mysql - Help with database design -


I would like some advice on designing my database tables for a small project, on which I am working. In this system, assume that I have article , sub-article , and comments .

Each article can have sub-articles, both articles and sub-articles can have comments. I am considered to be an AutoIncreiting Inti Primary Key for each table (such as article ID, sub-article, and comment id). Sub-articles will contain an article which is in the form of a foreign key in the article table etc.

But for some reason I have the perception of the unique ID of the world. What would be the best way to implement this? Should each table have a uuid primary key and the first mentioned id column should be used as a regular column (since I still would like a logical number associated with each object)? Or should I create the main object mapping table with the uuid ?

Any suggestions on the good way to implement it will be appreciated!

I have tables now articles and comments , and there will be a null-eligible ParentArticleID field in the paragraph table. 

  article ------- Article ID (int PK) guardian article int FK) ... Comment ------- Comment ID (Ent PK) Article ID (int FK) ...

If you need a GUID, then do not use it as a PK because it will not display even during indexing. Create different fields for the GUID.

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...
