MySQL查询显示表结构

要显示表的结构，以下是语法-

show create table yourTableName;

让我们首先创建一个表-

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)
   -> );

这是显示结构的查询-

show create table DemoTable;

输出结果

这将产生以下输出-
