sql - Can MySQL convert a stored UTC time to local timezone? -


Can MySQL convert a stored UTC time into a local timezone: Ed time directly in a general selection statement?

Suppose you have some data with Timestamp (UTC). 

  create table 'some data tab' (`id`in (11) null auto_interpretation,` value float tap default '0', 'date', '0000-00-00 00:00:00 ', Primary Key (`ID`) by default is not zero time zero

Then when I select 

 " value, some dates Date from ";

I definitely get all the dates in their stored UTC form.

But we say that I want to do them with other timezones (DST), can I add some magic to selected queries so that I get all the dates in the chosen time zone? 

  Select "value" from the charetate, the timezone (date, "Europe / Berlin");

Or let me head it in some other layer

Thanks Johan

If your MySQL installation is done If you allow to use CONVERT_TZ, this is a very clear solution, this example shows how to use it. 

  SELECT CONVERT_TZ ('2010-01-01 12:00', 'UTC', 'Europe / Stockholm')

However I do not know that this is a good way because some MySQL installs this function Use it carefully.

Yes, convert_ts function.

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...
