参考===MySQL 建表语句 create table 中的列定义：

column_definition:

    data_type [NOT NULL | NULL] [DEFAULT default_value]

      [AUTO_INCREMENT] [UNIQUE [KEY]] [[PRIMARY] KEY]

      [COMMENT 'string']

      [COLUMN_FORMAT {FIXED|DYNAMIC|DEFAULT}]

      [reference_definition]

  | data_type [GENERATED ALWAYS] AS (expression)

      [VIRTUAL | STORED] [NOT NULL | NULL]

      [UNIQUE [KEY]] [[PRIMARY] KEY]

      [COMMENT 'string']
