如何将 CONCAT_WS() 函数与 MySQL WHERE 子句配合使用?
当将 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。可以从以下“学生”表的示例中理解这一点
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 |
+----------------------------------------------------------------+
