问题 I have a table - emp_record which has 40,000 records And I want to fetch the records from java code and below is the requirement - At a time only 1000 records should be returned In the next hit next 1000 records continue till all the records exhaust The SQL query should not be nested, like select * from( SELECT a.*,rownum rn FROM distributor a) WHERE rn >= 3000 and rn < 4000; Any sort of help is much appreciated. 回答1: This sounds very artifical as 40.000 records is nothing. I would just read

问题 I want to use jQuery to trigger a page refresh, only once, when a media query has been triggered. This is how I detect my media query: function media_query(obj) { size = obj(); if (size != currentSize) { if (size == 'mobile') { location.reload(); currentSize = 'mobile'; } if (size == 'tablet') { location.reload(); currentSize = 'tablet'; } if (size == 'laptop') { currentSize = 'laptop'; } } }; $(window).resize(_.debounce(function () { media_query(mqCSS); }, 10)); $(window).load(function () {

问题 What exactly does "fixups" do when applied on a section? In a fasm sample i found the following section delcaration and i'm really not sure what the fixups attribute does, i couldn't find much information on that in the fasm documentation. section '.reloc' fixups data readable discardable if $=$$ dd 0,8 ; if there are no fixups, generate dummy entry end if 回答1: This appears to be a workaround for a bug in how FASM generates PECOFF DLLs. The .reloc section only applies to PECOFF images (EXEs

问题 I have a df attached and I would like to create a loop that would apply a specific sequence based on conditions in column "x9" . I would like to be able to set the sequence myself so I can try different sequences for this data frame, I will explain more below. I have a df of losses and wins for an algorithm. On the first instance of a win I want to take the value in "x9" and divide it by the sequence value. I want to keep iterating through the sequence values until a loss is achieved. Once a

问题 I'm building a POC multi-tenant app using IdentityServer 4 on asp.net core as the middleman between my client app and Azure Active Directory using openIdConnect. Is there a way to trigger the admin_consent flow when a user logs in from a new AAD tenant which is not yet authorized to use the app? This Azure sample shows how to perform a manual consent using a controller on the client site which builds the AAD Uri from scratch, but I'm shooting for an experience where a user from a new
