The data types in MySQL can be primarily categorized into the following types:

  1. Numeric data types include integer types (INT, TINYINT, SMALLINT, MEDIUMINT, BIGINT) and floating-point types (FLOAT, DOUBLE, DECIMAL), among others.
  2. Character type: includes fixed-length strings (CHAR) and variable-length strings (VARCHAR), etc.
  3. Date and time types include date (DATE), time (TIME), and date-time (DATETIME, TIMESTAMP) types.
  4. Binary types: including binary large object type (BLOB), binary small object type (VARBINARY), and so on.
  5. Enumeration type: including ENUM type, used to specify one value from a list of values.
  6. Collection type: includes SET type, which is used to specify multiple values within a list of values.

The above are common data types used in MySQL, each having different characteristics such as storage space, value range, and precision. Choose the appropriate data type for storage based on specific needs.
