select - Use a left hand value in right hand SQL comparison -

-

मेरे पास यह SELECT कथन है: 

  SELECT SUM ( Dbo.DLData.Quantity) dbo.MasterDates से dbo.DLData MasterDates पर शामिल करें। [आईडी] = dbo.DLData.DownloadID जहां dbo.MasterDates। [दिनांक] के बीच @ और @ करने के लिए और dbo.MasterDates.SiteID = @ एक्स < / Code>

यदि आप @from में प्लग इन करें, @to और @X यह काम करता है यह एक तुलना के दाहिने हाथ की ओर है हालांकि तुलना में @ एक्स को बाएं हाथ की ओर से आने की जरूरत है क्योंकि बाहर पर SELECT प्रत्येक SiteID पर परीक्षण कर रहा है सेट में इस खंड के बिना मुख्य खंड काम करता है उन्हें एक साथ जाना होगा उपरोक्त चयन बायीं तरफ, यहाँ पर पूर्ण चयन बयान है। अंततः दो वाले नियम एक साइट के प्रमुख उत्पादों को निर्धारित करेंगे।

<पूर्व> - SiteID में प्रोडक्ट्स का चयन करें SELECT dbo.MasterDates.SiteID के रूप में SiteID, dbo.DLData.Product ProductID के रूप में dbo.MasterDates JOIN dbo.DLData ON dbo.MasterDates। [आईडी] = dbo। DLData.DownloadID WHERE dbo.MasterDates। [दिनांक] के बीच में @ @ और। से ग्रुप को dbo.MasterDates.SiteID, dbo.DLData.Product हैविंग SUM (dbo.DLData.Quantity) & gt; 960 या एसएम (dbo.DLData.Quantity) & gt; (SELECT SUM (dbo.DLData.Quantity) dbo.MasterDates से dbo.DLData मास्टरडेट पर शामिल करें। [आईडी] = dbo.DLData.DownloadID WHERE dbo.MasterDates। [तिथि] @ से और @ तक और dbo.MasterDates.SiteID = @ एक्स) ORDER BY dbo.MasterDates.SiteID

आप आंतरिक बयान पर बाहरी खंड का उपयोग कैसे करते हैं? मुझे पता नहीं मैं अपनी समस्या का वर्णन करने के लिए सही शब्दावली का उपयोग कर रहा हूं।

एर्गग़ - सेट आधारित तर्क मेरे सिर में है !!

मुझे लगता है कि आप इस उपशिक्षक में शामिल होना चाहते हैं, इसे किसी भी वक्तव्य में उपयोग न करें 

  SELECT SUM (dbo.DLData.Quantity) dbo.MasterDates से जोड़ें dbo। MasterDates पर DLData। [आईडी] = dbo.DLData.DownloadID WHERE dbo.MasterDates। [दिनांक] के बीच और @ करने के लिए और dbo.MasterDates.SiteID = @ एक्स

asp.net - Javascript/DOM Why is does my form not support submit()? -

-
This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
