/*
 * This sample shows how to insert data in a table.

// You need to import the java.sql package to use JDBC
import java.sql.*;

class InsertExample

      DriverManager.getConnection ("jdbc:oracle:oci8:@", "scott", "tiger");

    // Prepare a statement to cleanup the emp table
    Statement stmt = conn.createStatement ();

    // Add LESLIE as employee number 1500
    pstmt.setInt (1, 1500);          // The first ? is for EMPNO
    pstmt.setString (2, "LESLIE");   // The second ? is for ENAME
    // Do the insertion
