I have a stored procedure that I want to call from my VB program. I have two ways of programming it and I want to know the difference. Mostly it is thew way the parameters are set.


**************** Method 1 String Parameters*********  

cmd.CommandText = "AlltestProc " & b & ", '', '', " & f & ", ''"
cmd.CommandType = adCmdStoredProc

********************************************************

+++++++++++++ Method 2 Using Command object ++++++++++++

  cmd.CommandText = "AlltestProc " & b & ", '', '', " & f & ", ''"
  cmd.CommandType = adCmdStoredProc
'  cmd.Parameters.Append cmd.CreateParameter("pint", adInteger, adParamInput, , 1)
'  cmd.Parameters.Append cmd.CreateParameter("pVarchar", adVarChar, adParamInput, 4, "This")
'  cmd.Parameters.Append cmd.CreateParameter("pChar", adChar, adParamInput, 3, "OKY")
'  cmd.Parameters.Append cmd.CreateParameter("pTinyInt", adTinyInt, adParamInput, , 3)
'  cmd.Parameters.Append cmd.CreateParameter("pReturn", adVarChar, adParamOutput, 30, "")
  Set rs = cmd.Execute

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The first method seams to be easier.

The second method is the best way of doing this. You are specifying the correct types to pass to the Stored Procedure so there will be no ambiguity when they are passed into it.

You can also use SQL Execute to call your procedure, like

Set rs = con.Execute("EXECUTE sp_name, paramnumber, 'paramtext', moreparams")

This returns a forward-only cursor and may not be applicable for all situations but it's quick and easy.
