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-
