I am using prepared statements and i have my code as

String query = "Insert into test (id , phone) values (?, ?)"
pstmt.setInt( 1, 19);
pstmt.setInt( 2, 12345567);

This throws an exception

but if use
pstmt.executeUpdate(); it works.

You seem to be missing:

PreparedStatement pstmt = conn.prepareStatement(query);

> pstmt.executeUpdate(query);

you cannot use placeholders if using this method, hence the exception.

The PreparedStatement has an implicit statment to execute, so passing it a query as well doesn't make much sense.  I'm not even sure why it's available, apart from the fact that PreparedStatement inherits from Statement ;-)
