How to Split large comma separated string into table in Sql Server

Introduction:  In this article I am going to explain how to convert a comma separated string into table rows in Sql server.

In previous articles i explained How to Convert column values to comma separated list in sql server and Multiple queries to get all dates between two dates and create database script and Create database from that script and Examples to use CASE Expression in SELECT statement in SQL Server

In the Query window of the Sql Server write the following command.

      DECLARE @Splitted_string NVARCHAR(4000)

      DECLARE @Pos INT

      DECLARE @NextPos INT

      DECLARE @Str NVARCHAR(4000)

      DECLARE @Delimiter NVARCHAR(1)

      DECLARE @Temp TABLE(Result NVARCHAR(100))

      SET @Str ='split,string,separated,by,comma,example,in,sql,server'

      SET @Delimiter = ','

      SET @Str = @Str + @Delimiter

      SET @Pos = CHARINDEX(@Delimiter,@Str)

      WHILE (@pos <> 0)

      BEGIN

                          SET @Splitted_string = SUBSTRING(@Str,1,@Pos - 1)              

                          SET @Str = SUBSTRING(@Str,@pos+1,LEN(@Str))

                          SET @pos = CHARINDEX(@Delimiter,@Str)      

                          INSERT INTO @Temp VALUES(@Splitted_string)

      END

     

      SELECT * FROM @Temp

Result will be as:

Result
