MySQL data types

MySQL supports the following data types:

Text types: VARCHAR, CHAR, TEXT, BLOB, CLOB

Numeric types: INT, TINYINT, SMALLINT, MEDIUMINT, BIGINT, FLOAT, DOUBLE, DECIMAL

Date and time types: DATE, TIME, DATETIME, TIMESTAMP

Special types: ENUM, SET, JSON, BIT

Choosing the data type for each field in a table is an important decision, as it affects the efficiency of the database. For example, if a field contains only short text values, then the VARCHAR(255) type can be used. If a field contains long text values, then the TEXT or BLOB type can be used. If a field contains numbers, then the INT or SMALLINT type can be used for small numbers or the BIGINT type for large numbers.
