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
