SQL Server :: Multiple Users Inserting Values In The Same Table At Same Time?
Dec 15, 2010
I have one SP in sql server which takes the data from user and inserts into three tables. My problem is if multiple users call the same SP in same time it throwing error..(I guess one user at a time can access the table and table will be locked, that is why remaning users getting error)how to handle this situation. it is a web application, so at a time so many people can call the same SP.How can many users insert data in the same table in the same time?

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.

I wanted to know how to prevent more than one user from uploading the report at a time .
This is a Windos based app written in c# . When User A clicks Upload option on one server from the menu to upload the files and at the same time when User B clicks Upload option on different server , User B should be alerted a message saying "User A's uploading is in progress,pls wait" . How to achieve this, with the code..I am thinking this logic should be kept in a stored proc, How do I write that proc?

I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List??
WHich one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
My XML will be like this
<root>
<Customer>
<CustomerID>GUID1</CustomerID>
<CustomerID>GUID2</CustomerID>
<CustomerID>GUID3</CustomerID>.....

generating logic for follwing:An option to add a range of computers based on tag numbers, for instance, user input 800101 and 800110 would add computers SYS800101, SYS800102, SYS800103, SYS 800104, SYS800105, SYS800106, SYS800107, SYS800108, SYS800109, and SYS800110. Currently the app adds a single computer at a time.Here I am using ASP.NET using C# and my backend in active directory. I had made the following code and the problem is when I enter the range like given above only the first computer in entered in the list and does not give me any error.

In short, I have 3 text box fields on an .aspx page named as follows:-
TextBoxIncident
TextBoxDate
TextBoxDescription
in addition a sql datasource is on the page which is connected to the incident table with an insert query which allows the data entered into the fields to be inserted into the database...
The Textboxincident and textboxdescription fields allow the user to enter data into them...
the TextBoxDate field is a read only and the code behind file enables the text box to show the current date and time the code im using is shown below...
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim TextBoxDate As TextBox
TextBoxDate = FormView1.FindControl("TextBoxDate")
TextBoxDate.Text = DateTime.Now
End Sub
When run in browser the textboxdate field shows the current date and time...and Once the textbox incident and text box description fields have been filled in and the submit button is clicked, the fields should be bound to MS SQL table called Incident. This did work before, however it as suddenly stopped working and now displays the following message to me:-
Arithmetic overflow error converting expression to data type datetime. The statement has been terminated.

I have to update the users based on input value..
here is my code..
<fieldset>
<legend>StudnetInfo</legend>

</fieldset>
on the same page i have couple of other Fieldset with there studentInfo with twotextboxes and two dropdownlistboxes smililarly above Fieldset..this data dynamically generated from database for each users.
so all here my intension is insted of updating each and every Fieldset i made one generic fieldset to update all other Fieldsets information
on the Generic view I have this BeginForm
<% using (Html.BeginForm("Update", "home", FormMethod.Post,
new { @id="studentid"}))
{ %>
my JsonResult is
public JsonResult Update(StudentBE e)
{
try
{
var UStatus = Generic.UpdateStudent(e.student,"","");
return Json(UStatus.ToString());
}
catch (Exception ex)
{
return Json(ex.ToString());
}
finally
{
}
}
using this I can update only one user perfectly but I need to loo update all users based on generic Filedset values?

Using SQL Server 2008, C#, .Net 3.5
I have two tables - Reports, Usage
Report table:
RId
RName
RGroup
Usage table:
UId
UUser
What I want to do is make a page that will list all the reports in the Reports table and have a checkbox next to each name. A user can check each report they use and when they click "submit" it will insert each ReportID into the Usage table.I'm guessing that I should use a GridView to display all the Reports?How would I make it so that the "submit" button would insert each "checked" record into the Usage table?

If I create a data tabe in C# like so:
datatable t = new DataTable;
DataColum C1 = new DataColum;//ID column
t.Columns.Add(C1);
//the same with column C2
Then I fill up the table with some data. Then the goal is to either insert this data or update data in an SQLtable in SQL. If the data is inserted, the ID column in t would be empty, if updated, it would not be. So in the insertion case, the sql query needs to make sure that unique IDs are assigned during insertion, in the update case, it just has to look for the right IDs.How to go about this? Asking because I am only familiar with updating and inserting single lines into a table. One could loop in C# over the datatable t of course and insert or update line by line, but this would probably be slow. Is there a way to write an SQL query like this somehow:
Insert Into SQLTable Values (@t)
?
And Update like this:
Update SQLTable SET ... Where C1 = @t.C1
Or something like that.
I know that SQL server can create automatic update and insert queries and that you can then type things in C# like
Adapter.Update(t);
But, this has proven to be super slow on our server, for unknown reasons. I have asked on this forum and got some answers from experts, but was not able to srot out the problem. How can we write a custom SQL query that allow updating and inserting a whole table, instead of just one line at a time?

In general, If multiple users thru an application try to update the same tables in database simultaneously, then by default on what basis the priority will be given.Like if we don't have any extra logic for the locking implemented.

The topic of sql server deadlock has been discussed many times, however, I was unsure that even two simultaneous inserts on a table can end up in a deadlock situation. Scenario: While testing our application (SQL Server 2005 as backend, ASP.net 3.5) we inserted records into a table simultaneously (simplified overview) and that resulted into a deadlock for more than 70% of users.
I could not get a hang of this as how an insert is being deadlock as this is not a case of multiple resources. After a detailed analysis (of reproducing the bug by two users) I found that both the processes were holding a RangeS-S lock on the primary key index of the table and were trying to convert this into RangeI-N lock, that resulted into a deadlock and one transaction being killed.
Question: Can we avoid or reduce these kind of deadlocks as this is not a case of change in order of access of resources? Cant' we force the transaction to get exclusive lock initially so that it blocks the other process and avoid deadlock? What (adverse) effects that may have? Also could some one explain more about RangeI-N lock.
Isolation Level for this was "Serializable".

I m getting following error in my eventvwr . I couldnt find reasons of the following error.
"Transaction (Process ID 110) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. "
The only thing my page is doing is inserting/updating data into a table in sql and the thing I can think of is because multiple users are using the same page to insert/update data? Will that cause deadlock?
