在将值插入一行时,我们可以使用任何表达式,函数等的自计算输出值。下面是一个示例来演示它-
mysql> Insert into employee(id, emp_name)Select 1+1, Concat_ws(' ','Gaurav', 'Kumar'); Records: 1 Duplicates: 0 Warnings: 0 mysql> Select * from employee; +------+--------------+ | id | emp_name | +------+--------------+ | 2 | Gaurav Kumar | +------+--------------+ 1 row in set (0.00 sec)
