C++ ADO stored procedure CALL format

Last Modified: 2013-11-20
All,

I am trying to pass 4 values to a EXECUTE stored procedure and then call open.  I get an exception thrown saying that it is expecting the name of the table.

Can anyone help me reformat this?

I have tried the rs.Execute("name"); command and it does not throw an exception but am not able to get at the returned values from the DB table.

thanks in advance....

regards,

Ken



CString tempstr, _tool, _pm, _device, _operation;
      _tool = "A";
     _pm = "2";
     _device"all";
     _operation = "all"    
tempstr.Format("DECLARE  @slope float, @intercept float,  @angle int\n"
"EXECUTE sp_IONMILL_BEAMANGLE '%s', '%s', '%s', '%s' , @slope , @intercept, @angle",
                              _tool, _pm, _device, _operation);

      AfxMessageBox(errMsg);
      delete pWaferDB;
      pWaferDB=NULL;
      return -99;
}

if(!rs.Open(CRecordset::forwardOnly, tempstr))

All,

Is it better to use a RecordSet or SmartPointers to call a stored procedure using C++?  I am passing 4 parameters to the in put and recieving 3 in return.

thanks in advance..

I dont't know what a smartpointer is but in VB, if you are not expecting a table back, only parameterd, then it is indeed best to NOT use a recordset - use the command object with the parameters collection.

This may be of assistance:
