Recordset syntax

I have two tables customers and addresses. I want to get all addresses belonging to a given customer using stored procedure, a wrapper function and finaly use this function in my asp file.

here is the customer table.
-------------------------------------------------------------
CREATE PROCEDURE spAddress(@companyName varchar(50) )
as
Select *
From
Customers Inner Join addresses on
Customers.RecNumber = addresses.RecNumber
Where
Customers.CompanyName=@CompanyName
-------------------------------------------------------------

------------------------------------------------------------------------------------
here is the wrapper function

function wrpGetAddress(Conn, CompanyName)
Dim cmd
Set cmd = Server.CreateObject("ADODB.Command")

With cmd
.ActiveConnection = objConn
.CommandText = "usr.spAddress"
.CommandType = adCmdStoredProc
End With

Set param = cmd.CreateParameter("companyName", advarchar, adParamInput, 50, CompanyName)
cmd.Parameters.Append param

set wrpGetAddress = cmd.Execute
end function

------------------------------------------------------------------------------------

Now I use the above function in my asp page.

Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open Database, User, Password

CompanyName = "IBM"

Set Rst = Server.CreateObject("ADODB.Recordset")
Rst = wrpGetAddress(Conn, CompanyName)

Rst.moveLast

--------------------------------------------------------------------------------------

Error is

Relationship

Microsoft VBScript runtime error '800a01b6'

Object doesn't support this property or method: 'Rst.MoveLast'

/temp/test.asp, line 50

I want to use the stored procedure and the wrapper function. But I need to tell that the returned recordset must be dynamic. I don't know the syntax

aioudine

Open RecordSet with Client Side cursor
something like that
-----------------
sConnection = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=zulu;Data Source=DATACENTER;Connect Timeout=2000"

Set oConn = Server.CreateObject("ADODB.Connection")
oConn.Open sConnection

Set oCmd = Server.CreateObject("ADODB.Command")
Set oCmd.ActiveConnection = oConn
oCmd.CommandText = cProcedureName
oCmd.CommandType = adCmdStoredProc
oCmd.CommandTimeout = 120

Set oRs= Server.CreateObject("ADODB.Recordset")
oRs.ActiveConnection = oConn
oRs.CursorLocation = adUseClient
oCmd.Parameters.Append

oCmd.CreateParameter( "@Id", adInteger, adParamInput, ,iId )
oRs.Open oCmd

aioudine

other wise you may use
RsCustomerList.CursorType = adOpenKeyset
RsCustomerList.LockType = adLockOptimistic

I have been trying to implement your suggestions but it seems I am having hard time making it work.
All I want is to make the wrapper function return a dynamic recordset and I assign it a record set I declare in the main asp file.
If that can't be done please let me know.
I would appreciate if you can modify my wrapper function and the main asp file separately and show me the result.

Preferably, you may cut and past my entire original question and modify the wrapper function which lives different file than the calling main asp file.

Than you

yassin,
Instead of passing objects as argument parameters which is an inefficient method you could alter your code.
There are many methods you can accomplish what you have asked. But before I elaborate, your error for "rs.MoveLast property not supported" it could be either that your procedure or your cmd.Execute returned an empty recordset or the driver you are using for the connection genuinely does not support the property.
'******************************
'An example wrapper function to assist you
'*******************************
Function GetColumns(Byval strConnectionString , ByVal as_tablename )

Dim lvar
Dim intRecord
Dim cmdcolumnlist
Dim rscolumnlist
Dim cn

      set cn = Server.CreateObject("ADODB.Connection")
      cn.Open strConnectionString
      set cmdcolumnlist = Server.CreateObject("ADODB.Command")
Set cmdcolumnlist.ActiveConnection = cn

cmdcolumnlist.CommandText = "sp_columns"
cmdcolumnlist.CommandType = adCmdStoredProc
cmdcolumnlist.Parameters.Refresh
'Check the return codes
cmdcolumnlist.Parameters(1).Value = as_tablename
cmdcolumnlist.Parameters(2).Value = "dbo"
cmdcolumnlist.Parameters(3).Value = "TestDatabase"
Set rscolumnlist = cmdcolumnlist.Execute()
'return the recordset in a variant array
lvar = rscolumnlist.GetRows()
GetColumns = lvar
cn.Close

Set cn = Nothing
Set rscolumnlist = Nothing
Set cmdcolumnlist = Nothing
End Function

You could now use this wrapper function
<%
Dim ivar_test
Dim i
ivar_test = GetColumns("FILEDSN=test.dsn", "Employees")
'lvar is a 2D array
For intRecord = 0 to Ubound(lvar , 2)
Response.write lvar(1, intRecord) & " " & lvar(2, intRecord)
'......your code for manipulation
'please remember you could have easily 'returned a ADODB or ADOR Recordset and manipulated the recordset.

Next
%>
'Hope this helps.
