Find Semi-Colon and split into temp table

Posted on 2008-09-30

Hi, I have a table with two columns, ID, Recipients.

ID      Recipients
1      badboy@microsoft.com
2      rudeboy@microsoft.com;bill.gates@microsoft.co.uk
3      nutter@oracle.com;paul.jones@oracle.co.uk;diamondgeezer@mobiles.com
4      itsupport@spectrum.com

What I want to do is create a another temporary table that will have the same columns but I
want the output to appear like below

ID      Recipients
1      badboy@microsoft.com
2      rudeboy@microsoft.com
2      bill.gates@microsoft.co.uk
3      nutter@oracle.com
3      paul.jones@oracle.co.uk
3      diamondgeezer@mobiles.com
4      itsupport@spectrum.com

So what I want it to do is to go through the recipients column and find if there is
a semi-colon ';' if there is that will mean there is more that one email address so will need
to appear as one row in the temp table.

Thanks

use can make use the below Function which will split based on a delimiter

create FUNCTION [dbo].[GetValuesFromList](
                    @List as Varchar(4000)
                    )

RETURNS @Table Table(Value Varchar(50))

AS    
Begin
     Declare @Sep          Varchar(1)
     Declare @Loc          Int
     Declare @Value     Varchar(100)
         
     
     If LTrim(RTrim(@List)) <> ''
     Begin
     
          Set @Sep = ';'  --- Mention the delimiter
          Set @List = @List + @Sep
         
          While PatIndex('%'+@Sep+'%',@List) <> 0
          Begin
               Set @Loc  =      PatIndex('%'+@Sep+'%',@List)
               Set @Value =     LTrim(Left(@List,@Loc-1))
               Set @List =      Stuff(@List,1,@Loc,'')

               
               
               Insert Into @Table(Value) Values (@Value)
     
          End --While
     End --If
     RETURN
End

go

declare @myArry varchar(1000)
select @myArry ='Oracle;Bill Gates;Windows;SQL 2008;ASP.NET'

select * from dbo.GetValuesFromList(@myArry)

This will do it very fast without any looping, but requires a table of sequential numbers.

A table of sequential numbers is VERY useful in SQL Server not use for this.  If you have a table like that already, replace the table name below in place of vw_nums and the column name containing the number in place of n.
if object_id('[dbo].[fn_DelimitedToTable]') is not null
     drop function [dbo].[fn_DelimitedToTable]
go
create function [dbo].[fn_DelimitedToTable](@DelimitedString nvarchar(max), @Delimiter nvarchar(32))
returns @Values TABLE
     (ident         int not null identity primary key clustered
     ,thePosition   int not null
     ,theValue      nvarchar(max)
     )
as
begin
 
insert into @Values (thePosition,theValue)
		select n, substring(@delimiter + @DelimitedString + @delimiter, n + (datalength(@delimiter)/2), charindex(@delimiter, @delimiter + @DelimitedString + @delimiter, n + len(@delimiter)) - n - len(@delimiter)) as string_value
		from	dbo.vw_Nums
		where
			n <= (datalength(@delimiter + @DelimitedString + @delimiter)/2) - (datalength(@delimiter)/2)
			and substring(@delimiter + @DelimitedString + @delimiter, n, (datalength(@delimiter)/2)) = @delimiter
 
 
 
return
end
