CONCAT_WS() 函数如何与 MySQL WHERE 子句一起使用？
当我们将 CONCAT_WS() 函数与 WHERE 子句一起使用时，输出将基于 WHERE 子句中提供的条件。从‘Student’表的例子可以理解如下
例子
mysql> Select CONCAT_WS(' ',Name, Last_name, 'Resident of', Address, 'is studying', Subject)AS 'Student Detail' from student WHERE id = 20; +----------------------------------------------------------------+ | Student Detail | +----------------------------------------------------------------+ | Gaurav Rathore Resident of Jaipur is studying Computers | +----------------------------------------------------------------+ 1 row in set (0.00 sec)登录后复制
