语法如下,以获取表的列名:
select column_name from information_schema.columns where table_schema='yourDatabaseName' and table_name=’yourTableName’;
让我们首先创建一个表-
mysql> create table DemoTable ( EmployeeId int, EmployeeFirstName varchar(20), EmployeeLastName varchar(20), EmployeeAge int, EmployeeCountryName varchar(40), IsMarried tinyint(1), isActive ENUM('ACTIVE','INACTIVE') );
以下是获取表的列名的查询。在这里,我们获取DemoTable的列名-
mysql> select column_name from information_schema.columns where table_schema='web' and table_name='DemoTable';
这将产生以下输出-
+---------------------+ | COLUMN_NAME | +---------------------+ | EmployeeId | | EmployeeFirstName | | EmployeeLastName | | EmployeeAge | | EmployeeCountryName | | IsMarried | | isActive | +---------------------+ 7 rows in set (0.00 sec)
