我们如何使用 MySQL 自计算的任何表达式、函数等的输出来在行中插入值？

mysql> Insert into employee(id, emp_name)Select 1+1, Concat_ws(' ','Gaurav', 'Kumar');
Query OK, 1 row affected (0.04 sec)
Records: 1 Duplicates: 0 Warnings: 0

mysql> Select * from employee;
+------+--------------+
| id   | emp_name     |
+------+--------------+
| 两    | Gaurav Kumar |
+------+--------------+
1 row in set (0.00 sec)
