Using the IN Function with Stored procedure

I have the following ASP Code:

PHP Code:


		
			
if(MLS = "") then MLS = 0

if(MLS2 = "") then MLS2 = 0

if(MLS3 = "") then MLS3 = 0

if(MLS4 = "") then MLS4 = 0

if(MLS5 = "") then MLS5 = 0

if(MLS6 = "") then MLS6 = 0





    '---------------------------

    ' Database I/O

    dim oCon    : set oCon = server.CreateObject("ADODB.Connection")    : oCon.Open(Application("WebConnectionString"))

    dim SQL        : SQL = "EXEC proc_MLS @listingNumber='" & MLS & "','" & MLS2 & "','" & MLS3 & "','" & MLS4 & "','" & MLS5 & "','" & MLS6 & "'"

    

    set rsListings = oCon.execute(SQL)

I have the following Stored Procedure:

PHP Code:


		
			
 CREATE PROCEDURE proc_MLS



    @ListingNumber nvarchar(500)



    

AS





-- return result

select        *

from        tblListings l

left join        tblPersonnel p1    on (l.ListingAgentID = p1.PersonnelID)

left join        tblPersonnel p2    on (l.SecondAgentID = p2.PersonnelID)

left join        tblCities    c    on (l.CityID = c.CityID)

left join        tblCounties co    on (c.CountyID = co.CountyID)

left join        tblStates s    on (co.StateID = s.StateID)

where        ListingNumber IN(@ListingNumber)

and        Active = 1

How do I make the multiple values get parsed correctly into the Stored procedure? I have tried the @ListingNumber= but i keep getting the Parameter Number 2 error and the @Name must come after the form. Any ideas from someone would be helpfull.

I would created a var for each 'MLS' and call the SP with 6 or whatever parameters. So just declare each value in the SP individually and then build it up in the IN() clause.

I can only assume that the command object thinks you are trying to pass multiple parameters when you are in fact only trying to pass one?

HTH.

Thanks

I am actually trying to pass up to 6 mls #'s at once. However i tried building the var's up with the in() but got the parameter 5 and parameter 2 warning from sql that says I cannot pass the @var= after i have already called the first one in the form? I'm guessing maybe create an array or something? Thanks for the help!

What I meant was create your SP to expect 6 parameters and pass the six parameters to it during the call.

PHP Code:


		
			
 CREATE PROCEDURE proc_MLS



    @ListingNumber1 nvarchar(12),

    @ListingNumber2 nvarchar(12),

    @ListingNumber3 nvarchar(12),

    @ListingNumber4 nvarchar(12),

    @ListingNumber5 nvarchar(12),

    @ListingNumber6 nvarchar(12),

    

AS



-- return result

...and call it with somethng like...

PHP Code:


		
			
 SQL = "EXEC proc_MLS('" & MLS & "','" & MLS2 & "','" & MLS3 & "','" & MLS4 & "','" & MLS5 & "','" & MLS6 & "')"

    

    set rsListings = oCon.execute(SQL)

One thing to note that I just thought of is that you are assigning values to the var @listingnumber as you are passing it to the SP. I think this will not work. You need to assign the values to vars then pass them in order as my example.

HTH?

Thanks for the help

Thanks for the help. That should work. Always good to get a new head thinking about it. Sometimes you get too bogged down on the problem that you miss the obvious.
