How can we combine functions in MySQL?
Combining of functions in MySQL is quite possible by providing a function as the argument of other function. It is also called nesting of functions. To understand it, consider some examples below
mysql> Select UPPER(CONCAT('www.','tutorialspoint','.com'))As Tutorials;
+------------------------+
| Tutorials |
+------------------------+
| WWW.TUTORIALSPOINT.COM |
+------------------------+
1 row in set (0.00 sec)
mysql> Select LOWER(CONCAT('WWW.','TUTORIALSPOINT','.COM'))As Tutorials;
+------------------------+
| Tutorials |
+------------------------+
| www.tutorialspoint.com |
+------------------------+
1 row in set (0.00 sec)The above queries combine UPPER() and LOWER() function with CONCAT() function.
Similarly, we can combine more functions with each other; eve more than two functions can also be combined.
