Hi..
I have a SQL Server 2005 Database .. I develop for the customers a C# Application , that sends some specific Information to my central Database.
If I would create a connection over tcp/IP (in order to send data to central database) like
sqlconnection1.ConnectionString = "Data Source=192.XXX.Y.ZZ,1433;Initial Catalog=Muster;Integrated Security=True";
it would not be reliable. How can we make that safe?
Thanks...
SQL 7.0I have a form in ASP.NET and I want to write the values to the SQLServer tables.The tables are Customer and Address tables.There will be an insert into the Customer table, and I need to use theIdentity of this inserted record for the Foreign Key in the Addresstable insert.For exampleINSERT INTO Customer (CustomerName)VALUES (@CustomerName)Select @@identity as CustomerIDINSERT INTO Address (Address, CustomerID)VALUES (@Address, CustomerID)My question is this. If I put this into a single stored procedure canI absolutely GUARANTEE that the @@identity value will be from theCustomer table insert, or could it feasibly be from another, as itwere, colliding operation?TIAEdward--The reading group's reading group:http://www.bookgroup.org.uk

What I need is to make sure that in case if my Windows CE based device lost power supply my SQL Compact 3.5 database will not be corrupted and I can read data from it.
Has anybody any experience in this area?
This is critical requirement for our project and I want to know it is feasible or not.
I have set up two Maintenance Plans to do daily backups overnight for our two DBs that are on our SQL server.
As a separate strategy we want to have a second backup done nightly that would involve
#1 detach the db(s)
#2 copy the mdf(s) and ldf(s) to L:xxx
#3 attach the db(s) again
#4 zip up the db(s)
#5 copy the files to a different server for storage.
I created #1, and #3 in query analyzer and saved the script.
I want the process to run at say 2AM and don't know how to schedule them to run - that is #1 ... #2 ... #3. Anyone have sample scripts for this kind of a backup strategy?
This seems like a very simple process especially for a restore and especially since there would not be any trasaction logs involved. This way if we had a KRASH we could take the backup from the separate server and install it on a warm SQL backup server.
Apart from the new servers name then what other steps would I need to cover to get the apps up and running in the quickest time. The app software runs as a client install - Access 97DB] I'm especially curious if I need to have more than a fresh MS2000 SQL server install.
I'm know I'm asking a lot for a first timer.
It seems we want to handle disaster recovery BEFORE we even have our first system crash.
many thanks
Maybe I am just a lot better at this than I thought, but I figure that somewhere there is a mathematical rule that is being overlooked. When I run dbcc sqlperf (lrustats) on some of my production machines, I sometimes end up with a cache hit ratio (which is defined as a percentage, mind you) that is slightly over the limit:
Statistic Value
-------------------------------- ------------------------
Cache Hit Ratio 100.00898
Cache Flushes 0.0
Free Page Scan (Avg) 0.0
Free Page Scan (Max) 0.0
Min Free Buffers 331.0
Cache Size 4362.0
Free Buffers 9434.0
I suspect some counter somewhere is getting wrapped around its 4 byte limit. Is there any reliable source for getting statisics about SQL Server performance? Users tend be unreliable and say everything is slow.
I have a process that restores a backup from a primary server to a backup server daily. When doing the restore, sometime it fails (for various reasons).
I have coded a job to Set offline, set online, an then do the restore:
RESTORE DATABASE [xxx] FROM DISK = N'D:Backup Stagingxxx.bak' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10
Sometimes it fails to bring back online, other errors as well. Is there a reliable method of doing this?
Hi,
For this scenario, what is the best method of exporting data to sql 2005.
I want to export data from desktop app across internet to sql which can do on a row by row basis, but this is very slow and if the connection goes down halfway then pretty much buggered.
What is the best, reliable and fastest way to copy data across internet (several thousand rows), I have read about Bulk Insert etc... but also how would get around an upload and crashes half way, is there a way of uploading and until the whole upload goes through then the data is inserted into the database.
Would appreciate any guidance.

I have been tring to get this one line figured out for a few days now.
'Job2 Info
Dim selectSQL2 As StringselectSQL2 = "SELECT * FROM '" & CompanyKey & "'" '<<-------HERE
Dim cmd2 As New SqlCommand(selectSQL2, con)
'Job2 Select
Try
con.Open()
reader = cmd2.ExecuteReader()
(I have the full code below.) So here is the problem, this code is not populating the datagrid. There is data in the table I am selecting from. When I log in, my CompanyKey value displays in the label as "21". When I take out the "CompanyKey" variable, and just type in 21, the grid is populated. It is confusing the heck out of me. I have tried it this way:
selectSQL2 = "SELECT * FROM [" & CompanyKey & "]"
-and this way:
selectSQL2 = "SELECT * FROM & CompanyKey
and all the other ways I could think of. I researched it and can just not get it to work any way I do it. Any suggestions? Full code below:

I posted a more detailed technical question a couple of weeks ago
with Subject = "Compact Edition 2005 Subscribers - Merge Agent failed after detecting that retention-based cleanup has deleted metadata"
But I got no replies.
Now my question is simpler: Is SQL Server 2005 Merge Replication reliable with Compact Edition subscribers on WindowsXP tablets?
We deleted all users' local databases a couple of weeks ago, and republished two publications with retention = 60 days.
Now we have at least one user who can't sync with the server, and replication monitor shows the error below.
But if she e-mails her sdf file to a support person, they can successfully sync her database.
We're sure that it's not a permissions issue, which is a normal suspicion when one user can perform a task that another can not.
It doesn't seem like a retention problem, because she's well inside the retention period.
She can successfully sync with the publication with upload/download tablers, but not with the publication with download only tables. Both publications were created on the same day, by the same DBA, with nearly identical properties.
This problem user has operated in the past with no problem, and she's configured identically to all of the others. It just seems like random flakyness with merge replication for Compact Edition subscribers.
I feel stupid saying that, because it sounds like I believe in a magical ghost in the machine. So my question is - IS MERGE REPLICATION A LITTLE BIT FLAKY FOR COMPACT EDITION SUBSCRIBERS ON XP MACHINES?
We've applied SP2 to the server, but no subsequent HotFixes.
We're trying to sell users and management on developing a larger occasionally connected system with the same replication scheme, so we need to know if it deserves our confidence.
Error messages:
The Merge Agent failed after detecting that retention-based metadata cleanup has deleted metadata at the Publisher for changes not yet sent to the Subscriber. You must reinitialize the subscription (without upload). (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199402)

Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

When using jdbc with IntegratedSecurity, I run into this problem when the machine is not part of a domain & gets its IP address via dhcp. Is this expected behavior or a bug in the jdbc driver.
The SQLServer and client application are installed on the same machine and a local admin is logged in, running the client app.
If I change one of the two parameters mentioned above, the connection can be established leading me to believe this may be intentional for security issues. Am I correct?
When I create a new odbc connection to a SQL server 2005 Db I get a failure telling me dat de SQL server does not allow remote connections.
How can I allow the server to allow this.

Let me set the stage of my testbed configuration: On Windows XP SP2, my default connection to the Internet is via wireless express card modem using EV-DO via Verizon Wireless. Let's call this connection A. I also have a traditional wireless network connection (802.11g) that is always enabled. Let's call this connection B. Connection A is always connected during normal business hours. Connection B is not and is often searching for a wireless network to connect to when nothing is in range.
Yesterday, connection B was continuously trying to connect to a wireless network not under my control, meaning that the connection was never established and notification messages continually popped up to complain of this fact. Over time, I've learned to ignore these messages and go on doing my daily work without much thought of the possible implications.
Then, things started to get odd. I was running our application, WebWatchBot, to perform some simple tests of various websites and servers, when I started to get messages from the application that database connectivity was lost, which is a message that pops up to inform the user that the connection is forcibly dropped by SQL Server. After a few moments, the connection to the database was re-established and the message went away. Since I was actually working with SQL Server, I thought it was an anomoly, so I continued on. Then, it happened again. And again. Then, I noticed that the "database connectivity lost" message started to coincide with the wireless connection's (connection B) inability to connect with a wireless network.
Why would this be happening? The database and application are on the same exact computer. The connection to the database is via ODBC drivers over tcp/ip, but why would connection B affect this?

I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.
MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.
The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.
(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.
Dear 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

I have two machines, the one has Windows 2003 server and the other has Windows Xp Pro on.
The 2003 one has SQL Standard Edition 2000 on where as the XP Pro has MSDE 2000.
I'm trying to run a windows based app from the 2003 server and it connects to a database on the XP Pro PC.
When running the application i keep getting the following exception:
"A Transport-Level error has occured when sending the request to the server (Provider: Named Pipes Provider, error: 0 - The specified network name is no longer available)
After using Preformance monitor on the XP machine it seems that when the app starts and the user logins in it make a SQL connection but then the connection is lost then the exception pops up. then i click continue and try it again then it works, then a couple of secs when using the system it pops up again. The Performance Monitor Test shows that the SQL connection keep being lost. The network is fine. its has something to do with SQL and Named Pipes and stuff.
When running the app on the Xp machine and the Connection is made to the 2003 machine there is no problem.
There are other connection made to the Windows XP Machine but i doubt that it affects the app.
The Windows firewall is off as well.
Please can anyone help.
I'm having trouble receiving a file via FTP. I've done this before, so I'm surprised how much trouble I'm having. I'm getting the error:
[Connection manager "FTP Connection"] Error: An error occurred in the requested FTP operation. Detailed error description: The connection with the server was reset .
I've tried to FTP via Internet Explorer 6, and it works fine. I've tried going into the "FTP Connection" and putting in the password, and clicking "test connection"... works fine again.
Any ideas for me to troubleshoot? I've shut down the package and re-opened it, but to no avail.
I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?
I'm having a strange problem with this but I know (and admit) that the problem is on my PC and nowhere else. My firewall was causing a problem because I was unable to PING the database server, switching this off gets a successful PING immediately. The most useful utility to date is running netstat -an in the command window. This illustrates all the connections that are live and ports that are being listed to. I can establish a connection both by running
telnet sql5.hostinguk.net 1433 and
sqlcmd -S sql5.hostinguk.net -U username -P password
See below:

Both these utilities show as establishing a connection in netstat so I am able to connect the database server every time, this worked throughout yesterday and has continued this morning.
The problem is when I attempt to use SQL Server Management Studio. When I attempt to connect to tcp:sql5.hostinguk.net, 1433 nothing shows in netstat at all. There is an option to encrypt the connection in the connection properties tab in management studio, when I enable this I do get an entry in netstat -an, see below:
TCP 81.105.102.47:1138 217.194.210.169:1433 TIME_WAIT
TCP 81.105.102.47:1139 217.194.210.169:1433 TIME_WAIT
TCP 81.105.102.47:1140 217.194.210.169:1433 TIME_WAIT
Amost as if it's trying the different ports but you get this time_wait thing. The error message is more meaningful and hopefull because I get:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (.Net SqlClient Data Provider)
I would expect this as the DNS has not been advised to encrypt the conection.
This is much better than the : Login failed for user 'COX10289'. (.Net SqlClient Data Provider) that I get, irrespective of whether I enter a password or not.
This is on a XP machine trying to connect to the remote webhosting company via the internet.
I can ping the server
I have enabled shared memory and tcp/ip in protocols, named pipes and via are disabled
I do not have any aliases set up
No I do not force encryption
I wonder if you have any further suggestions to this problem?
I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
Thanks,

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"...
The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.
Can I connect from a SQL Server 2005 database to a SQL Server 2000 database, without establishing a linked server connection.
I need to fire a SELECT query on a SQL Server 2000 database, but don't want to add it as a linked server. Is there any way I can do this or its not possible??
I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.

I use Microsoft Windows Vista Home Professional
I have already installed to my computer Microsoft SQL Server 2005 and SQL Serves Express. I used to be successful to connect to the SQL Server but now I CAN NOT.
Not: I try to run SQL Server 2005 but I can not, even I logged on to my computer with an administrator rights. On the other hand I can start and stop the SQL Server Express easily.
As a result, how can I solve this problem.
Thanks in advance.
