Hi,
Is there a simple way to verify if a database exists?
I'm writing a stored procedure that will accept a database name as an input
parameter,
and create the database if it does't already exist.

I need to write a stored procedure to verify that a table exists andalso that the user executing the stored procedure has access to thespecified table.Any user can call this publicly available procedure and pass a databasename, an owner name and a table name as parameters. The procedurereturns success if the table exists and the user has access to it, orfails if he doesn't. Here's a simplified version of what I have, butI'm wondering if there's a better way. Thanks.create procedure dumb asbegindeclare @myError int,@mytable varchar(128),@myquery varchar(128)select @mytable = '[Northwind].[dbo].[sysobjects2]'select @myquery = 'DECLARE @x int SELECT @x = count(1) from ' +@mytable + ' where 1 = 2'exec (@myquery)select @myError = @@ERRORif @myError != 0BEGINRAISERROR ('ERROR: The specified table %s cannot be accessed.', 10, 1,@mytable)RETURN 1endendgo

i have a table in witch i store the favorites pictures for each user, like so:
FavID PictureID UserId (uniqueidentifer)
users can add a picture at favorites by clicking a button from the picture table ("Add to favorites")
i need a stored procedure witch uses two input params (userId and PictureID), witch should return 1 if the relations between the PictureID and UserId already exists in the table(avoid having same relation again) or 0 if not (and i'll use that result to make the button enabled or disabled)
how can i do that?
if you didn't understood, please tell me
thanks
Hello, everyone:
Does any baby offer command to verify if database backup is completed? In backup wazard, there is an option "Verify backup upon completion" . Is there the SQL command? Thanks.

i want to verify these 2 statements on the tables in a particular database..
how can i do this..
I have a compact pc program that uses a sql server database (sdf file).
I want to check the database integrity when program starts so I added a call to veriy method of SqlCeEngine
string dbFullName = System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "NessDB.sdf";
SqlCeEngine engine = new SqlCeEngine("Data Source = " + dbFullName);
engine.Verify();
The call to verify always returning false and when I call repair
string dbFullName = System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "NessDB.sdf";
SqlCeEngine engine = new SqlCeEngine("Data Source = " + dbFullName);
engine.Repair(null, RepairOption.RecoverCorruptedRows);
the program crashes and I get an exception "The specified module could not be found"
Why this happen and how can I check database corruption.
Hi all,
I have taken more than one database backups and i have an idea that we can verify single backup using "restore verifyonly from disk='<path>'" statement.
Now my question is Could we verify all(More than one backup) backups with single statement?
Any suggestion would be helpful to me:-)
Thanks in advance,
I am looking for a Sql query to verify the inserted values from one table(in CSV file) with another table(in sql database)
For example: I have below Values column that is present in once CSV file, after my data migration the values get stored in Results table under Message column.
I need to very whether values(1X,1Y) are inserted in Message record "successfully inserted value 1X"
Values (CSV)
1X
1Y
Results Table(SQL)
CreatedDate                  Message
2015-08-04 08:45:29.203Â Â successfully inserted value 1X
2015-08-04 08:44:29.103Â Â TEst pass
2015-08-04 08:43:29.103Â Â successfully inserted value 1X
2015-08-04 08:42:29.203Â Â test point
2015-08-04 08:35:29.203Â Â successfully inserted value 1Y
2015-08-04 08:30:29.203Â Â Test Pass
2015-08-04 08:28:29.203Â Â successfully inserted value 1Y
If all values are inserted:
Output:
All values from values table are inserted successfully
Total count of values inserted: 2
If only few values are inserted, example only 1X from Values table is inserted in Message
Example:
Results Table CreatedDate    Message
2015-08-04 08:45:29.203Â Â successfully inserted value 1X
2015-08-04 08:44:29.103Â Â TEst pass

2015-08-04 08:42:29.203Â Â test point
Output:
All values from values are not inserted successfully in result table.

Missing Values not inserted in results table are: 1Y
Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.

Basically, I create a database with sql, then I delete it manually(not via sql statment. This is a problem which I realise. In fact, you can't delete the database because the VS 2005 still is using it) I run the same code again,
then it says the database still exists, even it is physically destroied.

Hi,
I'm wondering is there a command that I can use to check if a certain value exists in the database? Something that returns true or false perhaps?
SELECT * FROM Customers WHERE ID ='1'
Ok so that's simple, but how can I return a true or false if '1' is a value that exists in the db?
thanks.
I was able to get this code to work but now I get a SQL error if you try to submit the same information twice.

I have a table where I want to populate it with data (certain fields) from another table. But I only want to populate the table if there is data in a certain field in the table I wish to get the data from.
How exactly would I do this test? Would an I have to perform an IF statement to test if the field contains a value first?

I want to check to see if a database exists in SQL Server 2005 Express... using VB.NET (or C#)... Can not use the SQLConnection Object... because I get a Failed Login Attempt... regardless if the DB does not exist or if it is because the User Login is incorrect
Is there some way to check to see if the Database exists (is attached) to the SQL Server 2005 Express Engine?

I know allot of folks are having this problem and I tried lots of things but nothing works. I understand the problem is coping the SQL Express on another server is the problem - I just not sure what to do?
Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) +735091
I checked my server forum and they said I had to name a database:
Example: Database=(unique name);
But this didn't work either.
I just tried a simple web project that has only one database and one table in SQL Express with one sqldatasource and one datagrid. It works fine on my pc but when I use the copy function in Visio Studio 2005 Pro - I can't run the site on the remote server: www.myjewelrydirect.com
I tried coping the database manually. I tried disconnecting the database before I copy it. Below is my connection statement:
<connectionStrings>
<add name="TestDB" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|TestDatabase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
With all the comments in these forums - this must be a bug.
I have been working on this problem for over 2 weeks - HELP!
hi. i'm building a news section for some friends of mine. i list all the news items on the main page in a gridview. i've made a custom edit linkbutton that sends the user to an edit page, passing the news id as a quarystring variable. on the edit page i first check if the querystring variable contains an id at all. if not, i redirect the user to the main page. if an id is passed with the querystring, i fetch the matching news item from the database and place it in a formview control for editing.so far, so good. but what if someone types a random id in the querystring? then the formview won't show up and i'd look like a fool. :) therefore, i need some kind of check to see if the id exists in the database. if not redirect the user back to the main page... so i started thinking: i could check the databsae in a page_load procedure. if all is well, then display the news item. since the formview is automatically filled with the correct data, does that mean that i call the database two times? i mean, one for checking if the news item exists, and one for filling the formview. logically, this would be a waste of resources.help is appreciated.

I've restored a backup from server A in server B. In server A I used to have a db_owner, called sitebase. After restoring the backup in server B, I created the user sitebase again and tried to grant him db_owner through Server Manager but I got the error: user or role already exists in the current database.
How can I avoid this situation and grant db_owner to him?

Hi,
I'm using SQL Server 2005, and I would like to understand how to create and to drop a database without errors:
Infact, if I try to create a database that already exists, SQL Server throws the error "Impossible to create the database because it already exists", and if I try to drop a database that doesn't exist, SQL Server throws the error "Impossible to drop the database because it doesn't esist".
Before creating or dropping a database, I should control if it exists or not...
Is there a method to do that?
I found that such control for a table is the following one (in this case, I drop the table only if it exists):
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Table1]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[Table1]
I tried to adapt the statement to the database case, modifying it as follows:
if exists (select * from dbo.sysobjects where id = object_id(N'[Database1]') and OBJECTPROPERTY(id, N'IsDatabase') = 1)
drop database [Database1]
but it didn't function (it was a blind attempt).
Can you suggest me a statement to do that?
Thank you very much

However when I tried to access the test DB via Peoplesoft application, I am unable to logon. Only then did I notice that all the users, with the exception of "sa", were gone.

Hello everyone,
I have been playing with a Standard Version of VS 2005 and SSE 2005 and I just cannot get these two to interact together well. I am sure it is a noob problem but I have seen this error addressed on this forum and I am just not getting it. Here is exactly what I am doing.
I want to create a database within SSE using the Management Studio. Then, I want to connect to it with VS2005. Both SSE and VS2005 are local. I just cant seem to get this to work.
I always seem to get this error "An attempt to attach an auto-named database for file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataSecond.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
One thing... I create the website with Location: HTTP. I don't even know anymore why I do this.. I think because I like to be able to pull up a browser and get to my app. Other than that I am doing nothing special. However, I get the above error when I hit F5 to run the app inside VS2005.
Is there someplace where a complete noob can find a thorough and simple covering of this? Again, I have read through some of the previous posts on this and I don't understand too many of them and it seems as if there are at least 13 causes of which I don't know which one I have. Help!
Thanks.
Is there a way to find active connection to a database so you don't have to wait for a restore or similar operation to fail. (Which take forever).?
Is there a SMO method or a transact SQL command or something that can be used in an application to detect active connections?
I don't want to have to wait forever to get a failure when you can't perform a operation that require that there be no active connection such detach a database. I want to be able to tell when I can perform a operation which requires no active connection and when I need to use a task without out dropping the connection like copying the schema using SMO methods.
However if there are no connection I can perform a detach copy and attach to create a new database which is considerable faster.
i have database which has 25 tables. all tables have productid column. i need to find total records for product id = 20003 from all the tables in database.

Good Afternoon.
I am trying to write a short application within which I would like to embed a SQL Server Express database, all of which would be deployed via ClickOnce through a web site. The installation process seems to be working without trouble, including installation of the .NET Framework 2.0 and SQL Server Express 2005.
When the application launches on the new machine, however, I get a big Microsoft .NET Framework "Unhandled exception" error dialog box that indicates the database already exists and that the database file could not be attached. I am working with a clean virtual machine that I know has never had the database installed on it.
I fear I am overlooking something quite straightforward, but since this is the first time I have ever attempted to build a data-bound application, I am not sure where I am going wrong.
Perhaps the source of the problem, or a related problem, might be revealed even when I run the application in debug mode from within Visual Studio. I can run the application once, but if I try to run it again, I get an error when I try to open the database connection that is similar in content (database already exists...could not attach). I can run the SSEUtil and detach the database and then run the application again in debug mode and it works no problem (the first time!).
Lastly, if I install the application on the machine on which it was developed and make sure the database is detached, it will run without any trouble (even repeatedly). But, on a new blank machine, there is no database listed that matches my database name, so I cannot try to detach anything!?
My apologies for such a novice question!

Hi, all!
I'm really confused about how to run a query on the database to check to see the CustomerID filed value already exists in the database.
If it’s true, I want to display a message: “Valid� the user to proceed with the next steps

I tried all sorts of things and I just can't get it to do it. Hopefully you can help. Thank you
I cannot find any OLE DB reference material for how to perform a "Verify" DB as advertised in the Documentation for SQL Server Mobile Edition.
The docs have a sample in C#, but nothing for OLD DB in C++.
Does anyone know how to do this?
