顯示一個表的結構的MySQL查詢

要顯示一個表的結構，以下為語句語法 −

show create table yourTableName;

我們先建立一個表 −

mysql> create table DemoTable
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> EmployeeFirstName varchar(100),
   -> EmployeeLastName varchar(100),
   -> EmployeeAge int,
   -> isMarried tinyint(1),
   -> EmployeeAddress varchar(100),
   -> EmployeeCountryName varchar(100)
   -> );
Query OK, 0 rows affected (0.62 sec)

以下為顯示結構的查詢 −

mysql> show create table DemoTable;

輸出

這將生成以下輸出 −
