java - What is lazy loading in Hibernate? -


What is sluggish loading in Java? I can not understand the process. Can someone help me understand the lazy loading process?

Say that you have parents and parents and children's children should be in hibernation now children "Lazy-load", which means that this does not actually load all the babies while loading parents, instead, when they are requested to do so, it loads them. Either it can express or request, and this is more common, when you have a child When you try to reach the area, then hibernation will be automatically loaded.

Lazy-loading can help improve performance significantly because you often need children and therefore they will not be loaded.

Also beware of n + 1- problem when you use the collection, hibernation will not actually load all the children. Instead, it will load each child individually. When the collection starts again, it causes a query for each child, to avoid this, you can run hibernate for all children to load together, e.g. By calling parents child (). Shape ().

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
