We still have to address the issue of nulls blocking the anti-join (and associated) transformations. There are two ways of understanding the issue. The first is the informal observation that the anti-join is approximately equivalent to the outer join show in the previous section but the outer join does an equality comparison between the dept_no columns of the emp and dept tables, and nulls always produce problems when you start comparing them in any way other than is null or is not null. The second, slightly more formal, approach is to note the comment in the SQL Reference manual that colX not in ('A', 'B', 'C') is equivalent to colX != 'A' and colX != 'B' and colX != 'C' The string of ANDs means that every one of the individual conditions in the list must be checked and must evaluate to true for the entire expression to evaluate to true. If a single condition evaluates to false or null, then the expression is not true. As an example of the errors that can occur if you forget this, script notin.sql in the online code suite sets up a case with the following results: select * from t1 where n1 = 99; N1 V1 ---------- -------------------99 Ninety-nine 1 row selected. select * from t2 where n1 = 99; no rows selected select from where * t1 t1.n1 not in ( select t2.n1 from t2 )

Inside main(), we invoke _validateProgramInputs() (defined later), which performs simple input validation and prints program usage if required. We then store the three command-line parameters in string variables: _validateProgramInputs( args ); String selectedOption = args[0]; String username = args[1]; String password = args[2]; The next step is to get the database connection within the try catch block. Connection conn = null; try { // get connection conn = JDBCUtil.getConnection("benchmark", "benchmark", "ora10g"); If the first parameter is nobind, we invoke the method _authenticateWithoutUsingBind Values(), which performs the authentication without using bind variables. Otherwise, it invokes _authenticateUsingBindValues(), which validates the username and password using bind variables. We end the main() method with the usual catch and finally clauses: if( NO_BIND.equals( selectedOption ) ) { _authenticateWithoutUsingBindValues( conn, selectedOption, username, password ); } else { _authenticateUsingBindValues( conn, selectedOption, username, password ); } } catch (SQLException e) { // handle the exception properly - in this case, we just // print a message and roll back JDBCUtil.printExceptionAndRollback( conn, e ); } finally { // release JDBC resources in the finally clause. JDBCUtil.close( conn ); } } The definition of _authenticateWithoutUsingBindValues() follows. The main point to note is that the query statement string is computed by concatenating the input username and password to the query string. We use the Statement class to emphasize that we are not using bind variables in this case.

If we find no records matching the input username and password, we print a message indicating that the authentication failed. Otherwise, authentication succeeds and a message to that effect is printed: rset = stmt.executeQuery( verifyStmtString ); while( rset.next() ) { int count = rset.getInt(1); if( count == 0 ) System.out.println("Invalid username and password - access denied!"); else System.out.println("Congratulations! You have been " + "authenticated successfully!"); } } finally { // release JDBC-related resources in the finally clause. JDBCUtil.close( rset ); JDBCUtil.close( stmt ); } } The following method, authenticateUsingBindValues(), also executes the same select statement, except this time we use a PreparedStatement object and bind our input parameter values: private static void _authenticateUsingBindValues( Connection conn, String selectedOption, String username, String password ) throws SQLException { PreparedStatement pstmt = null; ResultSet rset = null; try {
