Hi, I am building a web application now that will be used by multiple users. Users import data from a CSV into table 'temp' which is later converted to the right data type and then moved to another table, but I was wondering what would happen if more than 1 user was importing different files at the same time.
Will this create a problem, if so how can I fix this?
Thanks for the help.
We have an application where users log in and set up a ConnectionString based on the login-info. As to now, we have used
Application.Contents("conn") = (strConnectionString)
in Global.asax.vb (Application_Start section) and then in the in the webforms we use
Dim con As New SqlClient.SqlConnection
con = New SqlClient.SqlConnection(Application("conn"))
con.Open()
......
......
con.close()
(Each user has their own sql database that they connect to using the same scripts.)
The question is: When many users are logged on at the same time, will the use of Application.Contents be a safe way to connect to each users own database or is there a possibility that users suddenly will try to establish a connection to a database that is not their own?
Scenario: User1 logs in at 10:00 and establish a connection to his own database. At 10:05 User2 logs on and establish a connection to his database since Global.asax.vb is run again. Will User1 now use User2's connection so that he is actually woking on User2's database?
Is there a better/safer way to do this connection in Global.asax.vb ?
Help much appreciated!!!!
I'm developing an application in ASP.Net that uses SQLServer. The database person in the team wants to have each user have a seperate login to the database so he can tell who has done what changes in the database. Is this a good practice? Or are their performancesecurity issues with this model?
View 3 Replies View RelatedWe have an OLTP application with multiple one to many tables relationships that are edited client side. For Example the primary table has descriptive components. One of the multiple table have things like parts and quantity ordered linked by a record number back to the primary table.
When our client transmits their transaction, they actally running a batch job which sends all the client side tables to the SQL Server and then we are trying to issue a stored procedure server side to push this data into our 'dbo' owned server side master tables.
Our problem is generating the fully qualified table name for the from clause.
We have tried declaring a variable but the stored procedure won't compile. Tried user, user_name().
Any solutions would be greatly appreciated.
We are trying to setup security on our Sql Server. We are using Integrated
Security.
The problem we are having is that we need to have a user belong to multiple groups within one database. The user would have different rights depending upon which group they belonged to.
So far we have not found anyway to accomplish this setup.
I would appreciate any ideas/thoughts on this matter.
Thanks,

I don't know whether this question belong here, but....
In the past I had many customers using the same website each with their own domain name and their own database. To accomplish that, I used MS Access and placed each customers database in separate directories. I steered the customer to the correct directory using their domain name. I am now trying to accomplish the same thing using aspnetdb.mdf and other .mdf database files. I am using the aspnetdb.mdf database for membership, etc. I want the aspnetdb.mdf database file to be unique for each customer. Does anyone know how to accomplish what I was doing with MS Access using aspnetdb.mdf? Is there any way to have multiple web.config files each of which would be dedicated to a particular customer?
Dear all
In our organization there is a call center where operators entry call details and custormer qruery in a table using front end application. For these queries there are multiple no of executive who will reply the query using a front end application. using the application the exectives retrive specific no of records from call center table(if there are unreplied call exists) and reply them. When a excutive retrives specfic no of rows, i want to update a flag in that rows, so that others do not get them.
I use the following procedure which is creating dead lock when multiple users execute it simultaneously

We are currently using Crystal reports but are considering using SQL RS. We need to know if there is a restriction on simultanoeus access to the same report by multiple users? What happens when multiple users try to access the same report simultaneously? If reports can be accessed simultaneously, do the requests queue up or are they processed concurrently?
Any help on this issue is greatly appreciated.
Hi, i just need some help?? just some info?is it TRUE that SQL Server 2005 Express Edition (free) is capable ONLY of SINGLE user?i mean if i have a data driven page, if someone is using or editing the data in my page, does no one can access my data base simultaneously??i hope you could enlighten my mind, thanks
View 2 Replies View Relatedbasically, is it inefficient to open and close a data connection everytime data needs to be retrieved or is there a way for a user to use the same conenction over multiple pages orfor multiple users to share one global data connection I just wanted to know this before I built a site where data could be constantly being pulled or put into the database.It would be easier to just keep opening and closing the connection since it just means pasting in the small chunk of code I use to do that where I need it. I hear speak of connections sometimes not closing etc and wonder if that is an issue then if you are opening and closing too many of them. I am using SqlConnection SqlCommand and SqlDatareader , my code works, just wondering if my approach lacked scalability before I find out too late and have to rewrite everything . Jim

My developers would like a 'sandbox' database with full ddl and dml permissions, however, they do not want others to read/change/drop their objects. With SQL 2005, can DDL permissions be granted to a user at the schema level? I'd rather not set up a database for each developer.

Hi Everybody,
I am trying to setup a stored procedure that runs through a Reminders table and sends an email to users based on DateSent field being smaller than todays date. I have already setup the stored procedure to send the email, just having trouble looping through the recordset.
Code Snippet
CREATE PROCEDURE [dbo].[hrDB_SendEmail]
AS
BEGIN
DECLARE @FirstName nvarchar(256),
@LastName nvarchar(256),
@To nvarchar(256),
@ToMgr nvarchar(256),
@Subject nvarchar(256),
@Msg nvarchar(256),
@DateToSend datetime,
@Sent nvarchar(256),
@ReminderID int,
@RowCount int,
@Today datetime,
@Result nvarchar(256)
-- Get the reminders to send
SELECT
@ReminderID = r.intReminderID,
@DateToSend = r.datDateToSend,
@FirstName = e.txtFirstName,
@LastName = e.txtLastName,
@To = e.txtEmail,
@Subject = t.txtReminderSubject,
@Sent = r.txtSent
FROM
(auto_reminders r INNER JOIN employee e ON r.intEmployeeID = e.intEmployeeID) INNER JOIN ref_reminders t ON r.intReminderType = t.intReminderTempID
WHERE
(((r.datDateToSend)<20/12/09) AND
((r.txtSent)='False'))
-- Send the Emails
WHILE(LEN(@To) > 0)
BEGIN
EXEC @Result = sp_send_cdosysmail @To, @ToMgr, @Subject, @Msg
END
-- Mark the records as sent
IF @Result = 'sp_OAGetErrorInfo'
BEGIN
SELECT @Sent = 'Error'
END
ELSE
BEGIN
SELECT @Sent = 'True'
END
UPDATE auto_reminders
SET
auto_reminders.txtSent = @Sent, auto_reminders.datDateSent = @Today
WHERE
intReminderID = @ReminderID
END
GO
From the code you can probably tell I am new to writing stored procedures, so I apologise for any obvious errors. My major problems are :-
how to loop through each record
how to get todays date
whether the struture of the procedure is correct
Also, if you think there is an easier way or a better method, please suggest it. I am open to any suggestions you may have,
Thanks in advance

We have an existing SSRS server, and have just created a new child domain. We'll be migrating users from the parent to the child, and want to add the users of that new domain with access to SSRS. In the parent domain they are able to access, but after migration with the child domain account, they cannot.
I have added the group CHILDDomain Users with a system user role on SSRS, and PARENTDomain Users was already there.
Is there any additional step I should/could take to get this active?

I am trying to create a report using Reporting Services.
My problem right now is that the way the table is constructed, I am trying to pull 3 seperate values i.e. One is the number of Hours, One is the type of work, and the 3rd is the Grade, out of one column and place them in 3 seperate columns in the report.
I can currently get one value but how to get the information I need to be able to use in my reports.
So far what I've been working with SQL Reporting Services 2005 I love it and have made several reports, but this one has got me stumped.
Any help would be appreciated.
Thanks.
I might not have made my problem quite clear enough. My table has one column labeled value. The value in that table is linked through an ID field to another table where the ID's are broken down to one ID =Number of Hours, One ID = Grade and One ID= type of work.
What I'm trying to do is when using these ID's and seperate the value related to those ID's into 3 seperate columns in a query for using in Reporting Services to create the report
As you can see, I'm attempting to change the name of the same column 3 times to reflect the correct information and then link them all to the person, where one person might have several entries in the other fields.
As you can see I can change the names individually in queries and pull the information seperately, it's when roll them altogether is where I'm running into my problem
Thanks for the suggestions that were made, I apoligize for not making the problem clearer.
Here is a copy of what I'm attempting to accomplish. I didn't have it with me last night when posting.

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.
I am in the process of creating a Report, and in this, i need ONLY the row groups (Parents and Child).I have a Parent group field called "Dept", and its corresponding field is MacID.I cannot create a child group or Column group (because that's not what i want).I am then inserting rows below MacID, and then i toggle the other rows to MacID and MacID to Dept.
