I know these 2 commands
sp_who and sp_who2 → knowing who are updateing
DBCC log (DB_NAME,4) → I can't really understand these information..
just wondering does there exists a log file, so we can check who have updated database from it?
We can catch the error log information by use EXEC xp_readerrorlog. I am just wondering is SQL have other types of log for us to reference information
I didn't wrote trigger for my tables... one table was missing, would it possible to know when the table was be deleted by some kind of transaction log?
how to write a code to check the Transaction ID from SQL Table in view state gridview for each row data ?
For Example, select transID from Table.Current ID is 14481.
So now when i add in the view state grid view, it show the same trans number
Is it any method to write the + values in add row function in c# to increase the values ? as below is the c# code.

I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old
using (TransactionScope transaction = new TransactionScope(TransactionMode.New))
{
Post p = Post.Find(id);
p.Status = Status.New; // new status set here
p.Update();
SessionScope.Current.Flush();
transaction.Flush();
transaction.VoteCommit();
}
outsidePost.Refresh();
// refresh doesn't get the new status, status is still Status.Old

I have a multiple database operation, Have three tables (MSsql) and need to delete one row in each table in one operation, one after another. (Three functions, three rows of code). Everything is working as it should be, recently I was advised to use a transaction scope, which should guarantee the safety of deletion from all 3 tables together.
Here is my new code:

Locally all worked just fine, the transaction scope worked well, but when I have uploaded my application to my hosting server, I got an error of: The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025).I talked with the host support, they tried to do something, then I got this error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
After a 2 days, They have contacted me, they said it is not possible to disable some restriction, that will allow an access to this operation, because I'm using shared hosting, and I need to upgrade my plan to VPS. VPS is a very expensive for me, and I can't afford it, What I'm looking is a some similar way of doing the same operation as transaction scope do, that may work at my hosting, At least I would like to try something else. Is there any additional way for the transaction scope?

I develop an application using LINQ to SQL. Recently I deploy the application on server and starts performance testing using WAPT for 100 users. Unfortunately, 90 requests are failed while placing an order and only 10 are passed. I analyse and found that for every failed request I got an error "System Exception: Transaction (Process Id 68) was Deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction."

I have to write stored proc to get the daily transaction for a specified date. Right now what i do is everytime i log a transaction in table3 I update table 2 with the count. Then i use table 2 to write the stored proc and to get the desired result. I have pasted my stored proc below with the output. My problem is when another subsystem is added in the AppInfo table i need to update my stored proc because i have hardcoded the subsystem name.

I want to generate 30,000 cards and each card must be duplicate check with database. In my card, there are 2 things. Serial No and CardID. If any card already exists then I generate another card id but with the same serial no.
So how faster way I can generate 30,000 card with duplicate check? Which one I have made application, it takes about 25 minutes to insert.
I have a stored procedure which fetches data after joining 8-9 tables and inserts that into a temp table. It was running fine till now, but now when the amount of data fetched have exceeded 20000, the SP is breaking. I have debugged the sp and found that this main query is failing after returning arround 15000-16000 records.
The error message says Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I know what is deadlock, but when i checked with SP_LOCK stored proc i only found that my process is running on database only. So how is this getting deadlocked when there are no other processes running simultaneously on server.

topic - topicid (pk),sub, message (content), catid(fk), createdby, createddate, updatedby, updatedon, viewers( count of views)
post - postid(pk), topicid(fk), post (content), createdby, createddate, updatedby, updatedon.
As i told in my last post, I am designing a forums website. I am not able to design the query to retrieve the topics for a category for example say catid=1. I want to display it in a grid view as done in every forums.
I made some query :
SELECT Topic.Sub, Topic.CreatedBy,COUNT(Topic.viewers) from topic where catid=1
group by Topic.Sub,Topic.CreatedBy
This is for retrieving the topic name from the subject and the createdby giving the topic starter and the total no. of views of that topic.
Now i want to make a query from the post table displaying the last post in the topic and if the post does not exist, i want to display the 1st post from the topic table as the last post done.
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.
There are tons of references for this error message on the Web, but I can't figure it out. The problem is that the application works fine when I run it locally or when deployed to other servers. There is just one server where I get this error during a post back from an Update panel (it is supposed to populate and open a popup panel). There is no Response.Write() anywhere in the code and the other either. I think. The next thing I will try is install the remote debugger. In the meantime, can someone tell me how to check if server trace is enabled (IIS 6)?
I am very new to this and have watched a lot of the videos. While trying out VWD2010 and SQL2008 Express, I come across many things, I just don't know how to do. Here is the latest:
I have a Table
UserId - Int - AutoIncrement
FirstName - Var(10)
LastName - Var(10)
I also have an ASP web page that allow the user to enter a first name and last name. It also has a button to submit. What I would like to do is have a Select statement check to see if the name already exists, then send a comment back to the user via a label. If it doesn't exist, then I would like to Insert the info and then again inform the user via label.
SelectCommand="SELECT COUNT (UserId) FROM Users WHERE ((FirstName=@FirstName) and (LastName=@LastName))"
InsertCommand="INSERT INTO User(LastName, FirstName) VALUES (@FirstName, @LastName)"
<InsertParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</SelectParameters>
On the code behind, I get lost. (Obviously this doesn't work, but I don't know how to go about getting a results back. Protected Sub bSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bSubmit.Click

(check return value, if <>0 then

else

end if)
End Sub
