datetime - how to convert date in oracle -


मेरे पास के प्रारूप में एक तारीख है: 

  27-मई -09 12.00 00.000000 पूर्वाह्न

मैं इसे इसमें परिवर्तित करना चाहता हूं: 

  05/27/2009

मैंने To_char (my_date_variable, 'mm / dd / yyyy') हालांकि यह मुझे संख्या रूपांतरण त्रुटि के लिए वर्ण देता है

मैं इस तिथि को बदलने के लिए क्या कर सकता हूं? / P>

my_date_variable को इस रूप में घोषित किया गया है: 

  my_date_variable VARCHAR2 (40);

आपको पहले my_date_variable से VARCHAR2 कन्वर्ट करना होगा से TIMESTAMP : 

  to_char (to_timestamp (my_date_variable), 'MM / डीडी / YYYY')

'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...
