Hi,

here is the answer of the question.

The JDBC API is a standard that allows Java applications to perform operations against permanent storage sources, The JDBC is a pure Java API used to execute SQL statements. It provides a set of classes and interfaces that can be used by developers to write database applications.

The steps needed to execute a SQL query using JDBC:

1. Loading a database driver.

   catch(Exception x){

   System.out.println( ?Unable to load the driver class!? );
   

   }

2. Creating a oracle jdbc Connection.

3. Creating a jdbc Statement object.

4. Executing a SQL statement.

Statement statement = dbCon.createStatement(); 4-Executing a SQL statement. ResultSet rs=st.executeQuery("select * from emp"); while(rs.next()) System.out.println(rs.getString(1)); }catch(SQLException se) { } finally{ con.close(); } Thanks
