Ms Sql Mdf Database File Attached Vs Created On Sql Server
May 27, 2007
Hi all
I have a question concerning sql database mdf files. In the old days I would user a ms access database. This file would be stored with the actual web files and would utilise a dsn connection.
I have noted when designing with vwd 2005 express it allows you to use 2 methods of creating a mdf database. You can either create it as an attachment mdf or you can create it directly using sql manager.
My question is, if you create the mdf database as an attachement file can you store it in the same manner as if you where using a ms access database, meaning can you store it with the web site's files so it uses the file storage allocated size and then create a connection similar to a dsn (but for sql) to the isp's sql engine or does it have to be uploaded to the isp' s sql server.
The reason for this question is some of my customers do not want to pay the extra cost to have an sql allocation, however I do not want to go back to using old asp methods to create advanced sites as I prefer using stored procedures.
Hi all (newbie @ asp.net)(oldie @ ASP 3)What is the purpose of using an attached MDF database files in the App_Data folder on a web site as to importing it into the SQL server directly or creating it on the SQL server. Does a mdf database attached file purely use the SQL server as a connection interface.Is it something similiar to DSN(ODBC) Connections for ms access databases.
I attached .mdf and .ldf from the app_data folder in an asp.net web site. I set the configuration to SSPI. The trouble is, I get this error requested by the login. The login failed. Login failed for user 'IN-XYZmattaniah'.
If I create a database and connect to it using SSPI I do not get this error. I assume there is something I am missing.
Hi every body. As you can see in the title I would like to import my tables from the data base which is in the SQL Server, to an mdf file which can be attached to the project.Can some one give an indice please?
I was wondering about the principles of SQL Server. In all of my books, they show me to attach the DB, even create the DB through Visual Studio 2005. Which creates a .mdf file and a .ldf file.
Ok, but I cannot open those files through SQL Server Management. The only DB I am able to manage through SQL Server Management is the ones created with it.
So my question is: For a Multi-User type Application, is there a problem to attach a network based file through VS2005, the same way as an access file ?
Again my keyword here is Multi-User. Sorry if this myth be a stupid question but I am used to MSAccess. SQL Server is a lot more complexe and I don't want to start in the wrong direction.
our clients have the flexibility to detach and attach databases (I know there are a lot of considerations around this but there is now way of changing it), once they attach a database we need to run some code to update a bunch of values in the database.
Other than creating a SQL Agent job are there any other options available to automatically execute a script once the database has been attached?
I needed to recreate/publish a DDL and data file(of a database) that was produced using Database Publishing Wizard. The size of the file is 4G. I receive the following error when I try to open it up in the new query window of sql server 2005 (sp2)for execution.
"The operation could not be completed. Not enough storage is available to complete this operation."
I know my server has 829G of free storage space available. i receive no errors when I open up a smaller file also created by database publishing wizard.
trying to get a new database created then running a script to created the tables, relationships, indexes and insert default data. All this I'm making happen during the installation of my Windows application. I'm installing SQL 2012 Express as a prerequisite of my application and then opening a connection to that installed SQL Server using Windows Authentication.
E.g.: Data Source=ComputerNameSQLEXPRESS;Initial Catalog=master;Integrated Security=SSPI; Then I run a query from my code to create the database eg: "CREATE DATABASE [MyDatabaseName]".
From this point I run a script using a Batch file containing "SQLCMD....... Myscriptname.sql". In my script I have my tables being created using "Use [MyDatabaseName] Go CREATE TABLE [dbo].[MyTableName] .....". So question is, should I have [dbo]. as part of my Create Table T-SQL commands? Can I remove "[dbo]."? Who would be the owner of the database? If I can remove the [dbo]., should I also remove dbo. from any query string from within my code?
Background: I've created an application to run on windows mobile 5.0 devices. It replicates to a publication on a server. To do this it goes through ASP.net. This creates the database on the Mobile Devices.
Issue: Problem is the initial download of the database is taking 2hours plus to replicate (create) for the first time. So I'm trying to create the .sdf file on the server, zip it, and send it across to the handheld. All subsequent replications take about 5 minutes.
Question: Does anyone know how, or have examples for creating a Mobile CE database on the server. I need to create it using ASP.net and go through a pre-existing publication where a hostname used for filtering.
http://msdn2.microsoft.com/en-us/library/ms173009.aspx explains how to create this in SQL Server Management Stuidio. How do you do the same thing over ASP?
Can this be done using SMO? How do you create a SQLServerCompactEdition database using normal .NET Framework? Thanks for your help!!
I attach my SQL Server Express data file to my host. I would like to copy all of my member information back to my local computer. How can I do this? My host won't allow my to physically copy the data file over. My host is discountasp.net. Thanks,Jeff
I'm having some problems with SQL Server 2005. I installed the Personal Starter kit but don't have the Express edition installed so I attached the .mdf file to SQL Server 2005. That's ok and I also changed the connection string to integrated security.<add name="Personal" connectionString="Data Source=MyTestServer;Initial Catalog=Personal;Integrated Security=True" providerName="System.Data.SqlClient"/>I tried setting the security settings in the Management studio under Security | Logins | BUILTINAdministrators where I select the User mapping and check the checkbox before the Personal.mdf file. But this doesn't seem to do the trick. How can I set the correct security settings?
I need to extract a attached file which is sent via email. I believe that I can do this via SSIS... but I would like to know how... Could you kindly send me any idea about how can I do it?
Hi all,I have a problem and need some ideas.What I have done: I created a page to upload an excel file into a SQL Server table along with some customer info (from the login, day, etc.). This excel file contains several rows (some of them may be blank) and columns (also some may be blank). The file is stored in an image object.The file will be checked (they want to do it manually, because contents is a problem). If they say it is OK, I want to run a program to add a record into an existing table with the request no. (from the first table, where the object is stored) and all the information available from the filled rows (first row is header). I have a column, which can be checked, if the row contains data or not.Any ideas?I know how to read from and write the contents of the object to a field in the SQL table. Can I use this?Thanks for any idea / code / link.
Hi, I was trying to figure out how to back up a database that has been attached to the SQL Express instance. I found on the web this tutorial and tried to use it, however it seems like it cannot find the database. The DB is attached by the web application using AttachDbFilename in the connectionstring. http://www.sqldbatips.com/showarticle.asp?ID=27 Any ideas? thanks
Hello all, I'm using SQL 2005 Express edition. I'm currently connecting to the database file directrly (from ASP.NET) and that db file is not attached to the server. My question is this: What is the difference ? Will the performance improve if the db is attached and I connect to it throught the server ? I'm really not sure what the difference is. Thanks
I need help getting all the users that are "attached" or "allowed" to access a given database and their login information. I do not know if this is even possible but I had tried to do my own research and cant figure it out/find any info on it. Any help is greatly appreciated!
I attached my database to SQL 2005 but it's showing up as read-only for some reason. I've attached this before just fine in another instance of the Vista OS. Why would it attach differently this time compared to all other times and show read only?
The .mdb and .ldf files are not read only if you right-click and check out their properties.

I am in process of moving a SQL 2005 solution from a development box that used local storage to UAT environment with SAN attached storage. The solution uses database snapshots
The database files are on the SAN storage but during testing I was unable to create a Database snapshot on the SAN disk. Creating snapshots on the local disk worked fine.
Is their some restriction/problem in using the database snapshot technology with SAN storage?
I am a new SQL Server developer using Visual Basic 6 Professional Edition. I am using ADO and SQLDMO to develop my application. The SQL Server is Version 7.0, SP2 and SP3 (two different servers).
I am having difficulty gaining access, using ADO, to databases I create using SQLDMO. I create the database, create the DBFILE object, create a login and attach it to the database, create a user, assign the created login to the user, and assign the created user to the 'db_datareader', 'db_datawriter' and 'public' roles. the login object was set to 'standard', not NT. the SQL Server is set to 'mixed' NT -SQL Server login mode. Thw SQL Server is running under the 'system account'. Using SQL Server Enterprise Manager, everything looks OK. An attemp to connect using the ADO connection object fails, giving an error of Login failed for user 'engbom3admin'.
Connecting to the SQL Server using SQLDMO uses the 'sa' user name with a blank password.
I can successfully connect to the created database using the ADO connection object using the 'sa' user name and blank password. Using the SQL Server Enterprise manager, I cannot see anything at all different between the 'sa' and my created 'engbom3admin' user. I've manually set the created user to have 'db_owner' roles, etc. Same result. I'm stumped. I've read all I can gather from the Microsoft SQL Server books. I'm still stumped.
I would greatly appreciate any help, information or tips you could provide. Thank you in advance.

Hello, I was using a SQL Express database for some time now with no problems for a NUnit Test project. No, all of a sudden, I'm getting these problems: DatabaseProviderTest.TestContainsUser : System.Data.SqlClient.SqlException : Cannot open user default database. Login failed.Login failed for user 'XXXXXX'. For the SQLEXPRESS database, I checked and I am a user, and I gave myself every permission imaginable. The default database is master, so I don't know why I am getting this problem? Any ideas? Thanks.
Why in the hell doesn't SQL Server provide a facility for dropping anactive connection on an attached database in SQL Server Managementconsole? I can't detach an attached database because apparently thereis an active connection.I know you can use SSEUTIL but it seems like kluge for a poorlythought out function.Crazy
I am supposed to be documenting the SQL Express 2005 SP2 installation and connection to our application on Vista. I have installed and uninstalled the application several times in trying to create the connection and document the process. I thought I was done but now the database will not attach because it thinks the databasse is already attached. The database is not attached. I even uninstalled it again thinking something was left over.
Among the possibilities are that the database we are trying to attach is from SQL Server 2003 on a Server 2003. I tend not to think it is a server issue but have no reason to make that statement.
I tend to think it is a Vista issue because I have encountered and circumvented several. Our applications work fine on the full version of SQL. I can connect my Vista computer to the servers without issue. We have no Vista Servers other than the workstation I am trying to get SQL Express running on.
I am about out of ideas. Any suggestion will be tried at this point. Brian
In my vb.net application, I have an attached database called dbMaster with the following tables:
tblCustomer, tblProducts, tblUsers
In visual studio 2005, is it possible to publish only one table? My problem is, is that I want to send my end users updated data from my tblCustomer, and am finding that on my test laptop, if I publish dbMaster, it sends all tables when I just want one to be sent.
I have a package in which there are only one Data flow Task and it has only three components. 1) Source , which is a SQL db 2) destination and 3) OLE DB Destination flat file Error output file. I want the error file to be created ONLY if there is any error while dumping the data into destination DB. But , the issue is, the error flat file is being created inspite of No error while dumping the data from Source to Destination.
Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
Using VWD 05 Express & SQL Server 05 Express, how do I transfer my database to my host that is using SQL Server 2005. On the SQL Server express web site http://msdn.microsoft.com/vstudio/express/sql/powerful/ one of the features listed for SQL Server 05 Express is: Transfer any database created in SQL Express to other editions of SQL Server 2005. Thanks
