Q. What is BLOB and TEXT in MySQL......? β˜› BLOB is an acronym stands for a large binary object. It is used to hold a variable amount of data. There are four types of the BLOB. ✨ TINYBLOB ✨ BLOB ✨ MEDIUMBLOB ✨ LONGBLOB The differences among all these are the maximum length of values they can hold.
