Unlike the numeric data types, you do not have to set a length next to the TEXT data type in the table column. The storage size of the TEXT data type varies from 1 byte to 4 GB. The MySQL TEXT data type is used to store long-text strings to display information about the table object, such as product descriptions, blog comments, etc. The MySQL string data types are divided into: Strings can consist of letters, numbers, or binary media files such as images, photos, or audio files.

When specifying data types, you can set a field size. A data type also indicates a data range to be stored in each column of the table. When creating a table, you need to specify a table name and a data type that not only defines what data can be stored in the table column but also what influence it may have on database performance. Selecting an appropriate data type can be very important. MySQL Numeric Data Types (Number Formats).Also, we’ll provide examples of their usage and see how to change a data type for the table column using dbForge Studio for MySQL.
