c# - MySQL Split to use in "SELECT WHERE IN" statement -


I'm putting some MySQL sites in hopes of finding something that will allow me to turn it on: 

  var parameter = "a, b, c, d"; // (commas-delimited values ​​can be any number)

In this (assuming that my parameters are in some way the values ​​you are seeing in these blocks ): 

  SELECT * mytable WHERE from parametipe ('A', 'B', 'C', 'D');

But I have not had much success! The best site I've found:, which discusses the splitting of strings based on a delimiter (',' in my case), although this has not been answered ...

Anyone In a good way of dividing a comma-delimited strings, in the context of the strings that can be used in this context?

This may not have all the flexibility you need, but the MySQL function may be sufficient. For example: To select: 

  SELECT * mytable WHERE FIND_IN_SET (from parametertype, 'a,), there is a hard limit of up to 64 values ​​in the set. B, C, D ')! = 0

This is an example of the use of an in-line MySQL ('a, b, c, d') - it can be an emblem This is a sign that some data models are full of normalization if they are being used.

But to associate with complex information that stays out of the database, they may be easy to join, or to end (in this case).

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...
