"INSERT INTO" - Inserting New Data Rows
This section describes how to insert new data rows with INSERT INTO statements.
INSERT statements are used very often by database applications to insert new data rows into tables. The syntax of INSERT statements is very simple. You need to provide a list of column names and a list of values for those columns. There are a couple of simple rules about INSERT statements:
INSERT statements should be executed with the executeUpdate() method. Here is a simple program that insert some rows into my table Profile:
/* OracleMultipleInserts.java * Copyright (c) HerongYang.com. All Rights Reserved. */ import java.util.*; import java.sql.*; public class OracleMultipleInserts { public static void main(String [] args) { Connection con = null; try { // Setting up the DataSource object oracle.jdbc.pool.OracleDataSource ds = new oracle.jdbc.pool.OracleDataSource(); ds.setDriverType("thin"); ds.setServerName("localhost"); ds.setPortNumber(1521); ds.setDatabaseName("XE"); // Oracle SID ds.setUser("Herong"); ds.setPassword("TopSecret"); // Getting a connection object and statement object con = ds.getConnection(); Statement sta = con.createStatement(); int count = 0; // insert a single row using default values count += sta.executeUpdate( "INSERT INTO Profile" + " (ID, FirstName)" + " VALUES (1, 'Herong')"); // insert a single row using provided values count += sta.executeUpdate( "INSERT INTO Profile" + " (ID, FirstName, LastName, Point, BirthDate)" + " VALUES (2, 'Janet', 'Gates', 999.99, '13-Oct-1984')"); // insert rows with loop with random values Random r = new Random(); for (int i=0; i<10; i++) { Float points = 1000*r.nextFloat(); String firstName = Integer.toHexString(r.nextInt(9999)); String lastName = Integer.toHexString(r.nextInt(999999)); count += sta.executeUpdate( "INSERT INTO Profile" + " (ID, FirstName, LastName, Point)" + " VALUES ("+(i+10)+", '"+firstName+"', '"+lastName+"', " + points+")"); } // How many rows were inserted System.out.println("Number of rows inserted: "+count); // Checking inserted rows ResultSet res = sta.executeQuery( "SELECT * FROM Profile"); System.out.println("List of Profiles: "); while (res.next()) { System.out.println( " "+res.getInt("ID") + ", "+res.getString("FirstName") + ", "+res.getString("LastName") + ", "+res.getDouble("Point") + ", "+res.getDate("BirthDate") + ", "+res.getTimestamp("ModTime")); } res.close(); sta.close(); con.close(); } catch (Exception e) { e.printStackTrace(); } } }
Notice that Random class was used to generate some random strings and numbers.
If you run this program again, 12 records will be inserted into "Profile" table.

By the way, if you are getting the "no privileges on tablespace 'USERS'" exception, you probably forgot to give "Herong" enough space in the tablespace 'USERS'. So run the "ALTER USER Herong QUOTA 10M ON USERS;" to fix the problem.
