如何将CONCAT_WS()函数与MySQL WHERE子句一起使用？
当我们在WHERE子句中使用CONCAT_WS()函数时，输出将基于WHERE子句中提供的条件。从“学生”表的示例可以理解如下
示例
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 |
+----------------------------------------------------------------+
