NHibernate -How to conditionally load data from a column -


We are not using FlintNubrinate. We have a table with a Blob column that we want to conditionally load. . We have referred it as 'lazy' and lazy loading is working fine. Is there a way to not load the data on that column at all on a certain condition? ? Xml version = "1.0" encoding = "utf-8", (hence the property in the related category)

For example, here is the mapping 

  & lt? & Gt; & Lt; Hibernate-mapping xmlns = "vase: nhibernate-mapping -2.2" name space = "Blah.blah.blah" assembly = "Blah.blah" & gt; & Lt; Class name = "MyDocument" table = "HEAVY_DOCS" & gt; & Lt; Id name = "id" column = "docnum" type = "decimal" & gt; & Lt; / Id & gt; & Lt; Property Name = "docname" column = "docname" / & gt; & Lt; Property Name = "Description" column = "Description" /> & Lt; Property Name = "doc_data" column = "document_data" lazy = "true" /> & Lt; / Square & gt; & Lt; / Hibernate-mapping & gt;

and the code below is getting the document 

  PrivateIlist & lt; MyDocument & gt; FetchDocuments (IList & lt; String & gt; Postal ID, bool laodData) {if (laodData!) {Docs = (Session.Query & lt; MyDocument & gt; () from the document where docId.Contains (doc.docnum) Select doc) .toList (); } Other {// if Laodetta is false, then the document is not loaded document_data} return docs; }  itemprop = "text"> 
 after the way, the way to increase the column selection by our code, using the

estimates . Adjusted code can look like this: 

  if (! LaodData) {docs = (from Session.Query & lt document; MyDocument & gt; () where docId.Contains (doc.docnum) Selection dock // full object). Olist (); } Else {Docs = (MyDocument & gt; (; MyDocument & gt;) from the document where the docId.Contains (doc.docnum) NHibernate is called the new MyDocument // selection // that is called DOCNAME = doc.docname, // projection description = doc.details, // id = doc.Id for a "doc_data" LARGE document,}) .Oolist (); }

With the projections, you can benefit from powerful anconnet, which are built in powerful result transformers which can also cover protected properties Choiroff (including relations) for changes to estimate ...

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
