方式一、批量执行预定义模式的SQLpublic static void exeBatch(Connection conn) { try {
String sql = "insert into t_example (code, name) values (?,?)";
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setString(1, "java2");
pstmt.setString(2, "java");
//添加一次预定义参数
pstmt.addBatch();
pstmt.setString(1, "360sdn");
pstmt.setString(2, "软件开发技术网");
//再添加一次预定义参数
pstmt.addBatch();
//批量执行预定义SQL
pstmt.executeBatch();
} catch (SQLException e) {
e.printStackTrace();
} finally {
closeConnection(conn);
}
}
方式二、批量执行混合模式的SQL、有预定义的，还有静态的
public static void exeBatchMixedSQL( Connection conn) {
PreparedStatement pstmt =null;
try {
String sql = "insert into t_example (code, name) values (?,?)";
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setString(1, "java");
pstmt.setString(2, "360sdn");
//添加一次预定义参数
pstmt.addBatch();
pstmt.setString(1, "360sdn");
pstmt.setString(2, "软件开发技术网");
//再添加一次预定义参数
pstmt.addBatch();
//添加一次静态SQL
pstmt.addBatch("update t_example set code= '360.com' where code='360sdn'");
//批量执行预定义SQL
pstmt.executeBatch();
} catch (SQLException e) {
e.printStackTrace();
} finally {
closeConnection(conn);
}
}
方式三、执行批量静态的SQL//执行批量静态的SQL
ublic static void exeBatchSQL(Connection conn) {
try {
Statement stmt = conn.createStatement();
//连续添加多条静态SQL
stmt.addBatch("insert into t_example (code, name) values ('java', '360sdn.com')");
stmt.addBatch("insert into t_example (code, name) values ('360', '360sdn')");
stmt.addBatch("delete from t_example where code='java'");
stmt.addBatch("update t_example set kind = '360data' where kind='360'");
//批量执行不支持Select语句
// stmt.addBatch("select count(*) from t_example");
//执行批量执行
stmt.executeBatch();
} catch (SQLException e) {
e.printStackTrace();
} finally {
closeConnection(conn);
}
}
