JDBC Pertanyaan dan Jawaban Wawancara

Question: How can you create JDBC statements and what are they?

Answer:

A Statement object is what sends your SQL statement to the DBMS. You simply create a Statement object and then execute it, supplying the appropriate execute method with the SQL statement you want to send.

For a SELECT statement, the method to use is executeQuery. For statements that create or modify tables, the method to use is executeUpdate. It takes an instance of an active connection to create a Statement object.

In the following example, we use our Connection object con to create the Statement object:

Statement stmt = con.createStatement();
