MySQL根据表名查询表字段，类型，注释等信息的sql语句

SELECT
   t.COLUMN_NAME as name,
   (CASE WHEN t.IS_NULLABLE = 'YES' THEN '1' ELSE '0' END) ,
   (t.ORDINAL_POSITION * 10) ,
   t.COLUMN_COMMENT,
   t.COLUMN_TYPE 
 FROM information_schema.`COLUMNS` t
 WHERE t.TABLE_SCHEMA = (select database()) AND t.TABLE_NAME = upper('sys_user')
