Substring function example to get particular part of string in SQL Server

Apr 23, 2012
Introduction: 

In this article I will explain what is the substring function and uses of substring function in SQL Server.
Description:
During write query in SQL server I got requirement like split the string and get only some part of it to achieve this functionality I realized it’s better to use SubString function. 

SubString function:

This function is used to get the specified length of string based on specification of start position and required length of string. Generally SubString function will take 3 arguments.

Declaration of SubString function:

SUBSTRING(string, startIndex, length)

In this function

1st Argument specifies the string value

2nd Argument specifies the start position of string from where part of string begins

3rd Argument specifies number of characters to be returned from the specified string

Examples of SubString Function:

EX1:

SELECT SUBSTRING('Suresh Dasari',1,10)

Output: 'Suresh Das'

In above query we declared string as 'Suresh Dasari', starting position of string as 1 and number of characters returned from string as 10

EX2:

SELECT SUBSTRING('Suresh Dasari',3,7)

Output:  'resh Da'

In above query string as 'Suresh Dasari', starting position of string as 3 and number of characters returned from string as 7

Ex3:

Suppose if we want split the column in table then our function declaration will be like this

SELECT SUBSTRING(ColumnName,1,4) as 'SubString' FROM TableName

ex: SELECT SUBSTRING(UserName,1,4) as 'SubString' FROM UserInformation

Above query will return UserName starting from 1 and return 4 characters from string like this

Output:   

SubString
