RIGHT() Example 1 : NULL Arguments
It will return NULL, if any of the argument is NULL. Lets see the below example when length, second argument is NULL.
mysql> SELECT RIGHT('tutorialmines',NULL); +-----------------------------+ | RIGHT('tutorialmines',NULL) | +-----------------------------+ | NULL | +-----------------------------+ 1 row in set (0.03 sec)
Lets see the below example, when string, first argument is NULL.
mysql> SELECT RIGHT(NULL,5); +---------------+ | RIGHT(NULL,5) | +---------------+ | NULL | +---------------+ 1 row in set (0.05 sec)
RIGHT() Example 2 : Basic Usage
Lets see the below example. I will select 8 characters from the right of string.
mysql> SELECT RIGHT('tutorialmines',8); +--------------------------+ | RIGHT('tutorialmines',8) | +--------------------------+ | ialmines | +--------------------------+ 1 row in set (0.00 sec)
RIGHT() Example 3 :
If length parameter has more than the number of characters in string.
Lets see the below example. Full string is returned in it.
mysql> SELECT RIGHT('tutorialmines',28); +---------------------------+ | RIGHT('tutorialmines',28) | +---------------------------+ | tutorialmines | +---------------------------+ 1 row in set (0.00 sec))
