mysql - proper way to delete album and its media and sub album and its media -


Will the album be the proper way to delete the sorted data with your media?

Would I just start looping and find all sub album ids and want to delete thous and create a query to delete all media related to that album id.

This query may be loaded in performance if the data is too many for one or one album

The structure of my database: 

  ** Album ** album_id name parent_id ** media ** media_id album_id name  

  Remove from album, media WHERE media.albumID = albums.albumID and (albums.parentID =? Or album. AlbumID =?)

This is a simple way, assuming that your data Triggers or relationships have not been defined Hard to give your best answer without knowing more about your specific database structure; However, with other situations, why are you better than doing this as a single SQL statement? This protects your data integrity, otherwise you have to issue locks on various tables, while your software manually deletes specific entries (which is also a solution, but knowing more, I do not want to recommend ).

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...
