getting this error regardless of which type of recordset I use.

If I comment
set adoRSProducts = Server.CreateObject ("ADODB.recordset")
in the function GetProductTotals(iProductId,iDate,iTime), I get
'error Object required'

Here's a sample of my code
any comments welcome!

********
dim adoRSProducts
set adoRSProducts = Server.CreateObject ("ADODB.recordset")

 if instr(1,lcase(adoRS("vDescription")),"gown") > 0 then
 set adoRSProducts = GetProductTotals(iproductid,iDate,iTime)

if adoRSProducts.eof <> true then
  loopthru(Custom)
 end if
 adoRSProducts.Close
 set adoRSProducts = nothing

elseif instr(1,lcase(adoRS("vDescription")),"hat") > 0 then
  set adoRSProducts = GetProductTotals(iproductid,iDate,iTime)
  if adoRSProducts.eof <> true then
  loopthru(Custom)

  end if
  adoRSProducts.Close
 set adoRSProducts = nothing
end if

function GetProductTotals(iProductId,iDate,iTime)

set adoRSProducts = Server.CreateObject ("ADODB.recordset")
set adoCmdCustomer = Server.CreateObject ("ADODB.command") 'another error if i comment
set adoCmdCustomer = adoCommand
   fnClearDBParameters adoCmdCustomer
   set adoCmdCustomer.ActiveConnection = adoConnection

   adoCmdCustomer.CommandText = "aspGetProducts"
   adoCmdCustomer.Parameters.Append adoCmdCustomer.CreateParameter("@iProductId", adInteger, adParamInput, , iProductId)
   adoCmdCustomer.Parameters.Append adoCmdCustomer.CreateParameter("@iDate", adInteger, adParamInput, , iDate)
   adoCmdCustomer.Parameters.Append adoCmdCustomer.CreateParameter("@iTime", adInteger, adParamInput, , iTime)

   adoCmdCustomer.CommandType = adCmdStoredProc
   adoCmdCustomer.Prepared = false

      adoRSProducts.Open adoCmdCustomer, , 2
      set GetProductTotals = adoRSProducts
  ' on error resume next
 
   set adoCmdCustomer.ActiveConnection = nothing ' Disconnect

 end function

function  loopthru(value)
dim iResult
iResult = 0
adoRSProducts.movefirst ' get the error here
do until adoRSProducts.eof
      if instr(1,adoRSProducts("vCustom1"),value) > 0 then
            iResult = adoRSProducts("Q")
      end if
adoRSProducts.movenext
loop
'adoRSProducts.Close
'set adoRSProducts = nothing
loopthru = iResult
end function

you can not use adoRSProducts.movefirst with opendynamic and Openstatic cursor type.

Actually you did not set the cursor type when you open the record set, so it took it as "adOpenForwardOnly", that why you are getting error with move first.

thanks vjsoft


 adoRSProducts.Open adoCmdCustomer, , 2 and  adoRSProducts.Open adoCmdCustomer, , 4
The 2 and 4 relates to the cursor no?

I understand it as recordset.Open Source, ActiveConnection, CursorType, LockType, Options ?

Cheers

something like?

Const adOpenStatic = 3
Const adLockOptimistic = 3

Set objConnection = CreateObject("ADODB.Connection")
Set objRecordSet = CreateObject("ADODB.Recordset")

objConnection.Open _
"Provider=SQLOLEDB;Data Source=atl-sql-01;" & _
"Trusted_Connection=Yes;Initial Catalog=Northwind;" & _
"User ID=fabrikam\kenmyer;Password=34DE6t4G!;"

objRecordSet.Open "SELECT * FROM Customers", _
objConnection, adOpenStatic, adLockOptimistic

objRecordSet.MoveFirst

Wscript.Echo objRecordSet.RecordCount

Thanks

I've changed to       adoRSProducts.Open adoCmdCustomer, ,  adOpenStatic, adLockOptimistic
and I go back to the other error on that line:

Microsoft VBScript runtime  error '800a01a8'

Object required

Hi VJ

Have been away for the weekend.

I cant see what the difference is, i.e. why my code is wrong:
 adoRSProducts.Open adoCmdCustomer, ,  adOpenStatic, adLockOptimistic

adoCmdCustomer has the correct stored proc parameters from what I can see.

What do you think is wrong?

Cheers

you missed the connection here

right syntax is:

objRecordset.Open source,actconn,cursortyp,locktyp,opt  (Reference: http://www.w3schools.com/ADO/met_rs_open.asp)
