Accessing SQL Server Databases From Networked PC
Jul 23, 2005
Hello all. I have just built another PC (New PC)and have it connected to my
Original PC via a LAN. I have my SQL Server 2000 installed on the Original
PC. Both PCs use WinXP Pro OS. I believe I now have to install the Client
Tools on the New PC but after that, how do I access the SQL Server that is
on the Original PC. The SQL Server is setup with mixed (both Windows
Authentication and SQL Server Authentication). Just how do I use the SQL
Query Analyzer that I just installed on the New PC to connect to and
retreive data from the SQL Databases which are on the Original PC? Thanks
in advance for any help, Jim.

Hi everyone,
First of all I'd like to say I'm new to the forums, and in fact new to ASP.net.
I've had a couple of applications running in VB.net for the last year or so that I now am looking to move on and into ASP.net (main reason is to do with implementation to remote sites in foreign countries).
I'm currently following through the "Working with data and ASP.net 2.0" walkthrough on this site, which I must say has been a great help.
I'll start with the background stuff first
I have my main database on an SQL server. I also have 2 other databases on there - Customer and Employee. The reason for these are that they are shared amongst my VB applications and I kept them as seperate databases so that one database is all that needs to be administered and maintained, and these changes are then seen on both apps (takes away redundant data as well).
In my main database, main table, is a field called CustomerID. This value relates to the CustomerID in the Customer table. In my VB app all I do is have the user select a customer name, and then the customer ID value is copied to the CustomerID field of my main table when inserting / updating a row. This is simply accomplished with 2 SQL connections and 2 dataAdapters. I also use 2 dataSets - one for Customer, one for WorkRequests (the main database)...
I use ComponentOne stuff so that my grid will show the CustomerName instead of the CustomerID etc, and the same applies when I use my Employee database - I run many dataAdapters to this for things such as Account Manager, Technologist, Creator, UpdatedBy etc etc.
Now, I'm new to VS 2005 - my apps were created in VS 2003 and .net 1.1. Can I easily re-create my apps in ASP.net? My primary goal at the moment is to make sure I can load a row, and display the "lookup" values instead of the "integer" value. As my tables are in seperate databases, I would like to know the best way of accomplishing this, if it is of course possible.
Help and advice much appriciated.
Kind Regards,
Luke

Ain't sure if this is the right place. but anyway, here is the situation. I have 2 PCs and both are running Windows XP (A is using SP 2 and B is using SP 1) which are connected via a router and A can ping B and vice versa. I have SQL 2000 installed on A, so how do i go about setting up B so that B can access the database and tables of SQK 2000?Thanks.

Hi, I am developing a small asp.net application where I read from a readonly omnis database via odbc then dependant on user input write records to a second database.My first idea was to use an odbc connection to Omnis database and write to ms sql database. There is quite a few queries that need to be made to the Omnis database and I am binding a datagrid to the MS Sql server database. I was hoping to use stored procedures to update the mssql tables. So there will be much opening and closing of connections. Should I go down that road or should i think of using an Access database, with linked table to the Omnis database, then only one connection needs to be made. And I can store my information in the Access database tables. Thanks.

I'm new to databases as you probably can tell. A friend sent me three data bases, which in my mind should have been one database with all the tables included, but he didn't. So my question is, can you pull info from two databases in the same query?
I write the query acessing one database and the result chart must depend on a where predicate based on accessing tables in another database. If this isn't possible, how do I get the tables I need together, that presently reside in differing databases?
Thanks for the help in advance.

Hey, Everyone - I have downloaded two of the sample databases and get the following error when I attempt to open them:
Unable to open the physical file "c:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAAssets_Maintenance_log.ldf". Operating system error 2: "2(The system cannot find the file specified.)". (Microsoft SQL Server, Error: 5120)
So what am I doing wrong? The install of these sample databases is simple and straight-forward.
Thansk!

I am trying to determine if it is possible to add transaction support for a SSIS package. Here are the basic tasks:
Read New/Updated records from SQL Server
Update changed records in Access
Insert new records into Access
Update new records in SQL Server with Access key assigned on insert in previous step
Reset dirty_flag
I would like to wrap a transaction around this. If the package fails in the task that updates sql server with the Access key, the next time it runs, it duplicates the new records in Access because it did not finish the process. Is it possible to have a transaction wrap this entire process so I can undo the inserts to Access if I fail any subsequent tasks?
Thanks,
Steve

Hello,
I've written this stored proc, which have to collect records in one table in several databases. These tables contains very few records (1 to 10 max). In SQL Server standard edition, this stored proc is executed instantaneously. But in the Express, it could take 1 minute.
Is there a solution to this problem ?
Thanks in advance,
Best regards,
Guy

I am using VS 2005 to develop a Pocket PC 2003 application and for some reason I dont have the ability to assign my datasource to a SQL Mobile Database?
When opening Server Explorer, right clicking Data Connection, Add New Data Source, Change Data Source, the only options I get are
Microsoft Access Database File
Microsoft ODBC Data Source
Microsoft SQL Server
Microsoft SQL Server Database File
Oracle Database
<other>
I was trying to follow the tutorial
Step by Step: Developing a SQL Mobile Application with Visual Studio 2005
and SQL Server 2005 (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppcgen/html/med302_msdn_sql_mobile.asp)
and in that tutorial when they do the exact same thing it shows a screen shot that also lists 'Microsoft SQL Server Mobile Edition'
Any ideas why I dont have that option? FYI, I have SQL Server 2005 and have installed SQL Server 2005 Mobile Edition.
Thanks

I have several database files, all in the same directory. I want to write SQL statements that access two databases at once. For example, if only one database would be involved, I would write:
SELECT Test_Source_ID_column, Data_column
INTO Test_Destination_table
FROM Test_Sources_table
The above query copies two columns (Test_Source_ID_column and Data_column) from Test_Sources_table into a brand new table called Test_Destination_table.
Now the above query is fine for both the old and new tables being in the same database. But what if Test_Sources_table is in file Old.dbf and I want the new table Test_Destination_table to be in New.dbf?
Both Old.dbf and New.dbf are in the same directory. Therefore, there is no security issue about using ......etcpasswords. I should therefore be able to use relative paths. So, I also want to know how I can do that select on two databases in the same directory without typing long, long paths.
Is there a way to do queries that access multiple database files (all database files being in the exact same directory) AND use relative paths or no paths (and certainly not type a full path)?
NOTE 1: I'm using SQLEXPRESS, therefore do not have the SQL Server 2005 tools. I have Visual Studio 2005 Developer Edition with its tools.
NOTE 2: One table is accessed through ODBC. The other table is accessed through SQLEXPRESS.

Hi ,
I have around 5 databases with same structure used to store data for different locations and services.
I have created an intermediate database which will have all the stored procedures to access data from above 5 databases.
My queries are common to all the databases. so,I would like to pass database name as an argument to my stored proc and execure query on specified database.
I tried this doing using "USE Databasename " Command. but it says ...We can not use "USE command " in stored proc or triggers. so ..what i did is ..
--------------------------------------------------------------------------------------------------------------
CREATE PROCEDURE TestDB_access(@dbname varchar(100))
AS
BEGIN
DECLARE @localDB varchar(100)
Set @LocalDB=@dbname
if @LocalDB='XYZ'
EXEC ('USE XYZ ')
elseif @LocalDB='ABC'
EXEC ('USE ABC')
Select * from Mytable
END
---------------------------------------------------------------------------------------------------------------
When I run this from my database , it gives me an error "unable to find table "mytable".
What is the best way to make my queries work with all the databases.
Thanks in advance

Based on our database infrastructure, we need to secure our SQL databases. The security issue concerns on allowing a limited number of Domain Admin users to access the SQL databases.
We tried certain ways, based on the documents in the Microsoft web site, but we couldn€™t reach to the point of preventing the Domain Admin users accessing the SQL databases.
Thanks in advance.

We have a system that uses 3 databases, one for Membership db standard MS membership only the application has access to that data, one with User Data which we would like to make multi-tenant using Schema-Separation, and a third read-only reference db which is Common Market data for all users.we anticipate Tenant numbers in the thousands.Current we have multiple queries which create joins between the Main db and the Reference database using something like
Selec S.*, M.ScheduleDate, M.substation from Sites S left outer join Market.dbo.MarketUnit M where S.MarketUnitID = M.MarketUnitID
i'm planning to have a new schema for each Tenant on the Main Database, so I would create a Schema T1 for the first customer, a user T1User with access to T1 schema. and grant T1User access to Market.dbo. My First question is are there any concerns about the above T1User setup? My second question is, are there any tools which would automate the setup of the multi-tenant with schema separation, or should I just script the whole Main Database schema creation and replace schema name globally and then execute the script?
My Third question, how about upgrade and updates... currently using VS to compare dev/qa/prod database to identify changed which need to be promoted, and pushing updates... this could be a big pain to promote code to thousands of Schemas. grantedwe will likely keep the overall number of schemas spread over different SQL servers.

Hi All,
I want to connect to SQLExpress database on the network. I can do so using code but I want to use the Data Source Configuration Wizard. It seems this only works for local instances of SQL server. Is this true?
I can connect just fine to the database on the network using Microsoft SQL Server Management Studio Express...for what this is worth.
I have tried to map a drive to the SQL server machine and pick the mdf file but I get the error msg of network path is not supported for database files....I have turned on allow remote connections, allow tcp/ip, named pipes, added sqlserv.exe and sqlbrowser.exe to my firewall exceptions ect..
I want to be able to use Table Adapters, SqlDataAdapters ect. After reading numerous forum questions/ kb articles this seems to be a common problem. I am on the verge of just saying forget it and use MS Access instead.
Thanks in advance!

Hi
I have created a linked server from SQL Server 2005 (SP 1) to SQL Service 2000 (SP 4) with a sql server login that is available on both servers but with different passwords and permissions.
I am getting the following error while accessing the linked server in management studio based on the scenario given below ;
------ Error Message Starts
OLE DB provider "SQLNCLI" for linked server "(SQL Server 2000 instance name)" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18456, Level 14, State 1, Line 0
Login failed for user 'abc'.
------ Error Message Ends
Consider login name is abc.
Now this login abc has sysadmin rights on sql server 2005.
The same login abc has only db_datareader rights on sql server 2000 on just one database and is not associated with any fixed server role.
I have configured the linked server using the following options;
1. I have tried impersonating login from SQL Server 2005 to SQL Server 2000 .
2. I have also tried specifying remote login / password option.
Anyone having any idea, would be of great help.
Regards,
Salman Shehbaz.

Hi
If my site is hosted with an external company web host can I use ASP.NET pages to connect to a MS SQL DB that is on my company's internal server if I had MS SQL installed on it?
My company's server is always on and always connected to the internet.
I have access to my company's server if I need to set anything up on it for this to happen.
There will not be any kind of overload as the site is not accessed constantly.
Also, would this cause any kind of security leak? If so how would I go about plugging this hole?
Our server does have confidential info on it.
Cheers

Greetings. I am curently having problems with authorizations while attempting to connect to SQL Server with an Asp.NET web application. I will try to explain my problem as clearly as possible.
I am developing an Asp.NET web application with Visual Studio to connect and view a database on a remote SQL Server. In my Web.config file, I have added the line
<identity impersonate = "true"/>
In my IIS security options, I have disabled the annonymous authentication and enabled the Windows mode authentication instead. When accessing the database from my computer, by compiling and debugging my web application in Visual Studio, everything works wonder. When I try to use the web application from a remote computer using the IP address or from my own computer using localhost in the URL, it asks me for my Windows username and password, which I provide, and then refuses any further access, saying I don't have permission to even connect to the server.
How can I go around this and allow my users to connect to the server from a remote computer? My machine is running Windows XP SP2 and the server is running Windows Server 2003.
Thank you in advance for any help you may provide,
Marie

Hi,
I am developing a windows application that needs to communicate with a remote SQL server 2005 database. Server allows remote connections and MSDTC service also running. Do I need to run MSDTC service on the client machine where I use desktop application ? any ideas ? It's throwing some error like
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.
But my SQL Server allows remote connection, and I am able to do a select statement.
But when I insert/update anything, it's throwing this error. I guess some problem with MSDCT. Anybody have any idea ?

Hello all.
I am currently running a web server with Windows 2000 Server installed. It is a Pentium II 400 MHz, and also acts as the router on our network. I am worried that installing MSDE on this same server might drain the server resources, so I installed MSDE on one of the computers in our internal network. How do I set up my connection string to access the database on another machine in the same network?
Currently I use: Server="AnotherComputer";TrustedConnection="True";Database="MyDatabase"
When I use that, it tells me that the server can't be found. All computers behind the router have static IP addresses, but even when I type the IP address it still can't find the server. Any suggestions?

I have installed SQL Server on my laptop (full version), but can only access it while on the network. If I disconnect from the network, open Enterprise Manager, and click on my connection, I get the error "sql server does not exist or access denied". Why can't EM find my own machine? I even logged onto my own computer as a local user, instead of the network domain, and still recieved the error. Can someone tell me where I can edit (maybe my registration properties), so that I can run SQL server, while offline.

Hello All.
I need your advise on how I could access table from another server.
Let me explain what I am doing. Currently, I have 2 servers running parallel to one another other each loading from the same set of data into its own database in the night.
I would like to write a stored procedure to report the number of records from selected tables from the 2 servers to see if they match in records loaded. Thereafter, email me the results (I have already settle the sending of email part).
Have picked up some tips in this forum to come up with the below statements and it works fine for me: -
use AABBCC (database name)
select Server='Server 009', name, rows, SystemDate=getdate() from sysindexes
where name in ('invoice_line', 'invoice_line_import', 'sales_order_line', 'sales_delivery_line','Cust_dely_reliabity','sales _order_proc_time','AU1016','NZ_Data')
order by name
Result: -
Server Table Name Rows
Server 002AU1016 0
Server 002Cust_Dely_Reliabity 5017342
Server 002invoice_line 4397800
Server 002invoice_line_import 12120
Server 002NZ_Data 649745
Server 002Sales_Delivery_Line 5323875
Server 002Sales_Order_Line 5356989
Server 002Sales_order_proc_time 3651362
Instead of running the above scipt or stored procedure from 2 servers and received 2 email (one from server 002 & one from server 009), I would like to access the other server within the same stored procedure.
I have used sp_addlinkedserver (may not be the correct method) and <servername>.<databasename>.dbo.sysindexes (doesn't work)
Please help. Thanks a million.
The desired result could be:
Server 002 .....
Server 002 .....
.
.
Server 009 ..... (result from the 2nd server)
Server 009 .....
.
.
Best regards

Hi
I have an application written in classic ASP which uses Windows Authentication in SQL Server.
This seems to work fine, except when we try to write to the database in Session_OnEnd in Global.ASA.
We don’t get an error and although logging is enabled in SQL Server, no failed logins are reported. Nevertheless, the database is not updated.
I’ve tried adding the IWAM_Servername user to SQL Server, but that hasn’t made any difference.
Has anyone any thoughts on how to rectify this? At the moment, both SQL Server and IIS are running on the same PC, but we need to find a solution when they are on different PCs as well.
