SQL - RIGHT() Function

---

---

The SQL RIGHT() function is used to retrieve the rightmost length characters from the string.

It accepts a string value and a numerical value (say N) as a parameters and returns the specified string up to N characters from right to left. It returns NULL if any argument values are passed as NULL.

Note − If the numerical parameter value is larger than the number of characters in the String, this function will return the actual String.

Syntax

Following is the syntax of the SQL RIGHT() function −

RIGHT(str,len)

Parameters

• str − It is the given string from whose right side a number of characters are to be extracted.

• len − It is the number of characters to extract.

Return value

This function returns the rightmost characters from the actual(current) string.

Example

In the following example,we are using the RIGHT() function to retrieve the rightmost characters with the length of ‘4’ from the the String ‘abcdefghi’.

SELECT RIGHT('abcdefghi', 4);

Output

On executing the above program, it will produce the following output −

+-----------------------+
| RIGHT('abcdefghi', 4) |
+-----------------------+
| fghi                  |
+-----------------------+

Example

Following is another example of the RIGHT() function, and using this function, we are trying to retrieve the rightmost characters with the length of 10 from the actual(current) string ‘Hello how are you’.

SELECT RIGHT('Hello how are you', 10);

Output

Following is the output of the above query −

+--------------------------------+
| RIGHT('Hello how are you', 10) |
+--------------------------------+
| ow are you                     |
+--------------------------------+

Example

If any of the argument passed to this function is NULL, it returns NULL value in the result.

SELECT RIGHT('HelloWorld!', NULL);

Output

The above program produces the following output −

+----------------------------+
| RIGHT('HelloWorld!', NULL) |
+----------------------------+
| NULL                       |
+----------------------------+

Example

You can also pass the numeric value to this function

In the following example, We are passing the numeric value ‘344576000’ as an argument to the RIGHT() function. Then using this function, we trying to retrieve the rightmost characters with the length of 5 from the passed numeric value.

SELECT RIGHT(344576000, 5);

Output

Following is the output of the above statement −

+---------------------+
| RIGHT(344576000, 5) |
+---------------------+
| 76000               |
+---------------------+

Example

You can also pass the column name of a table as an argument to the RIGHT() function to print the desired characters in it. Assume we have created a table in SQL with the name Customersusing the CREATE statement as follows −

CREATE TABLE CUSTOMERS(    
ID INT NOT NULL,    
NAME VARCHAR (20) NOT NULL,    
AGE INT NOT NULL,    
ADDRESS CHAR (25) ,    
SALARY DECIMAL (18, 2));

Now, let's insert four records in to the Customers table using the INSERT statement as shown below −

INSERT INTO CUSTOMERS (ID,NAME,AGE,ADDRESS,SALARY) VALUES (1, 'Ramesh', 32, 'Ahmedabad', 2000.00 ); 
INSERT INTO CUSTOMERS (ID,NAME,AGE,ADDRESS,SALARY) VALUES (2, 'Khilan', 25, 'Delhi', 1500.00 ); 
INSERT INTO CUSTOMERS (ID,NAME,AGE,ADDRESS,SALARY) VALUES (3, 'kaushik', 23, 'Kota', 2000.00 ); 
INSERT INTO CUSTOMERS (ID,NAME,AGE,ADDRESS,SALARY) VALUES (4, 'Chaitali', 25, 'Mumbai', 6500.00 );

The following SQL query prints the last 2 characters from the content of the column Address in the Customers table −

SELECT ID, NAME, ADDRESS, RIGHT(ADDRESS, 2) FROM CUSTOMERS;

Output

Following is the output of the above SQL query −

+----+----------+-----------+-------------------+
| ID | NAME     | ADDRESS   | RIGHT(ADDRESS, 2) |
+----+----------+-----------+-------------------+
|  1 | Ramesh   | Ahmedabad | ad                |
|  2 | Khilan   | Delhi     | hi                |
|  3 | kaushik  | Kota      | ta                |
|  4 | Chaitali | Mumbai    | ai                |
+----+----------+-----------+-------------------+
