In this article, I am going to explain how to split comma-separated strings in an SQL server and also show you how to create a function in an SQL server as well as how you can get comma-separated strings in the form of a SQL table.

While you working with a data-driven application sometimes you have string data as input and you need that all input data in tabular format and you need to split your input string data by any separator like comma(','), ('/'), single quotes, double quotes and etc.

Today I got the same requirement I have a comma-separated string with the names of all the students and I need an SQL table for all these students to display those records within a grid. So I have written a SQL function "Split" this function splits input string with a separator passed within the function as a parameter and through this article that function I wanna share with you.


1) Create Function in SQL Server.
2) Split Input String with Separator that passed within the function as input.
3) Return SQL Table with all these data available within the input string.


Before starting our actual implementation I just wanna show you a basic syntax to create a function in the SQL server

Syntax to Create Function in SQL Server

CREATE FUNCTION [dbo].[Name_Of_Function]
-- required parameters
 -- Your logical sql statements
Now I will show you how o write a SQL function to archive our requirement and spit string by comma and return an SQL table.
@InputString NVARCHAR(MAX), 
@Separator NVARCHAR(10)
ItemValue NVARCHAR(max)
    DECLARE @xml XML;
    SELECT    @xml = CAST('<input>' + REPLACE(@InputString, @Separator, '</input><input>') + '</input>' AS XML);
    INSERT INTO @tbl(ItemValue)
    SELECT  Temp.split.value('.', 'NVARCHAR(max)') AS ItemValue
    FROM    @xml.nodes('/input') Temp(split)
Now we will execute this function as a table with the select statement and get the result as an SQL table with data as per the input string.
SELECT ItemValue FROM Split('Nikunj Satasiya,Hiren Dobariya,Vivek Ghadiya,Pratik Pansuriya',',')


If you analyzed the above-created SQL function to split input string with a comma then I return table variable @tbl with column ItemValue and then after I have declared variable @xml then I have created XML node as <input></input> with input data and stored in declared variable @xml. Now, I simply insert a value within the declared table variable from created XML nodes and return that table variable as an SQL table.

And finally I wort a query for selecting data from the table and executing that function and this function is returned to a SQL table as given in the output window.
