Is there a way that SQL can automatically look at each users'
connection and make sure it is still connected through the third party
application? The problem is that when a connection to this application
is not terminated properly, the SQL server is not notified of the
disconnect and the user cannot log back into the application until all
the processes are completed and the original session terminated.
Thank you.
Hi,
I have recently started using SQL Server with a 3rd party application and have come across a problem and i have no idea how to fix it...
The database has a column of numbers that go up either by 10 or 100 depending on the letter in another column. eg:
100 M
110 P
120 P
200 M
300 M
400 M
500 M
510 P
520 P
The 3rd party application has just been updated and now can add new rows to this table. The only problem is that the added row needs a new number, and the rows below need to be recalculated.
Is there anyway this can be done? Any help or suggestions would be great!
Cheers,
BL
Hello.
I would like to analyze how a particular 3rd party business application interacts with SQL server.
Specifically, I want to capture the "exact" SQL commands (transact-sql statements) that this application issues whenever it completes an operation for the user of this application.
In other words, suppose the application issues the SQL command "INSERT INTO table (a,b,c) values (1,2,3)" to add a new entry to the database. Then, my understanding is that if I instead issue the exact same command with a tool like "SQL query analyzer", the database will be updated in the exact same manner. Hence, I have effectively accomplished the same job that the 3rd party application does without even using it (by idependantly issuing the same command to the database it uses).
Is this possible? Can I obtain all the information I need just by running SQL Profiler?
Our current concern deals with stored procedures from a third-party application that were modified in order to correct future data inconsistency that was being generated. Since the stored procedures were not encrypted, I was able to modify them and correct the problem. At the same time, we developed a small in-house application to correct the current data inconsistency and we created new stored procedures in the same database. Now I'm concern about if I had the right to modify those stored procedures and additionally, created new ones inside this database? Am I restricted somehow to use our full version of MS SQL Server with a scenario like this?

View 3 Replies View RelatedDear members,I'am thinking about the "best" way to connect to my sql-server viaADO.Net (if there is a best way).My application uses the sql-server very intensively. At the momentevery database-operation opens a connection, executes and then closesthe connection.Another way would be to use only a single connection to the database,which is opened when the application starts.What do you think is the better way to get a high performing sqlserver: using one single application connection vs. using oneconnection for every operation?Cheers, Sebastian

View 4 Replies View RelatedOK, so I'm working on a project that requires the dynamic generation of SQL statements. Now in Visual Studio .NET I'm sure many of you have used that wonderful visual database tool that allows you to magically "verify sql syntax" at the click of a button. It takes a query that looks like this:
"SELECT A.AFFID, A.UserName, A.Pass, A.FirstName, A.LastName, A.Company, A.Street, A.City, A.State, A.ZIP, A.Country, A.phone, P.EMail, A.RecieveEMail, A.SSN, A.JoinDate, A.AffType, P.ProductId, P.BuyerId FROM Affiliates A, Purchases P WHERE (ProductId > 0) ORDER BY 1"
and transforms it into something that looks like this:
"SELECT A.AFFID, A.UserName, A.Pass, A.FirstName, A.LastName, A.Company, A.Street, A.City, A.State, A.ZIP, A.Country, A.phone, P.Email, A.RecieveEMail, A.SSN, A.JoinDate, A.AffType, P.ProductID, P.BuyerID
FROM Affiliates A CROSS JOIN Purchases P
WHERE (P.ProductID > 0)
ORDER BY A.AFFID"
My question is: is there anything in the .NET platform that would allow me to achieve the same kind of result programatically (i.e. transform standard sql to tsql syntax and verify the syntax of the query at run time)?
Any help would be appreciated! Cheers.
To: All,
Hi, well thanks for reading this thread. Anyway I got a problem where i can't accurately verify whether a user had successfully login to my application.
I got a database to store the user name and password. So whenever a user login, i would use a while loop to read all the user name and password, and an if statement to verify whether the user's name and password matches to the ones stored in the database. This method doesn't work when there are multiple records in my database, because the if statement would compare the user given name and password with all the user name and password in the database. Hence resulting a mismatch.
Well I really hope that you understand what my problem is, really need help with this problem as I'm really clueless. Can somebody please help me, please teach me how to rectify this problem?
Well i think the core problem would be to compare the user name and password with the records in the database one at a time, and once it is found, stop comparing and allow user to enter site.
Yup I think that's all, sorry for the lengthy thread. Anyway thanks a million and have a nice day.

How do I tell what SQL licensing option (processor, device CALS or user CALS) was taken when the server was installed? I have taken over a SQL 2005 server and I would like to check how many CALS (if any) it is licensed for.
View 2 Replies View RelatedHey anyone,
I got a problem to check a connection whether it is established or not from my C# Application to SQL Server.
I am developing my application which can run in 2 modes:
1. Online: There must be a connection to SQL Server to get new data updates.
2. Offline: I dont need a connection to SQL Server. I set a timer to tick every 5 seconds and it will check the connection with SQL Server and my problem here: (this is my code)1 public static bool checkConnection()
2 {
3 SqlConnection conn = new SqlConnection("mydatasource");
4 try
5 {
6 conn.Open();
7 return true;
8 }
9 catch (Exception ex) { return false; }
10 }
Yes, it works but my application seems to wait about >3 seconds to get the return "False"; I tried to add "Connect TimeOut=1" in my Connection String, but the problem is still there.
I dont know whether there is a faster way to check the connection to SQL server which is established or not.
Thank you very much,

Hi there,
Has anyone ever encountered problems making .Net applications connect to a SQL database on SQL 2000 with SP3a?
It's running on a virtual machine with a Windows Server 2000 Std with SP4, the .Net application is working with .Net Framework 1.1.4322.573. For some reason it can't connect to the SQL database using the specified username and password in the web.config file even though the user exists in the SQL database. I've tried using the SA password but this still doesn't work. I can logon to SQL Query Analyzer using the SA password but not using the other username.
The .Net application does work on other systems of mine all of which can run on Windows Server 2000 and 2003, I have compared them but can't find any differences.
Any ideas anybody?
Thanks,
Chris

I was wondering if someone could help me answer this question.
If I had a site like Yahoo, that constantly had users accessing it. Would it be a good or bad idea to automatically open a database connection to SQL Server on Application Start? What would you recommend? Would opening and closing the DB connection on every page save alot of overhead and bottleneck? Thank You.
Hi,
I'm testing the use of application roles for security. The customer I work for has still a lot of ASP intranet applications running. We're migrating the databases to a SQL Server 2005 server.
I've changed the connection string to a user without any permissions but to log on. After that I use an application role for permission to select different tables and to execute Stored Procedures.
The first queries do execute but after that I get "Permission denied", like I haven't got the application role anymore.
Any ideas?

I have VB6 application on several desktops connected to SERVER A (SQL Server 2005) in TESTING. I know I can change some registry values in VB6 application to connect it to SERVER B(SQL Server 20050 in PRODUCTION.
but it is work on each and every desktop.
Is there any way to do something on SQL Server 2005 Engine end (like Alias) so I don't have to make changes for SERVER Redirection in each and every Desktop machine(client), and Just I make change on SERVER Side.
any help or idea on that?
Thanks,

2.I have developed a VB.NET EXE file -In that application(inside the code) i am using run time connection string queries to connect to the sql server database & created run time tables.
Suppose if i want to install the application to all clients/users how to Configure that application - self configuration/self installer to the installing machine SQL SERVER.
How can i do this ?
3.Is there any way i can write config file for sql server along with exe application code ? How can i do this ?

I have a VB6 application that has MSDE as its current backend. In
testing moving to SLSQLExpress I've noticed, since this application is run on laptops, that if I disconnect the network cable while I'm in the VB6 app I lose "connection" to the database. If I end task on the app and restart it it works fine. If I reconnect the network cable while the app is running and then disconnect it the app runs fine. Also this happens when I'm connected to a wireless network and then disconnect and disable that connection.
In my template.ini file I have DISABLENETWORKPROTOCOLS=0. Is there a setting I'm missing? I can't seem to find anything else to set in the ini file.
I am trying to use msde for the startup kits. but i cannot connect to it. How can I do a simple test to verify it is installed and that I can log into the db?

Hey everyone, I'm new to .NET and I've recently inheirited a rather large and busy asp.net website. I was asked to add a testimonials section on each page that will randomly pull a testimonial out of the db. This is fine, however, I'm getting random errors about the DB connection either being closed or connecting. Here is the code for the testimonials class: 1 public SqlDataReader GetTestimonials(ref SqlDataReader reader, int iCatID, string sLanguageType)2 {3 SqlCommand cmd = new SqlCommand("sp_DVX_Testimonials_Fetch", Connection);4 cmd.CommandType = CommandType.StoredProcedure;5
6 cmd.Parameters.Add(new SqlParameter("@Cat_ID", iCatID));7 cmd.Parameters.Add(new SqlParameter("@LanguageType", sLanguageType));8
9 reader = cmd.ExecuteReader();10
11 return reader;12 } I know this isn't the best way to do this (especially for each page[this site averages about 1000 hits a day]), so I was wondering was--is there a way to maintain a single DB connection that's set up in the Application_Start that will maintain the connection so I don't have to worry about this error. If not, does anyone and any ideas as to what would help? Thanks in advance!

We have always used sql servwer login to the servers for all our applications for out intranet apps
And we use windows auth to do development
So when we do that we logon to wuindows, and then just connect, with no password required
But how does an application "logon" to connect to a database
Is it just in the connection string just like sql server auth
or is it different?

Hi all,
I think I can do this, just want to check
Can I have an sql server database (mdf file) on a server and allow windows applications at different site manipulate the database.
As far as I am concerned the only thing that needs to be configued is the connection string..is this correct.
[i would rather use windows applications rather than asp pages]
If I can, the best way to manipulate the database is to use stored procedures. How would I do the following to create and execute the following proposed procedure:
Insert data into a table
Update another table as a result
Execute the store procedure on a form to execute these two statements
Thanks in advance

Hello All,
I'm trying to develop a stored procedure that would do one of TWO things:
1. Return a 'status' that a value does not exist, if I were to provide the parameter via an ASP.NET2.0 page
2. If it does exists, to return the row data associated with that value (id number)
The stored procedure would search a SQL Server table within it self first. It that fails it would look at an Oracle table (work order table). And if that fails to return a 'row' to look through another Oracle table (work request table). If that doesn't occur, then it would throw the result as described in #2.
If the result exists in one of the TWO Oracle tables it would then insert that row into the first SQL Server table that the stored procedure searched through AND would return the row set to the ASP.NET page.
While all this is happening, I was hoping to get some insight as to how to create a "Please Wait..." feedback and then moving to the final result.
Looking forward to the wise words of the many on this forum, as I have experienced in the past! :)
