Differences Between BLOB and TEXT Datatypes in MySQL
When dealing with data storage in MySQL, you may encounter two specific data types: BLOB and TEXT. To understand their distinctions and appropriate usage, let's delve into their characteristics:
BLOB (Binary Large OBject)
BLOB is a binary data type used for storing large amounts of raw binary data, such as images, files, or videos. It is designed for scenarios where data needs to be preserved in its original binary format.
TEXT

When to Use BLOB and TEXT
The selection between BLOB and TEXT depends on the type of data you need to store:
Understanding MEDIUMBLOB and MEDIUMTEXT
The MEDIUMBLOB and MEDIUMTEXT datatypes have a length limit of 16MB. However, they have an additional L byte denoting the actual length of the stored data.
Conclusion
BLOB and TEXT provide distinct functionality in MySQL for handling binary and character data, respectively. By understanding their differences, you can effectively manage your database storage and optimize its performance.
