Connection object, the next step is to create a Statement object.
The createStatement method of your JDBC Connection object returns an object of the JDBC Statement interface.
Below is an example of how to create the Statement object:
Statement stmt = conn.createStatement( );Note that there is nothing Oracle-specific about this statement; it follows standard JDBC syntax.
Connection object first gets created, it is simply a direct link to the database.
You use a Connection object to generate implementations of java.sql.Statement tied to the same database transaction.
java.sql.Statement contains methods to execute SQL statements directly against the database and to obtain the results.
Statement objects.
If the same SQL statement is executed many times, it is more efficient to use a PreparedStatement object.
ResultSet object per Statement object can be open at any point in time.
Therefore, if the reading of one ResultSet object is interleaved with the reading of another, each must have been generated by different Statement objects.
ResultSet object if an open one exists.
