sql - Deleted some Oracle DBF files by mistake - how can I tell Oracle XE to forget about them? -


So I accidentally removed some DBF files (specific to my tablepace only), fortunately I was about to start loading data. Nothing has been lost in it, except that the tablespace can not be created again.

If I run:

Select a name from v $ datafile;

The DBF files that I have removed in the results.

I tried to run an order found on the Internet so that it was relevant to remove the dbuff files to the obelisk: 

  changing the database data file & lt; A_DBF_file_that_no_longer_exists & gt; ' Offline Drop;

And the result is: 

  Changing the database data file succeeded

However the deleted data file is still back When I try to create a new tablepace when I run the selection statement, I get an error: 

  SQL error: ORA-01543: The location of the tables 'my_tablespace_name' already Exists 01543. 00000 - "The location of the tables '% s' already exists * Cause: Try to create a tablepace * A new name for the new tablepace. *   
 
 
 Leaving the affected tables will not automatically drop the tabletration from leaving the data file.  
  Drop Tables SPACE content and data including mytablespace Cascade Consultants;

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...
