Subject Re: Sybase proc with return value, results, IN & OUT params
Date Thu, 12 Jan 2006 19:45:31 GMT

It works in JDBC and  code is shown below.  It prints out all -ie. error code, message, return
value and either sql error message ( no results) or result set   
Note: It also works (ie returns all desired values as in JDBC ) in ibatis only when the query
succeeds ie have result sets and passes any paramter condition checks.  But fails/exception
 when the proc call   does not pass parameters check  or no results - it then DOES NOT  return
the OUT param values and  Return Value set in the proc.

Thanks, 
Balaji

  Connection con = null;
  CallableStatement stmt = null;

  try {
    InitialContext ctx = new InitialContext();
    DataSource ds = (DataSource) ctx.lookup("java:comp/env/caresDB");
    con = ds.getConnection();
    stmt = con.prepareCall("{? = CALL proc_get_applist(?,?,?)}");
    stmt.registerOutParameter(1, Types.INTEGER);
    stmt.setString(2, "testuser");
    stmt.registerOutParameter(3, Types.VARCHAR);
    stmt.registerOutParameter(4, Types.VARCHAR);
    result = stmt.executeQuery();
  } catch (NamingException nex) {
   System.err.println("Naming Error: " + nex.getMessage());    
  } catch (SQLException sqlex) {
   System.err.println("SQL Error: " + sqlex.getMessage());
   System.out.println("Return Value:" + stmt.getString(1));
   System.out.println("ErrorCode:" + stmt.getString(3)); 
   System.out.println("Error Message:" + stmt.getString(4));
  }

  This may be one of those cases where you have to write it in JDBC....even as just a test
to see if it works with your database driver.  Once that's done, you can post it here and
we can see if there's anything iBATIS is doing to cause the problem.  

  At first glance, I'm wondering if it would even work with plain old JDBC (it should, but
the driver may not support it)...

  Cheers,
  Clinton

    I am trying to call a sybase stored proc which returns results set and a return value,
has input paramters & output parameters. 

    I need to know how to to get the 
    1. return value ( 0 on success, -1 on failure)
    2. out parms values - as_error, as_error_msg
    3. Result set list ( if success)
