SQL Right() Function: Complete Guide

 SQL RIGHT() function extracts the given number of characters from the right side of the specified character string. So, if you are searching for a substring of the right part of the main string, you can use the RIGHT() function. It accepts two parameters, the string and no. of characters we are looking for in the string.

SQL Right Function

SQL Right() is a built-in function used to extract a substring starting from the right, followed by the number of characters. The RIGHT() function removes several characters from a string (starting from the right).

Syntax

See the syntax of the SQL Right function.

SELECT RIGHT (string, no_of_characters);

The function accepts two parameters.

Parameters

1. String: The input string from which the substring will be extracted can be a literal string, variable, or column.
2. No_of_characters: The number of characters you wish to extract from the string.

The RIGHT() function returns the value of VARCHAR when the input_string is a non-Unicode character data type and returns an NVARCHAR if the input_string is a Unicode character data type.

Query 1

SELECT RIGHT ('AppDividend.com', 3);

Output

'com'

Here 3 characters were displayed starting from the rightmost part of the string.

Query 2

SELECT RIGHT ('AppDividend.com', 4);

Output

'.com'

Here 4 characters were displayed starting from the rightmost part of the string.

Query 3

SELECT RIGHT ('SQL IS FUN', 4);

Output

' FUN'

Here 3 characters were displayed starting from the rightmost part of the string. Before FUN, there is whitespace, which is also counted as a character.

Query 4

SELECT RIGHT ('SQL IS FUN', 20);

Output

'SQL IS FUN'

Here the number of characters exceeded the length of the string as a whole result string is displayed as an output.

Let’s apply the RIGHT function in a Table.

Table: Employee

Emp_id	First_name	City	State	Phone
101	Rohit	Patna	Bihar	8585145852
201	Shivam	Jalandhar	Punjab	8958458785
301	Karan	Allahabad	Uttar Pradesh	9987845784
401	Suraj	Kolkata	West Bengal	8878989898
501	Akash	Vizag	Andhra Pradesh	9898547500

 

Now, if we want to display the last 7 digits of the Phone, then the following query has to be written:

Query

Select First_name AS Emp_Name, RIGHT (Phone, 7) AS Last_seven_digit 
from Employee;

Output

Emp_Name	Last_seven_digit
Rohit	5145852
Shivam	8458785
Karan	7845784
Suraj	8989898
Akash	8547500

 

So, you can see that the last seven-digit phone number is displayed under the column named Phone.
