What is TEXT data type in MySQL?
TEXT data objects are useful for storing long-form text strings in a MySQL database. Followings are some point about TEXT data type −
- TEXT is the family of column type intended as high-capacity character storage.
- The actual TEXT column type is of four types-TINYTEXT, TEXT, MEDIUMTEXT and LONGTEXT.
- The four TEXT types are very similar to each other; the only difference is the maximum amount of data each can store.
- The smallest TEXT type, TINYTEXT shares the same character length as VARCHAR.
- TEXT values are treated as character strings.
- TEXT has character set other than binary character set and collation.
- The comparisons and sorting are based on the collation of its character set.
- Truncation of excess trailing spaces from values to be inserted into TEXT columns always generates a warning, regardless of the SQL mode.
- A TEXT family column is just like a VARCHAR.
- TEXT column cannot have DEFAULT value.
