a BLOB is very large compared to other types of files.BLOBs can be found everywhere. They are used in databases, spreadsheets, e-mail attachments, and even on websites such as Facebook.

BLOBs are often stored on disk drives, tape backup devices, etc., and are commonly used to store images, video, audio, and other digital files.Binary Large Object (BLOB) is a term coined by IBM in 1982 to describe data objects larger than 4K bytes. A BLOB is a set of related data items stored together in a single database record. The term was later popularized by Microsoft's SQL Server product line.In the context of databases, a BLOB is any type of binary data that exceeds the size limitations of a standard row in a relational table.The main advantage of using BLOBs is that they allow for storing large amounts of data without requiring a separate file system. However, their main disadvantage is that they cannot be easily queried using traditional SQL statements.A typical use case where BLOBs are useful is when storing images, audio files, or video clips. Another example would be if you want to store the text contents of a document.To create a BLOB, use the following syntax: CREATE TABLE my_table( my_column VARCHAR(255) NOT NULL PRIMARY KEY);If you need to insert a BLOB value inside a column, use the LOAD DATA LOCAL INFILE statement. You can specify the name of the BLOB as a parameter. LOAD DATA LOCAL IN FILE 'filename' INTO TABLE my_table;You can also use the COPY command to copy a BLOB value from one table to another.
