java - how to append a list in href url? -

-

I want to add a list to URL which is an href, how can I do this and how do I code it .getParameter () ? Or a complete bean object in the URL?

Use the same name for each item, create something like this: http: / /example.com/somepath?amt=1&amt=2&amt=3 .

And then you can use HttpServletRequest.getParameterMap () . Or alternatively, you can use the HttpServletRequest.getParameterValues ​​(name) . You may want to use the latter by specifying the name, for example, 

  string [] amts = request.getParameterValues ​​("amt");

By the way, getParameterMap () gives you a map object in the form of the parameter names as it will have all other request parameters as well as your 'AMT'. 

  Map map = request.getParameterMap (); String [] amts = map.get ("AMT");

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
