Answer 1

Here is a function that returns a delimited String as a set of rows

set @string = 'A,B,C,D,E,F'      

select * from tbl_test       
where tbl_test.code in (select r from ftDelimitedAsTable(',',@string )    


  --/*----------------------------------------------------------------
    Create     FUNCTION [dbo].[ftDelimitedAsTable](@dlm char, @string varchar(8000))
    RETURNS 
    --------------------------------------------------------------------------*/
    /*------------------------------------------------------------------------
    declare @dlm  char, @string varchar(1000)
    set @dlm=','; set @string='t1,t2,t3';
    -- tHIS FUNCION RETUNRS IN THE ASCENDING ORDER
    -- 19TH Apr 06
    ------------------------------------------------------------------------*/
    --declare
        @table_var TABLE 
        (id int identity(1,1),
            r varchar(1000) 
         )
    AS
    BEGIN
    -- a.p --
    --Modified  18th Nov. 04

        declare @n int,@i int
        set @n=dbo.fnCountChars(@dlm,@string)+1
        SET @I =1
        while @I <= @N
            begin

                --print '@i='+convert(varchar,@i)+ ' AND INSERTING'
                insert @table_var
                    select dbo.fsDelimitedString(@dlm,@string,@i)
                set @I= @I+1

            end
    --PRINT '*************** ALL DONE'
        if @n =1 insert @TABLE_VAR VALUES(@STRING)
    --select * from @table_var
        delete  from @table_var where r=''
        return
    END
