Why ConnectionString Varies On Different Servers.?
Jan 8, 2007
Hi all,
I want to connect to an SqlServer database and I have given the connectionstring on an WinXP computer as
Dim ConnectionString As String = "server='localhost'; trusted_connection=true; Database='domains'"
Now, when I copied the files to another computer which is Win 2003 Server, I had to give the connectionstring as
Dim ConnectionString As String = "workstation id=INFO0;packet size=4096;integrated security=SSPI;data source=INFO0;persist security info=False;initial catalog=domains"
Now, I want to upload the files to a website called "BrowseNow.com".
What should be the connectionstring when the files are being uploaded to the server.
I want the public to read from and write to this database tables.
Is there anything I should do witht the SQL Server Enterprise Manager?
Thanking you in advance,
Tomy

Greetings,
I have a somewhat complex stored procedure running on 3 production servers. On 2 of the 3 servers the stored procedure executes in three seconds. The stored procedure runs to completion on the 3rd production server but requires 8 minutes to complete.
The sproc contains a single query that contains correlated subqueries that each call the same user function. If I copy the sproc's query and execute it directly from Management Studio, the query runs in 3 seconds, just like the stored procedure on the other two production servers. The sproc has one parameter.
I have updated statistics and recompiled the stored procedure and user function (on the 8 minute server). That doesn't help. I have used the WITH RECOMPILE option in the stored procedure. The query execution plan for the stored procedure is not the same execution plan prepared for the sproc's query when it is run on a standalone basis. I'm no expert with execution plan analysis but I can see significant differences between the sproc and the sproc's query.
The 3 servers are supposed to be identical in hardware and software configuration.
Can anyone provide any insight into what might be going wrong on the 8 minute server?
Thanks,
BCB

Every night we use sp_attachdb to attach a 1TB database to our datawarehouse server. Each night we kill off all nonsystem related spids, setall the other databases to DBO only and then attach. The attach seems totake between 4 minutes to an hour. With an idle server and filegroup sizesthat have not grown what could be causing the variance? The number oftransactions to rollback or forward doesn't seem to have an impact. The logindicates that the attach is spending almost all its time in phase 2.Anyone know exactly what happens in phase 2?Books online and reading the sp_attachdb proc weren't much help.sp_attachdb is simply a derived call to create database ... for attach.Any insight is appreciated.Thanks,Ray

I have a query that varies depending on control values. For example, what comes after the SELECT, FROM, WHERE, or ORDER vary with what table they need to look in, how they want to look it up, what value they are looking for, and what order they want it displayed in. There are too many possibilities to write seperate queries for. The data found goes to a dataset and gets bound to a gridview. This is done inside a vb sub.
I tried to make a similar query in a selectcommand inside sqldatasource tags with if-then-elses in <% %>s but got an error saying something like "constructs were not allowed inside tags."
How do you make a varying query as a selectcommand inside datasource tags?

If I have two NT accounts and performance using one account is prettyawful what might be the most likely reasons for the difference inperformance?We're talking about a few hundred thousand rows being returned from aSELECT statement within a stored procedure with a few INNER JOINS.

I know that if I set the Package.MaxConcurrentExecutables Property to -1, it will execute the maximum number of concurrent running executables to equal the number of processors plus two.
I have a requirement where I have to run the maximum number of concurrent running executables. However, the number of concurrent executables to run varies each month (it is not fixed).
If I have a loop inside the package that executes each stored procedure (same sproc, different parameter), will SQL Server execute the maximum number of concurrent running executables possible? (It may execute 4 or 8 at a time and that is fine.)
Thanks,
Michael

We have a winforms application with local rdlc reports. Â On Surface Windows 8 Pro devices only, reports render such that they are scaled down and don't fill the page. Â If resolution is lowered on the device, the report scales up to fill the page.
 This affects the appearance in print layout and well as the actual printed size.
If we export to pdf, it renders to fill the page (as expected). Â If you print to pdf or to printer, the scale is shrunken.
If we change the resolution settings so that "Make  text and other items larger or smaller" is set to small, the issue is resolved except the tablet is not very usable on this setting.Is this a bug?

What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config
The CCWW is my PC's name, normally I can connect to the database ASPNETDB.MDF correctly either Part 1 or Part 2 in a web page,After I open Database Explorer panel and browse ASPNETDB.MDF, I can't connect to database using Part 2 when I open a webpage in Microsoft Visual Web Developer 2005 Express Edition,but I can correctly open a webpage using Part 1 after I open Database Explorer panel.
What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config?
I guess while I use Part 1 to connect, maybe it will be cancel exclusive method of the database ASPNETDB.MDF first, but when I connect to database using Part 2, maybe two programms both Part 2 and Database Explorer visit ASPNETDB.MDF at the same time!
--------------------------------------Part 1------------------------------------------------------------------------<add name="MyConnect" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF" providerName="System.Data.SqlClient" /> --------------------------------------Part 1------------------------------------------------------------------------
--------------------------------------Part 2------------------------------------------------------------------------<add name="MyConnect" connectionString="Data Source=CCWWSQLEXPRESS;Initial Catalog=ASPNETDB.MDF;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF" providerName="System.Data.SqlClient" />--------------------------------------Part 2------------------------------------------------------------------------

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!

can anyone tell me if they know of a way to automate the update process from development servers to live server, with little interference from an administrator
I have a development team that are constantly updating their databases along with their ASP code, and want to publish changes an a weekly basis. They have asked me for a way to take their new structures, tables, procedures etc, and copy them to the live servers, but NOT to interfere with existing customer data.
Funny I know – and I hate the idea btw :(
Any references, contacts, 3rd party tool recommendations welcome,
Thanx,
Darren

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.
1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.
Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)
If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.
Thanks!

I have completed a windows db app.
I have saved the db files in the application/bin/ folder.
The connectionstring that i am using is
Code:
sql
Server =(local);Data Source=.SQLEXPRESS;DataBase=;Integrated Security=SSPI
say i wanted to install this app on my home computer, does not have sql express or anything installed.
Now i want to use the application and it must read/write data from the sql db that was saved in the application/bin/ folder.
what is the connectionstring then ?
can anyone please help ?
what im trying to say is that the application must work independent from any SQL manager/express etc.
is that possible ?

<VS2005, SQL Everywhere CTP>
When I create typed datasets (for SQL Everywhere db) using the VS designer, I get a connectionString like Data Source =".App_DataDb1.sdf" added to the settings file by the designer. This works fine in the designer but not at runtime. If I replace the settings value to Data Source ="|DataDirectory|App_DataDb1.sdf" then it works fine at runtime but breaks the designer. I looked at the typed dataset designer generated code & it creates a SqlCeConnection object which supports |DataDirectory| macro. So, how can I get the designer & runtime to agree on a connectionString. I guess I can create a partial class for the table adapters & force a connectionString at runtime via a constructor overload, but, is that my only option?
Btw, the error I get at runtime when using the designer generated connectionString is:
"The path is not valid. Check the directory for the database."

hi,
I'm having this application using the express way to create the dategridview by having the query string builder. However, my computer recently crashed and I have no idea to change the connection string. so when I load the whole windows application, I am unable to view the information that are supposed to be in the datagridview. however, it returned an exception.
after finding out the main culprit, I realised that the database is using the old sql server's login. since it is using the old database's login, therefore it is unable to log the information into the datagrid view.
Please help! Thanks.

In short, I have a couple grid views on a page that are used for editing as well as sorting, etc. The grids are setup to use the SqlDataSources. I'm trying to deploy this to a server environment for different instances (test,cert,prod) and am trying to set the ConnectionString for the SqlDataSource in the code behind (Page_Load()). Everything works well, except, I get an error message that says the "ConnectionString Property Has Not Been Initialized." Its a javascript alert coming up on top of the grid view.
Here is how I'm trying to set the ConnString in the Page_Load():this.EmployeeTimeCardDataSource.ConnectionString = ConfigurationManager.ConnectionStrings[connStr].ConnectionString;
Here is an example of the DataSource.<asp:SqlDataSource ID="EmployeeTimeCardDataSource" runat="server" SelectCommand="sp_Select_Managers_Employees_List" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:SessionParameter Name="CurrentUser" SessionField="User" Type="String" /> </SelectParameters></asp:SqlDataSource>
