While inserting the values in a row, we can use the value of self-computed output from any expression, function etc. Here is an example to demonstrate it −
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 | +------+--------------+ | 2 | Gaurav Kumar | +------+--------------+ 1 row in set (0.00 sec)
