Sql Data Sharing
Sep 17, 2004
Hey guys,
I have a quick question about SQL 2000 server data sharing.
I am currently using SQL 2000 Server Enterprise and I need to do synchronous data sharing with flat files. I have an ODBC connection to the files. I was able to easily share this data by using linking in Microsoft Access, however, for the life of me I cannot figure out how to do the same in SQL. We are in the process of converting legacy code. The old code will of course be communicating with the flat files and the new code will be talking to SQL server. So it is vital that the 2 access methods are both pulling the same data. Does anyone have any ideas???
Help would be greatly appreciated
Thanks

Hi:I'm trying to setup a MS Cluster but I don't know if it is feasible toconfigure it in the way I think.I have two machines with win2k server and MSSQL-2000 one of them iscurrently performing as the production database and the other one isthe backup. The secondary one is keeping updated via the "LogShipping" technic.We almost covered all the other possible failures of the othercomponents (ie: network, power, application servers, etc), the data ismaintaned in a raid which is ok but we want to cover also thepossibility of that failure too (yes, you can call us paranoids!! ).The thing is we want to create a cluster that do not share the data,but each machine of the cluster have thei own set of the same data.My intention is to configure the cluster to detect a failure of onemachine and initiate the failover to the remaing one using theappropiate scripts related to the promotion of a secondary serverkeeped updateusing "log shipping".Have anyone some experience with that kind of solution ??Thanks in advanceLeonardo

We receive data files from different external customers, and these files have identical layouts.
I'm planning to set up a package for each customer. Each package will contain a flat file source -> OLEDB transformation dataflow, (followed by other customer-specific data flows).
What I'd like to do is just create this dataflow once, parameterising the flat file and table names. Is it possible to include this dataflow in each customer package so that if the flat file layout changes, I can just modify the connection managers in the one place, and then recompile each package to pick up the changes?
Any advice appreciated.

I am in the process of designing a web application for our application that will be available to the general public.Basically will be used to collect information for a case report. I need to know if there is a way from our internal database driven application to push certain data up to the website that the database may be behind a firewall so I cannot make a direct connection to the external database. I thought I heard about some sort of data sharing protocol. I then will be storing the users entered data in the website database and pulling it from the internal application. So basically I need a secure way of sending and receiving data between a server/client app on a LAN system to the Web site database that could be hosted outside the LAN.
I hope this made sense.

Can you use SQL Express remotely instead of locally.
I have been told that I might be able to use SQL Express as my network server for sharing files. Is this possible, or do I need a different version of SQL to do this?
I have been reading the VBE forums and from what I gathered was that SQL Express is only for a local table only, is this true?
If not, what is the work around, and how do I go to another pc to find out if it is sharable?
I would hate to get several months in my app design and learn that I was headed in the wrong direction.
Thanks

How can I share stored procedures so I can call them form different databases ?
Basically, all databases have identical table names and structure but containing different data and I don't want to replicate all stored procedures on every database. There are too many and will also be very unpractical to maintain the code.
Thanks,
Moshe

Hi :)
I would like to know if it is possible to link two databases together
(in my case ASPNETDB, and another mdf database) so that I can run
queries on those shared tables. For example, I would like to use the
uniqueidentifiers from the ASPNETDB tables in my own tables.
Thank you!
(I do use the latest version of Visual Web Developer).

I am writing a DB-driven application, using Visual Studio. I have a database that i want to be able to move from one computer to another, and still be able to access it. It's probably something simple, but I must be missing out something.
The problem is that if i choose windows authentication, then the DB cannot be used on another computer. I also had no luck when using SQL Authentication.
How can this be done? What form of authentication should be used and how, so that I can just copy my DB from one computer to another, then log into the DB using a username and password?
*Any* help would be greatly appreciated!

Hi guys,I've got two apps that are going to have pretty much the same users and i wanted them to have the same ASPNET.MDF user database. Is it possible to store the ASPNET.MDF in a different location and then have the two apps access it from there or alternatively have it in the App_Data folder of one of the apps and then have the second app access it from there?Thanx

Hi;
I have an ASP.NET application with a SQL Express database.Here is the connection string used on the web application:"Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|admindata.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"
Now, i create a Windows application which will run on the server to perform some scheduled tasks, for the Windows application I used this connection string:"Data Source=.SQLEXPRESS;AttachDbFilename=D:WebSitesmywebsite.comwwwApp_Dataadmindata.mdf;Integrated Security=True;User Instance=True"The problem is, when the web site is running and using the database, the windows application can't connect to the database and i don't know where i'm doing wrong, if it's the web application connection string or, if it's the windows application connection string.
I hope someone had the same experience and can point me to a direction.
Thank you;Emerson Brito

Does 7.0 allow multiple databases to share a data file/log file?
Will a large data device file shared by 10-25 databases present any problems?

Would someone please tell my how to share the same NT Login on a Publisher and a Subscriber Server. For example, one of
the requirements for Replication is that the Publication Server and
Subscription Servers should share the same SQL Executive account. I tried
doing this in Control Panel, Services Applet, Startup, and This Account Box. The Subscribing Server is not allowing me to map the login of the Publishing Server. I also tried within NT User Manager for Domains. I am not able to figure this out. I am trying to get Replication to work within a Workgroup on two NT 4.0 Servers SP3, with SQL Server 6.5 SP5a.
Thanks, Kevin

Hello -- Please excuse my extreme newbieness -- trying to get up to speed fast on SQL Server Express for work. I've been able to set up the software, create a database, and access it with no problems on my local computer, but I need to make the database available to other computers in my workgroup. I followed instructions -- enabled TCP/IP and Named Pipes and turned on SQL Server Browser, and I was actually able to manipulate one system database (the "master" database) from another computer but not any other databases, not even the other system databases. I can connect to any of the databases with the SQLCMD commands, but if I try to do any SELECT commands (other than in "master") I get an error: "SELECT permission denied on object '[MyTable]', database '[MyDatabase]', schema 'dbo'". I was only able to get into "master" after adding "guest" as a user, but adding this user to the other databases has no effect. One interesting thing: When I used the sp_table_privileges command on each database, all but "master" showed all privileges being granted to and from "dbo", but "master" didn't show anything being granted to or from anybody. Does anyone know what could be going on here? Am I missing something obvious? Thanks for any and all help!

I'm looking for some advice on how to manage reports that use the same query in their datasets. I have multiple reports that use several datasets that are the same. If I need to make a change to one dataset, I need to remember to update the other datasets. Of course I don't always remember to do that!
Is there a way to create a dataset in a single location and then share it? I was thinking of using a View but I don't think it'll accept the parameters.
I've been cutting & pasting the entire query as I make change but I'm afraid it'll mess that up or forget to update a dataset.
How do you do it?
Any suggestions you have would be helpful.

I have read a number of threads in this forum concerning SSIS packages and Protection Level. I regret to say that I did not manage to find one that covers the problem I am experiencing.
I have saved a package that contains a SQL Server Authentication login and password. In Properties for the Package I have set
ProtectionLevel = EncryptSensitiveWithPassword
I then save my Package and use F5 to run it in Visual Studio 2005 Team Edition. It runs just fine.
I then walk over to a co-worker's desk, have him "Get Latest Version" in Source Control Explorer, and then have him double-click on the SSIS Package. It indicates that he must enter the password, which we do, and then it begins validation of the package. By changing to EncryptSensitiveWithPassword (instead of EncryptSensitiveWithUserKey) many of the earlier error messages went away.
We still get one fatal error, though, which prevents him from pressing F5 to run the package on his PC. The error message is one reported in some other threads in this forum:
Error loading PackageName(C2097).dtsx: Failed to decrypt protected XML node "DTSassword" with error 0x8009000B "Key not valid for use in specified state.". You may not be authorized to access this information. This error occurs when there is a cryptographic error. Verify that the correct key is available.
Naturally we are running this on a computer different from the one on which the package was created/last-saved, and running with a different Windows user.
The package is a fairly simple one: it merely copies a few dozen tables from Access to SQL Server 2005 on a central server.
Might the error message be related to the Access connection? (He has the same rights to the Access database that I do, but those are based on Windows Authentication -- which makes me wonder if that might be the problem. The Access database is located on a central server, and the access rights are controlled through User Groups in the Windows File System.)
I would like for others to be able to run this and other SSIS packages I have developed.
Ultimately we would like to store completed SSIS packages in the File System (rather than in SQL Server 2005), and allow anyone in our team, who knows the password(s) for the packages, to run them without difficulty.
Is this possible?

Ok, I understand it is possible, but I still can't quite get the mechanics of it to work.
I create a new BIDS project, and add a package to it, and add 3
connection managers, and set the server, instance, DB, etc. for SQL
connections. I change the name of each connection manager so the server
name is not there, but use something more like a generic name of what
the database is. Fine. I right click in the Control Flow area and go to
configurations. I enable configurations, and save to a common place on
the C drive. Save everything, exit, VS, fine, and I export all
connection managers properties.
Then I start Visual Studio again. Create another new BIDS project, add
a package to it, and add 3 connection managers. I don't actually
connect them, but use those same generic names from the first
iteration. I enable configurations for the package. I am somewhat
expecting to see the connections change from the same-o-default to the
data I used in the first go around.
I am obviously missing something big here.

Hello,
We have a couple of databases set up, and we replicate data from certain tables between the two database. One of the tables we replicate is the Users table, in which we'd like to encrypt user passwords. Initially I created a certificate on both servers, and found that I could not DecryptByCert a password that was encrypted on the other server, and vice versa. It looks like all I was forgetting to do with supply a 'ENCRYPTION BY PASSWORD = ' parameter to CREATE CERTIFICATE. So, now I have the following:
CREATE CERTIFICATE Cert_UserPassword
ENCRYPTION BY PASSWORD = 'pGFD4bb925DGvbd2439587y'
WITH SUBJECT ='TestingCertificate'
I ran that query on both of our servers, and I find I am able to decrypt the password on both servers. So, as far as I can tell, this is exactly the way I want it to work.
So, now for the question: Is this the right way to go about it? In order to decrypt the password on either server, it means I need to pass the 'pGFD4bb925DGvbd2439587y' password to the DecryptByCert command, which doesn't seem very secure. But if I don't use the 'ENCRYPTION BY PASSWORD', then the cert will be signed by the Master key, which is different on both servers, which will result in a certificate that can't decrypt what was encrypted on the other server.
Is there a way to take the actual certificate on one server, and export it to the other server, so that they're both using the exact same certificate to encrypt and decrypt? I would like to not have the password included in the Decryption command, if I can help it.
Thanks.

Hello,
I'm using an XML file to configure my dataBase connection string. I try to deploy my package on a new server and it works perfectly.
Then I made a second package which also need a configuration for the dataBase connection string. (I made the connection with the connection manager inside packages). The configuration is the same that for my first package, so I thought to use the same configuration file.
I can use the same configuration file but the problem is when I try to generate a deployment for my solution. I got an error which tell me that the xxx.dtsConfig file already exist and can not be copy again.
When I made the configuration in the second package I said that I want to reuse the file ... and I thought that for the deployment SSIS would know that it has to include that file only once ...
Did somebody already have this problem ?
Thanks !

The scenario is an ETL that takes flat file feeds via FTP to move data into varous production SQL server databases nightly.
There are a number of packages involved, and this depends upon the type of data being sent.
There are a set number of servers and databases to receive the
transformed data. I would like to be able to define say 3 servers, and
maybe a couple of databases in each one time in the configuration. For
simplicity lets say 6 databases total. I would like a single point of
maintenance for these 6 locations. I would like all connection managers
in all packages in all solutions to share these 6 settings in all
connection managers. Is this possible? From my initial attempts, it
would appear each package gets its own independent list of connection
managers and which must be configured separately. I don't see how to
share settings, which is really where the power of SSIS configurations
would be.
Similarly, I would like to be able to locate flat files at given paths.
The package may know the name of the file it is looking for, or the
file it will create, and the folder path needs to be computed from a
configured folder root, and for the package connection manager to store
only the name of the file, which never changes.
I can not see how to set something like this up with connection
managers and configurations. Perhaps I still need a highly customized
solution to achieve this, as we did for DTS, where we would only
execute packages using our own executor, which would load the package,
search out all environment specific settings and modify them on the fly
prior to executing the package.
Thanks for any direction you can give here. The books I've read seem to
imply I might be able to do what I need here, but I can't seem to find
the mechanics of making it happen.

Hi
I’m looking for an efficient way of using a singe set of stored procedures to access a number of different databases (Sql Server).
The most feasible option I’ve come up with so far is to send the specific database name through as a parameter. Unfortunately the function “use” isn’t available to stored procs, so it seems I must move the query into a varchar, to then exec it.
There’s been another suggestion of using a web service to store the procedures, but I imagine that this would be very slow and cumbersome.
There must be a better way – any ideas?
Thanks,
indra

I work in a medical facility and and client confidentiality prevents loading my pivot tables to sharepoint at this time.
I am creating several reports that combine data from SQL Server, Cerner medical report DB and some lookup tables in Excel.
Everything works great on my desktop but I'm having trouble sharing my work.
Our normal routine is to drop a copy of our excel files in a Pass through file on the server that has strict access controls.
I think my main problem is my supervisor doesn't have powerpivot on his machine. that will be corrected tomorrow.
My question is: When close your powerpivot workbook, do all the connections go with it. Â If I just drop myproject.xlsx into the pass through will all the links to the varying data sources still be available?

To date I have found no way of defining styles that can be shared either between objects or between reports.
I am looking for the concept of the rdl making a reference to an external css (or equivalent) file. This would allow for me to define a font or image external to the rdl and shared among all my reports. Currently if I want to change my header image, I need to edit 50 rdl files across the reporting suite.
What work arounds are available for this? Is this a coming feature enhancement? If so when? Does the reporting team publish a list of future enhancments?
I know crystal and few other reporting packages have the concept of css or style external to the report.

Hello,
I was hoping that someone may be able to help me with an issue that I am having while trying to deploy my projects using MSI. Here is what I am trying to do.
I have two programs that are using MS SQL CE to share information. The first program is a windows service. The second program is a windows application that I am using mainly as a UI for the service. Each program has a seperate MSI setup program. I am using windows vista and VS 2005 on my developement machine.
The issue that I am having is when I deploy the programs. The windows service is working fine. It reads and writes to the database as expected. I know this because when I debug the UI program through VS 2005, I can read and write from the common SQL CE database with no issues. I am also pretty confident in the MSI program for the UI program because if I install the UI program on the developement computer and run the UI program as administrator it runs fine.
The issue arises when I simply open the UI program or when I try to run the UI program on a windows xp sp2 machine. I am no longer able to access the database file. I have tried many diffent things, but so far with no luck. Most of the attempts to fix this so far have been concerning the location of the database file these have had little or no effect. Again if I open the UI program using the right click option of 'Run as Administrator' in windows vista, the problem disappears.
Thanks in advance for any help. Even a push in the right direction would be helpful at this point. I will keep working on this issue, if I find a solution myself I will repost it here.

Hi
I'm developing a scientific appliation - to forecast the spread of disease. The algorithm has been designed such that different subpopulations reside on separate computers.
The model uses the same set of data repeatedly, and only returns a small signature that reflects the appropriateness of a particular set of parameters.
The model does however change, and I'm looking for a way to roll out this model (which only contains T-SQL, CLR assemblies and service broker code).
I have considered setting up a database on each computer which has the 'data' files which are static, and a separate database which contains the algorithm which can be amended.
Could one then detach the algorithm database making the new version that can then be rolled out (by attaching it to each computer used)?
Is this the best practice? Does anyone have a suggestion as to how to do this?
Go well

It is pretty easy to create the package configuration to the shared, never-changing path to XML file. But to get this to work, I have to add a bunch of package variables which are driven from the configuration. I then use expressions to compute actual paths to source files and packages.
This business of copying a block of variables from one package to another is extremely tedious, and at least to me, something of a maintenance issue. I have found if I get ahead of myself and forget to create the variables first, then Visual Studio is NOT very forgiving, and will complain repeatedly just prior to crashing without the offer to save anything. If I add a new variable, it is like an easter egg hunt. This does NOT feel very single point of maintenance when variables must be used in this way to really effectively apply configuration, and it is so tedious and error prone, and unforgiving. I seem to spend a great percentage of time copying the names and datatypes and values of variables ONE AT A TIME. What is that all about?
I hear people telling the praises of configurations, but I must be missing something.
With DTS I used a system where global scope settings were "injected" into packages as they ran, and I never had to worry about anything, and it was damn hard to goof it.
Please someone, evangelize me!! Are people bypassing VS and using NOTEPAD on the packages or something like that to save time?

simple question:
I have create a web site in visual studio with form user authentication. Thats create a mdf database in this path:
c:inetpubwwwrootwebsiteapp_dataaspnetdb.mdf
thats use Sql server
i would like to access this database with c# form application on a network with multi-user.
if i change the drive letter of the path above to f: (mapped drive) or \serverc, i got this message
System.Data.SqlClient.SqlException: The file "h:InetpubwwwrootwebsiteApp_DataASPNETDB.MDF" is on a network path that is not supported for database files.
An attempt to attach an auto-named database for file h:InetpubwwwrootwebsiteApp_DataASPNETDB.MDF failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
i read that sql server did not support database sharing with mapped drive or unc share.
So how can i share website database with c# application???
Note: of course if i develop the website and the application on the same machine its work. I want this application run on several work station accessing all the same mdf database with his web user member.

Hey guys and girls,
This seems like a no brainer, but it's driving me nuts. I want one XML file for the entire solution. There are multiple packages in the solution which have different Connections in the conntion Managers. The packages share some connection names, and some are unique to the package.
Example:
LoadData.dtsx would have a source database connection named (SourceDB_OLEDB) and a oledb connection (DataWarehouse_OLEDB).
LoadDataMart.dtsx would use the same name for the (DataWarehouse_OLEDB) connection and have another oledb connection (DataMart_OLEDB)
I want one XML config file that has all the connection strings, but the problem is that the LoadDataMart.dtsx will throw an error:
Error 1 Error loading LoadDataMart.dtsx: The connection "SourceDB_OLEDB" is not found. This error is thrown by Connections collection when the specific connection element is not found. c:ssisLoadDataMart.dtsx 1 1
Thanks,
James

Hi,
I am facing a wierd problem working with SQL Server Mobile edition database. The code works fine for some time and then it suddenly starts throwing "There is a file sharing violation. A different process might be using the file."
I am disposing and closing the connection after each operation.
Please find the function code below which is being used for any database operation.
SqlCeConnection sqlCon = null;
try
{
sqlCon = ConnectionFactory.getInstance().getPrimDsConnection();
sqlCon.Open();
readCmd = sqlCon.CreateCommand();
this.prepareStmtManyRows();
dataReader = this.readCmd.ExecuteReader();
IList result = this.populateManyRows();
return result;
}
catch (SqlCeException sqlEx)
{
StringBuilder builder = new StringBuilder(
@"SqlCe Error in BaseReader.executeList() - ").Append(
sqlEx.Message).Append(':').Append(sqlEx.NativeError);
Log.getInstance().log(builder.ToString());
throw new DataAccessException(sqlEx);
}
finally
{
try
{
if( null != dataReader && ( !dataReader.IsClosed ))
{
dataReader.Close();
dataReader.Dispose();
}
if( null != readCmd) readCmd.Dispose();
if( null != sqlCon) sqlCon.Close();
}
catch (System.Exception ex)
{
}
}
I have also made sure that Query Analyzer is not running on my PDA.
I have been working on this since last one week but could not find a soultion.

Guys,
We have existing SSRS farm (3 web servers total) with single virtual IIS servers on each box.
We need to add couple more virtual IIS server on each box.
And these virtual IIS need their RS as well.
Web applications are written by independent vendors. They all have different IP/domain name.
All web app have own Reports & ReportServer virtual directories.
I was thinking of sharing ReportServer windows service and RS databases.
Is it possible? What would be best setup route?
Thanks,
