c# - SharePoint Custom Web Part throws SELECT permission denied on object 'xxx', database 'yyy', owner 'dbo' -


I created a custom web part in SharePoint 2007 using VS 2008 on dev server. It uses SQL DB everything works fine on my server, which was created by the backup client with Test DB.

Now I'm taking it to the customer's production server. I was able to deploy, install and activate it.

But when I want to add web part to the page, it throws a dialog box "An error occurred while executing the command definition. Internal exceptions for details".

It is that I am looking into LOG file: ... Permission denied on selection object 'xxx', database 'yyy', owner 'dbo' ... < / P>

The web part uses DB using escalated realms, i.e. using the portal app pool service account. This account has the proper authority to reach DB. I do not understand what might be the cause of the problem.

With any help, find out what the cause of the error is!

Edit:

To add the pasted formatting to the code comment, include: 

  SPSecurity.RunWithElevatedPrivileges (Rep ({{WAStockBinEntities} Reference = New WAStockBinEntities ()) by using {var userStockBin = (1view_SP_StockBin in the context where stockbins.ADName = = Select CurrUserName Stockben) .OOLIT (). FirstOr Default (); StokerumNumber.txt = Userstock Bin. StuckRoom; Binnumber. Text = Userstock bin.bin;}});

SPSAquiryRanvith elevated Privilege does not affect user That LINQ uses the database to access I will look at the connection string that LINQ is using to access the database and ensures that the user specified in the connection string is the database permission

< P> You can check the connection string The call is being used by connection.connection string data reference property. 

 using  (WAStockBinEntities Reference = New WAStockBinEntities ()) {reference reference.Connection.ConnectionString; }

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...
