ADO and SQL PREPARE

["Michael Naughton" <michael_naughton@xxxxxxxxxxxx>]

I'm assuming this is a Domino question -- if not, I hope someone can point me in the right direction. I'm having trouble getting a SQLRPGLE stored procedure to return results to a Domino agent when the stored procedure uses a prepared SQL statement.

I have set up a test where a Domino agent, using ADO, runs a stored procedure on the iSeries that returns a recordset. The agent then lists the rows that were returned. The following code in the stored procedure works fine:

      /free
               Exec SQL
                DECLARE C1 CURSOR WITH RETURN FOR
                SELECT CMPNAM FROM RCO ORDER BY CMPNAM DESC;

               Exec SQL Open C1;
      /end-free 

but the following code causes an error in the agent saying there's a problem opening the recordset:

      /free
			SQLTXT = 'SELECT CMPNAM FROM RCO ORDER BY CMPNAM DESC';
			
               Exec SQL
                PREPARE sqlstmt FROM :SQLTXT;

               Exec SQL
                DECLARE C1 CURSOR WITH RETURN FOR sqlstmt;

               Exec SQL Open C1;
      /end-free 

Interestingly (oddly?), both work fine if I call them directly in iSeries Navigator's Run SQL Scripts.

The relevant code in the agent is:

	''  Create the command object
	Set adoCmd = CreateObject("ADODB.Command")
	Set adoCmd.ActiveConnection = ADOConnection
	adoCmd.CommandType = adCmdStoredProc
	
	cmdString ="MYLIB.MYTESTPROC"
	adoCmd.CommandText = cmdString

	'' Create the ADO record set
	Set adoRS = adoCmd.Execute()

	cnt = 0
	'' Check if result set is open
	If (adoRS.State = adStateOpen) Then
		'' Check if result set contains any rows
		If (Not adoRS.EOF)  Then
	
			While (Not adoRS.EOF) 
				cnt = cnt + 1
				Print adoRS.Fields("CMPNAM").Value & |<br />|	
				
				adoRS.MoveNext
			Wend									'' (Not adoRS.EOF)
			
			Print |<br /> | & CStr(cnt) & | rows found <br /> |
			
		Else
			'' No records in recordset
			Print | No rows found! <br />|
		End If		'' (Not adoRS.EOF) <> "0") 
		
	Else
		'' Recordset was not open
		Print | There was a problem opening the recordset! <br />|
	End If		'' (adoRS.State = 1)

and the stored procedure is created with the following command:

create procedure MYLIB/MYTESTPROC        
language rpgle                          
parameter style general                 
not deterministic                       
reads SQL data                          
result sets 1                           
external name 'MYLIB/MYSRVPGM(MYMOD)'

Does anyone have any idea what is going on?

Thanks very much in advance,
