paging

问题 I have a query in SQL Server 2012 that should get back a number of records based on the page size I specify and the page it is on. It looks like this: SELECT LocID, LocName FROM Locations ORDER BY LocName OFFSET @PageNum ROWS FETCH NEXT @PageSize ROWS ONLY The code is pretty simple. What I need to do, though, is put that into a function to return the paging correctly. However, I could also be needing all records back from this function, so I need to have the option of calling the function

问题 In 64-bit Linux, IA-32E paging is used with 4 levels of paging structures ( PML4 / PDPT / PD / PT ). The entries in the former three structures give the physical address of the corresponding next structure. My question is that will the physical addresses of all these paging structures be mapped in the paging table? If they are mapped, in which mode ( User / Supervisor )? Thanks very much! I captured some specific memory addresses which a vcpu have accessed during a period in KVM . These

问题 i'm trying to implement paging in xml using this code and got around to making it work. while it works perfectly, there is a small issue, that when i click on the NEXT button, it keeps reloading the page with the same initial records. it does not take the user to the next page. i came across this link wherein the poster had a similar issue, and it seems from the answers parameters need to be passed. however, the guy in that link was using MM_XSLTransform, while i'm not. hence when i try to

问题 I'm using jqGrid in my project and ran into a strange paging issue. I can click on the next page button and go from page 1 to page 2, but any other paging buttons I push after that I get stuck on page 2 and can't go to other pages. I can however type in a page number, hit enter and then it will update the page displayed. I have pasted the jqGrid code below. jQuery(document).ready(function(){ jQuery("#groupsTable").jqGrid({ jsonReader: { root:"rows", page:"page", total:"total", records:

问题 I have approximate 50000 row gridview.and i set the pagesize 20 grid view.so how we can find the last row gridview.If we do next then it takes more time. 回答1: If I get your question right, you want to shift to last page from first page. What you can do is when you are binding the gridview save number of rows in your data source in viewstate : viewstate["rowCount"]=number; Then use a seperate link for navigating to last page which fires pageindexchanging event. On that event you can calculate

问题 I am analyzing the effect of allocation across virtual pages while creating a 2-D array of dimension PageSize x PageSize. My machine's page size is 4096. I have an array of 4096 integer pointers(columns), pointing to 4096 integers(rows). I want to begin the allocation for the first integer pointer at a new virtual page. How can I identify if the current memory location is a new page or not? Once, I have identified that, I believe I can write some garbage values and move the pointer to a new

问题 I am using PagedList.MVC for paging in my MVC application.So first i am on home page and when i fill search bar and submit the form it post the Model on search method , which is as bellow. public ActionResult GetSearchdProperty(int? page,SearchModel objSearch) { var objProperty = db.re_advertise.OrderBy(r => r.id); return View("SearchedProperty", objProperty.ToPagedList(pageNumber: page ?? 1,pageSize: 2)); } So this redirect to search page with searched criteria results. Now when i click 2nd

问题 in a paged-segmented system we have the virtual address of 32 bits and 12 bits for the offset,11 bits for segment and 9 bits for page number.the how can we calculate the page size ,maximum segment size and maximum number of segment size? 回答1: 12 bits are reserved for offset, so the page size is 2^12 = 4KB 9 bits are reserved for page number, so each segment can contain 2^9 = 512 pages Each segment can grow up to size of (# of pages) * (pages size), so maximum segment size is 512 * 4K = 2M For
