ORA-24338 statement handle not executed

今天收到开发人员发来的mail,  程序在调用function 的时候，偶尔会报错，大多数时候都正常， 具体报错如下 ： 

12/8/2010 5:54:34 PM - Checking MERGED DFMS with Servicetag [128QPN1]
12/8/2010 5:54:34 PM - Creating Dataset
12/8/2010 5:54:34 PM - Initializing WebReference
12/8/2010 5:54:34 PM - Web reference creted, calling GetSn option
12/8/2010 5:54:34 PM - WS returned: ORA-24338: statement handle not executed

12/8/2010 5:54:34 PM - Try to fill out the datagrid with the first table
12/8/2010 5:54:34 PM - Exception Caught:System.NullReferenceException: Object reference not set to an instance of an object.
   at TEST_DFMS.Form1.button4_Click(Object sender, EventArgs e)

 

ORA-24338 statement handle not executed
游标没有执行

Cause: A fetch or describe was attempted before executing a statement handle.
没有执行游标就从上面取数

Action: Execute a statement and then fetch or describe the data.
做好异常控制,如果分析或执行出错的时候做好异常控制,php,jsp页面处理的时候比较容易出错.
