Default SQL Stored Procedure...

Hi,

I have a stored procedure like this...

CREATE PROCEDURE Test
(@UList [varchar](50))
 AS
select * from [User] where UserID in (@UList)
GO

The statement that's required for execution would be,
exec Test '10,11'

But, this gives me an error.
How do I do this part of passing multiple UserIDs for this table?

regds,
Babloo

Hi there,

Unfortunately, you can't do that directly. The IN clause expects a comma separated list of values, not a string that holds a list of comma separated values.

There are a couple of ways around this. One solution is to build the SQL statement dynamically, and then use EXEC to execute it against the database. Another solution is to parse the string, insert the values in a temp table and then join that table with your original table.

Take a look here for a more detailed discussion on the options you have available:

http://vyaskn.tripod.com/passing_arr...procedures.htm

Another solution that has been posted to this list (the temp table solution):
Code:
CREATE FUNCTION Inlist (@list varchar(8000))
 RETURNS @tbl TABLE (val int not null)  AS  
 BEGIN 
        Declare @index int,
                @pos int,
                @str varchar(8000),
                @num int
        Set @pos = 1
        Set @index = 1
        While @index > 0
        Begin
                set @index = charindex(',', @list, @pos)
                if @index > 0
                        Set @str = substring(@list, @pos, @index - @pos)
                Else
                        Set @str = substring(@list, @pos, Len(@list))
                     Set @str = ltrim(rtrim(@str))
                Set @num = cast(@str as integer)
                Insert @tbl (val) values (@num)
                Set @pos = @index + 1
        End
        Return
 End
 --------------------------------
 Used in a select statement as followed:
"SELECT * FROM MyTable WHERE ID NOT IN (select val from inlist('1,2,3'))"
HtH,
