Hi
I have a suprised error with Preparedstatement in JBoss with oracle 8i.
--------------------
s = "select username from user where username=?";
PreparedStatement stmt = con.prepareStatement(s);
stmt.clearParameters ();
stmt.setString(1, "demo");
result = stms.execute();
--------------------
Assume that the database already has username demo. But the above code return null
------------------------
Then I used:
s = "select username from user where username='demo'";
Statement stmt= con.createStatement(s);
result = stmt.execute(s);
------------------------
that works.
Suprisingly, when I changed back to the first solution It works too even when I restart JBOss server. But if I restart PC contains JBoss and database server. Everything is back.
Is there anybody knows this error???
regards,
Khang
