方式一、批量執行預定義模式的SQL

public 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");
          //新增一次預定義引數
          pstmt.addBatch();       
          pstmt.setString(1, "360sdn");
          pstmt.setString(2, "軟體開發技術網");
          //再新增一次預定義引數
          pstmt.addBatch();       
          //批量執行預定義SQL
          pstmt.executeBatch();
    } catch (SQLException e) {
          e.printStackTrace();
    } finally {
          closeConnection(conn);
  }
 } 
 

方式二、批量執行混合模式的SQL、有預定義的，還有靜態的

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");
 //新增一次預定義引數
         pstmt.addBatch();   
          pstmt.setString(1, "360sdn");
          pstmt.setString(2, "軟體開發技術網");
//再新增一次預定義引數
         pstmt.addBatch();    
         //新增一次靜態SQL
         pstmt.addBatch("update t_example set code= '360.com' where code='360sdn'");
         //批量執行預定義SQL
         pstmt.executeBatch();
 } catch (SQLException e) {
         e.printStackTrace();
 } finally {
         closeConnection(conn);
 }
        }

 

方式三、執行批量靜態的SQL

//執行批量靜態的SQL
ublic static void exeBatchSQL(Connection conn) { 
  try { 
          Statement stmt = conn.createStatement();
          //連續新增多條靜態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'");
//批量執行不支援Select語句
//          stmt.addBatch("select count(*) from t_example");  
          //執行批量執行
          stmt.executeBatch();
  } catch (SQLException e) {
          e.printStackTrace();
  } finally {
          closeConnection(conn);
  }
        }
