如何在MySQL中的存储过程中生成异常？例如:

CREATE PROCEDURE SALES()
BEGIN

STATEMENT...
STATEMENT...
STATEMENT...

IF (PRICE >= 500) THEN
/** THROWS AN EXCEPTION....  
    WHAT DO TO STOP THE PROCEDURE. **/
END IF;

STATEMENT...
STATEMENT...
STATEMENT...

END;

在MySQL中我认为没有办法在存储过程中抛出异常,但我可以通过从不存在的表中选择来强制错误.例如:

IF (PRICE > 500) THEN
    /*throw the error here*/
    SELECT * FROM price_greater_than_500_in_throw_exception;
END IF;

有更优雅的方式吗？

谢谢.

我有一个很大的问题(显然很容易解决),我已经尝试了超过24小时来创建一个函数来将数组转换为多维深度.

我的阵列是

$array = array(
    array("name" => "Root_1", "depth"=> "1"),
    array("name" => "Children","depth"=> "2"),
    array("name" => "Children", "depth"=> "2"),
    array("name" => "Children", "depth"=> "2"),
    array("name" => "Children","depth"=> "3"),
    array("name" => "Children","depth"=> "3"),
    array("name" => "Children","depth"=> "3"),
    array("name" => "Root_2", "depth"=> "1"),
    array("name" => "Children", "depth"=> "2"),
    array("name" => "Children", "depth"=> "2"),
    array("name" => "Children", "depth"=> "2")
)

我希望输出为:

$array = array(
  array("name" => "Root_1", "depth"=> "1", "children" => array(
        array("name" => "Children", "depth"=> "2", "children" => array()),
        array("name" …

尝试理解为什么在alert("hello")多次单击后不生成函数真是太棒了...有一些方法可以执行此功能吗？

请注意,使用html()涉及按钮中的id"按" 更新后不起作用.

任何的想法？请参阅:http://jsbin.com/atuqu3

JavaScript的:

  $(document).ready(function (){
      $("#press").click(function() {
          $("#relation-states").html('<select id="state" name="state"> <option value="Texas">Texas</option> </select><button id="press" type="button" title="" aria-haspopup="true" style="width: 175px;"><span>Select an item</span></button>');;
          alert("hello");
      });
  });

HTML:

  <div id="relation-states">
  <select id="state" name="state">
  <option value="New York">New York</option>
  </select>
  <button id="press" type="button" title="" aria-haspopup="true" style="width: 175px;"><span>Select an item</span></button>
  </div>
