Send Sql Statement From Vs2005; Detach A Mdf File From Sql Server Express
Sep 17, 2007
Hi,
as I'm relatively new to Sql Server Express, I have a few questions regarding best practices for data handling.
In my ASP.net Application I thought it might be of high value to create the database as mdf file in my vs2005 project,
so I could easily copy the database with the project.
Now inside VS2005 I have the problem of not being able to create any SQL Statements other than queries. For example simple create table statements and such seem not to be possible if I don't want to use the designer.
So I attached the mdf file to my Sql Server Express in Sql Management Studio Express.
But here I seem not be able to detach the file again when I made some changes. Only option is to delete the whole thing.
So my questions are:
1. Is it somehow possible to send simple sql statements to a sql server express database from Visual Studio 2005?
2. How can I detach an mdf database file from Sql Server Express once I have attached it with Sql Management Studio Express?
3. Should I use a different approach to my problem?
thank you all in advance

I am using the following C# code to establish a SQL connect to a SQL database file:
// connection string
// attach a SQL database file to a local SQL server express instance
string _connectionString = @"Server=.SQLExpress; AttachDbFilename=C:BalanceDatabase_1.mdf; Trusted_Connection=Yes; User Instance=True";
// using System.Data.SqlClient;
SqlConnection _sqlConnection = new SqlConnection(_connectionString);
// open the connection
_sqlConnection.Open();
// do something
// close the connection
_sqlConnection.Close();
So far, the connection works fine.
However, next, I want to copy the database file to another folder. So the following codes:
// source database file name
string sourceDatabaseFileName = @"C:BalanceDatabase_1.mdf";
// target database file name
string targetDatabaseFileName = @"D:BalanceDatabase_1.mdf";
// copy database file
System.IO.File.Copy(sourceDatabaseFileName, targetDatabaseFileName, true);
Then the program came with runtime exception: "IOException was unhandled: The process cannot access the file 'C:BalanceDatabase_1.mdf' because it is being used by another process."
Is it because the database file was sill attached to the local SQL Server express instance? What can I do to bypass this problem? Detach the database file? or dispose the local SQL Server express instance?
Many thanks indeed!

Hello all,
I use Visual Studio 2005 Standard. I would like to know the best way that I can create Sql Server 2005 Express databases visually since VS2005 Std. does not allow me to do it.
Any help is appreciated and thanks in advance,

I'd be interested in knowing how VS doesn't allow you to create a database. What error are you getting?
There are two ways to create databases, depending on your goal:
To just create a database on your server, do the following:
Open the Server Explorer
Right-click on Data Connections
Click Create New SQL Server Database
Specify Server Name and Database Name
Your database will be created and you can start working with it.
Embed a database in your project:
On the Project menu, click Add New Item.
Select SQL Database from the list and give it a name.
Click OK
This will run you thorugh a wizard to create the database.
If your having problems doing either of these, you may not have SQL Server installed on your computer or VS might be pointing to the wrong Instance Name. Check out the Option dialog under Database Tools:ata Connection and verify that the correct instance is specified.

I am trying to create a similar project and I also recieve an error while trying to create a database...
"An error has occured 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.
(provider: Named Pipes Provider, error: 40 - Could Not Open A Connection to SQL Server."
Now let me explain what i am trying to do ...
I am trying to create a web interface for the data that I want to store in the SQL database. I have installed VS2005 & SQL Server Express 2005 on my local machine. I want to develope this project on my local machine and then transfer it to a server once i have finished the project.
If i am doing this all wrong, please let me know !

Hello All,
I had VS2005 in my machine and was working with a mobile device using Sql Server CE. While compiling and deploying device application to my mobile device it used to deploy the Sql Server CE cab files also.
But now i have migrated to another machine ( Vista OS ) and installed VS2005 newly etc., Now when i try out the deployment of device application to my mobile device it is not deploying the Sql Server CE cab files but just copies the SqlServerCe dll file.
So when my application launches in the mobile device i get an error can't PInvoke sqlceme30.dll etc.,
I know that i can manually copy the cab files to my device and work. Its little tedious. Can anyone tell me how to achieve the behavior of my old VS2005 wherein it automatically deploys the SqlServer CE cab files? Is there a setting in VS2005 to enable this. I read in one of the posts that we can go modify the option Tools->Options->Smart device and enable an option to deploy the latest updates etc., But i couldn't find such an option in my VS2005.
P.S: I have installed my SqlServer Mobile edition 3.0 SDK to the default path under program files. Should i install it under VS2005 smartdevices SDK or something like that? I tried that also but still no success.

Good Evening All,
I've serached this forum and Google'd for a resolution to this issue, to no avail. Here's the scenario:
I'm running VS 2005 on Windows Media Center laptop and need to create ASP.net membership for my web application built using VB. I have SQL Server Developer installed with instance name MSSQLSERVER. Previously, I uninstalled SQL Express and installed Developer edition and can now open and utilize Management Studio.
Now, when I try to create a new SQL Server database in my solution's App_Data directory, I receive the above error. I already changed instance name in VS2005 per Tools-Options-Database Tools-Data Connections to MSSQLSERVER.
Could someone provide me with a list of procedures to ensure proper setup of VS2005 with SQL Server Developer Edition?
Thanks much for your help.

When I send my query results to a file in SQL Server Management Studio, how come I'm seeing the following in Notepad++? FH TEST "FH" which I thought should be in a CHAR(2) data column is there but "TEST" seems to start in Column 6...not column 3 as I would have expected. I was expecting... FHTEST.

Need help
I made a mistake an attached a read only database to the server (now it is grey marked).
When I try to select this read only database in the MS SQL Server Management Studio, the server hangs up.
I removed the read only attribute from the .mdf and .ldf File and made a reboot of the server. Still the same problem.
How can I detach this read only database or how can I set the attribute to read/write (always hangs up the server, when I try to access this db)
I tried also:
alter database readOnly_dbname set read_write
or
USE master;
GO
EXEC sp_dboption 'readOnly_dbname', 'read only', 'FALSE';
Many thanks for an answer.

I am developing a C# mobile 5.0SDK app that utilizes SQL2005 Compact Edition device files on Vista using as far as I know the latest SPs and versions.
Last night, I could open tables from the Server Explorer .sdf file, see the contents, edit the schema, etc. Now today, I assume all of a sudden,I am able to open schema but cannot open the table to see the contents. I get:
Microsoft SQL Server 2005 Compact Edition captioned error dialog box that says "Access to the database file is not allowed. [ File name = ],[,,]
Using Sql Server 2005 Management Studio Express, I can open the table, do queries etc. I have tried rebooting, deleting, opening old projects, deleting dataset, disconnecting mobile device, but I still get the same error. I have tried stopping the SQL Server(SQLEXPRESS) service on the server but get:
Cannot open MSSLQ$SQLEXPRESS service on computer 'p5w64'. Access is denied.
I have no idea what to do next to start moving forward again, other than try the XP environment which I will do next.
Has anyone experienced this problem?
Thank you.

When I try to add a new database to App_Data in a VS2005sp1 project I get "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user interface".
I have SQL2005sp2 and SQL Express on the system, both services are running, and an instance of the latter called SQLExpress which I can use through SQL Server Management Studio. sp_configure user instances enabled is set to 1. The SQL Server Instance Name in Options | Database Tools | Data Connections is set to SQLExpress ...
I have no idea how to proceed .. any ideas anyone?

Can I do that using DTS. I need the answer very quickly.
Any help would be appreciated.
Or there is any better way to transfer the content to the table.

Hi,
I have a 44 gig db that I moved to another server via the NT copy and paste method. The db has gotten a little larger, and now NT gets almost to the end, but can not complete -- either starts over completely and just does the last few minutes over and over.
Is there an NT copy and paste limit? Any ideas what the problem is? Is the db mixed up?
Thanks for any help.

write a backup to local disk and then run a command to send the file to the TSM Server.This is the command I use at a Command Prompt to do an TSM incremental backup.
Command for an incremental backup of drive letter h:
C:Program FilesTivoliTSMaclientdsmc incremental h:
Command for an incremental backup of a mount point:
C:Program FilesTivoliTSMaclientdsmc incremental -domain="E:Backup"
I would like to be able to run this as the last step in my backup processes. This would allow me to send my local backup file to the TSM server to write to tape.
I am looking for either a CMDEXEC Expert that could show me the syntax to run these commands via a direct command or a batch job. The other option would be to run these commands via the Powershell type.

I have a vs2005 deployment project and have set prerequisites to include sql express. This is not what I need however since I need the advanced version with full text search.
How can I make sure that the advanced version of sql express is installed when my app is installed?
Is there any way to include the setup bits for adv. sql express in my install so the user doesn't have to connect to the internet? I know this is probably doable, just wonder if there are any specific docs or examples?
I have SQLEXPR_ADV.EXE and know the options for quiet install, but how to integrate into my install project?

Hello everyone, recently I experienced a weird problem on my sql host, and my service provider sent me an email told me that my database encoding didn't match their standard. in the mail they said their standard was "SQL_Latin1_General_CP1_CI_AS" and my database was "Latin1_General_CI_AS". I did some research on google with no luck, most of them involved command line and stuff, which made me totally confused since I'm a sql server newbie.I created this database using VS2005's wizard, with all default settings. Therefore I hope someone here could help me out. thanks in advance.-yonk

I am trying to send a csv file with 15000 records via the database mail in SQL Server 2014. The problem is that when I open my email the csv only contains 209 records. I have tried the same thing in SQL Server 2012 and it works as expected - it sends the 15000 records in the csv.
I have tested this on several sql servers with 2014 edition on them, and I have the same issue on all of them. The query breaks off at different points on each sever - for example one of them breaks off at 209 records as i said above, another one at 307. The last record always gets truncated at the same place. The csv attachment size it's about 64 kb - which is well below the 4MB limit i've configured the database Maximum File Size bytes parameter.
What i am doing basically is creating a job that is meant to execute a stored procedure and send the results in a csv in an email. The stored procedure is something like:
select col1, col2, col3
from table A1
where col1 > 1000 order by col1

the testInsert.dbf has the feilds of: Name( string format) & Amount(Decimal format)
Dim Conn as String
Conn="INSERT INTO testInsert.DBF VALUES ('shippers06','625.06')"
rs.Open(Conn,db2)

I have an SSIS package that I created that looks like the following:
Execute SQL Task [Determines the file name]
Data Flow Task
Source - Query [Grabs the data]
Destination [Saves data to file on network drive]
Send Mail Task [Tells user to get file from network]
When I run this package inside Microsoft
Visual Studio I get the results I want. It sends the file to the
network drive and because there are SSN's in the file, it doesn't
actually e-mail the file but puts it in a secure location for the
person to get the file.
When I schedule this in SQL Server 2005 I get the file saved to: c:windowssystem32dynamicfilename.csv
So somehow it is still able to determine what the file name should be, but instead of sending the file to the right destination when you run it through VS, it flops out and sends it to this wacky directory.
I've
spent too much time on this and was wondering if someone can point me
in the right direction without going to the extent of writing a script
like this suggests. thread1555-1265108
Thanks,
Keith

I have an issue with a DTS package. We create a zip file and then attach it to emails going out using DTS. The problem is that the attachment, when received, is named using the full path to the file, so it is quite long.
Has anyone seen this before? Is there a way out of this?
I am considering mapping a drive to the share holding the file to be named, but the fact is this will shorten the name but will still result in the path being included.
I am wondering if this is a bug, as I suspect this isn't the default behaviour.
Thank you in advance.
Dave
