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.
Hi allI 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. Any help will be appreciated

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.
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
Is it possible to try repair a database without being attached, giving the path to the files?
I'm trying to attach a database that i recover from a disk, and i'm not able to attach, gives me an error, saying i should do a db check.
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.

I have created a database in Visual Studio 2005 by adding a new "SQL Database" item to my project, and then designing the tables with Server Explorer.
How can I add this database to my local instance of SQL Server Express, and to my SQL Server 2000 database engine?
I downloaded the SR2 - major mistake Now I cannot get into the sample databases I have on my machine. I can attach to the Servers, but they have SR1 and now I guess if I would make changes from my SR2, then they will be screwed up.
My error when I try to log into my machine (adventure works) is:

I am testing out a blank database created over two physical files on two separate disks with one table called data which has one column called values nvarchar(max).
I filled the table up with a whole load of data and ran a select * against it. If I run Permon at the same time I can see that the read load has been spread over multiple disks as each of these disks is getting read from in parallel. If I create the same database on a single file and run the same select * again it takes much longer, proving that the read load has been distributed across multiple disks.
Now moving onto writes, this is where the confusion lies. I understand that SQL server fills files evenly until they need growing, after which it will then fill files individually until they are full in a round robin fashion unless you have trace 1117 turned on. What I don't understand is why the writes aren't distributed out whilst it is filling these file groups.
I ran an continual insert into my table with go 1000000 to monitor how the files are being filled up. I monitored where SQL server was physically placing the files as they were being inserted by running the following query:
;WITH CTE AS
(SELECT
sys.fn_PhysLocFormatter (%%physloc%%) col1,
RIGHT(LEFT(sys.fn_PhysLocFormatter (%%physloc%%),2),1) AS [Physical RID],
DATAID
[Code] ....
I could see that it would a thousand or so records into file 1, then a thousand or so into file 2, then a thousand or so into file 1 etc etc. In another words it would hit one disk, then another disk, then back to disk one to fill the file evenly. Is there any way to make SQL Server distribute the writes out in parallel so that both disks are writing in tandem?
By the looks of it, multiple disks only scale reads, as with writes only one disk is ever written to at once which is annoying. Any way to harness the write power of multiple disks?
Hello:
I am still working on my project, but figured I would share my findings with the community, on how I imported my SQL Server database tables into a new SQL Compact Edition database. Unfortunately, I haven't figured a workaround to the IDENTITY_INSERT issue, but other than that, I will proceed.
1) I downloaded and played with the tool presented in the article "Generate SQL Insert statements for your SQL Server 2000 Database" I made the following modifications . (my modification can be found here)
a) Disable scripting dependencies
b) Add a filter for objects to script
c) Prompt for each table from which to export data
2) From the scripts output by this tool, I had to (which I may integrate into the tool later... who knows)
a) Remove 'On Primary' statements after the create table statements.
b) Remove date defaults.
c) Most other SQL generated by the tool seemed to work.
3) Execute each 'Create Table' statement individually.
4) For the Data Import, I had to add semi-colons to the end of each Insert Line.
5) I Have found no workaround for the IDENTITY_INSERT issue. If anyone has a good idea, I would love to hear it. In my case, I was importing the DotNetNuke core store module tables populated with about 2500 products and 20+ categories consisting of a simple categories table and products table. I imported the categories table into a fresh MS Access database file, and then ran the update query against the attached products table in the original SQL Database, then regenerated the insert statements, and imported the data generating fresh product ID's. This database will only be read only, so it didn't matter about maintaining the Product ID's, just the relationship between the products and categories.
Separately, I found a great blog article on how to embed a SQL script as a resource for your application and run it on your applications first run, so my steps above would provide a quick foundation for generating that sql script.
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?
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?
Dear friends
I need to report the amount of free space in each datafile of a database.
I have tried sys.dm_db_file_space_usage , but the documentation says that it only works for the TempDB.
Please help.

Hi, paws.
My server crashed recently, I didn't give to much importance because I knew that having access to the partitions I could recover my DB files and attach my database to my new server, and everything was fine until ... I found that my DTS Packages and Jobs where not in my Attached DB.
Now, where can I find these ?
Can you help a tormented man ?
Thanks in advance.

Anyone know of a good "free" way to back up web files and SQL Server 2005 Express Database?
I was able to use Windows Server 2003 Backup utility to back up the folder where the Databases were stored, as well as the web files, with no errors.
But I have heard a lot of discussion that you can't just simply backup SQL Server data files?
I'm wondering how sound the backup I've created is...
Any suggestions?
I created a new database in SQL Server 2000, using the command
"CREATE DATABASE ContactManager ON PRIMARY(NAME = ContactManager,FILENAME ='C:Program FilesMicrosoft SQL ServerMSSQLDataContactManager.mdf',SIZE = 5MB,MAXSIZE = 20MB,FILEGROWTH = 5MB)LOG ON(NAME = ContactManager,FILENAME = 'C:Program FilesMicrosoft SQL ServerMSSQLDataContactManager.ldf',SIZE = 2MB,MAXSIZE = 10MB,FILEGROWTH = 2MB)Go"
Databse was successfully created and I created two tables also in it. Now when i try to create a new connection in Visual Web Developer 2005, I get the error message :
"Directory lookup for the file "C:Program FilesMicrosoft SQL ServerMSSQLDataContactManager.mdf" failed with the operating system error 5 (Acess is denied.).
Cannot attatch the file "C:Program FilesMicrosoft SQL ServerMSSQLDataContactManager.mdf" as 'ContactManager'."
What else do I need to do use the database?
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?
Dear All,
I am making web application using Asp.net C#(Visual Studio2005). And Sql server 2000 as a back End.
Actually I am fetching data from other database(named as retailexcel but in same server). I have wriiten a view (in retailexcel database) to get required data from four table of other database. My problem is when I fetch those data(about 40000 to 50000 record) It taking to much time. I tried catch feature of asp.net2.0. Time reduced but not significantly. So I am trying to import those tables to my database (named Inventory) from that retailexcel.
Now problem is every day or two, record of those tables changes. How can I keep update my tables (which are importing from retailexcel)
Please suggest me some idea.
Thanks

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.

Hey!
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!

Can multiple instances of SQL 2005 Express attach to the same database files on a network share? I have seen this done before with MSDE where the database files are stored on the server, but instead of having a SQL server running on the network and then connecting to it, only the database files exist on the network share and the users connect through MSDE running on the local machine. Is this possible with SQL2005Express? I do not have the ability to share an SQL instance from one workstation to another nor do I have the ability to install an instance on the corporate server. Is it as simple as creating the database and storing the files on the share then attaching the database to the SQL Instance on each workstation?

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?

Hi All
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
