sql - stored procedure column value determined by value of another column -


I have some data like this. 

  Date, amount, value 200 -10-12, 20, 15.43, 2009-10-13, -10, 6.98

I have a stored procedure Which will return these columns as well as create a new column which indicates whether the amount was positive or negative, so the last result of the process would be something like this. 

  date, amount, value, results 2009-10-12, 20, 15.43, positive 2009-10-13, -10, 6.98, negative

How can this be done? This is a SQL 2008 ENT DB. 

  select date, amount, value, case when zodiac & gt; 0 then 'positive' when the amount is & lt; 0 then #_table_or_negative to #table
as the 'negative' end

'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...
