I am new to this forum and already searched for 45 minutes to find a solution for my problem. I hope you can help me.
A Gateway to a remote Microsoft SQL Database was installed on a Oracle Server (Oracle 12c). The tsnnames.ora file was appropiately set up.
For the connection, I created a database link (In the Oracle DB) as follows:
CREATE DATABASE LINK TEL CONNECT TO "fb_B2C" IDENTIFIED BY "passwort" USING 'dg1msql';
When I now execute the Select statement:
SELECT "name" FROM "sys"."databases"#TEL
it shows me the according databases. Among others, I can see the AB_Colors database.
Now, I want to select a view in the AB_Colors database.
Due to the fact I can connect to this database via Excel, I know that in the database AB_Colors, there are 10 Views(A,B,C,..). I would like to select the View C from the database AB_Colors via the DB LInk.
Owner of the View is b2b.
How do i need to formulate the select statement to do it?
I already tried different writings:
SELECT * FROM b2b.C#TEL;
SELECT * FROM "AB_colors"."b2b"."C"#TEL;
SELECT * FROM [AB_Colors].[b2b].[C]#TEL;
The common error message is: View/Table does not exist
I highly appreciate your help,
Fedja
This is the correct format
SELECT * FROM "b2b"."C"#TEL;
The issue maybe because the database you want to select from is not the one specified in the gateway for dg1msql. You can't add the database name to the query so you must specify it in the gateway connection.
This is defined in
$ORACLE_HOME/dg4msql/admin/initdg4msql.ora
where you should check HS_FDS_CONNECT_INFO

I have connected to a Datamart via SSMS. Behind the Datamart is an Azure SQL database.
I am trying to find out my username. I used the following query:
SELECT USER_NAME();
I get this error:
Unsupported sql function USER_NAME. Line:1, Position:8
I have combed the internet but I have not come across something that works yet.
in MS SQL SERVER you must use
SELECT CURRENT_USER;
The op wrote in the comment, that he needed to close the open query box and open a new one, after that it works, like a charme.
or to get the windows user mame of the logged in user
SELECT SUSER_NAME() LoggedInUser
I have created a linked server using SQL authentication and the connection seems to work as I can select from the master database.
However, I cannot select from a specific database to which the SQL account I use in the linked server has access.
I tried following the suggestions in other similar posts in here but to no avail. Any help really appreciated. I am attaching a screenshot of the security settings.
Thanks.
This is a bit of a long shot, but since no one else is answering so we'll give it a go. If you restored the DB from another server, it's possible the ssid's are out of whack. Switch context to the DB on the linked server and run the following.
EXEC sys.sp_change_users_login #Action = 'Report'
If any results show up with the login in question, remove it by running this.
EXECÂ sp_change_users_login #Action='update_one', #UserNamePattern='your_user',#LoginName='your_login';
I am new to using using stored procedure and Azure storage account. I am exploring the following guide at:
https://www.sqlshack.com/how-to-connect-and-perform-a-sql-server-database-restore-from-azure-blob-storage/
and have created a credential in my database 'Security' > 'Credential' folder in SSMS.
Query that I ran in SSMS:
--using the url and the key
CREATE CREDENTIAL [Credential_BLOB]
WITH IDENTITY= 'https://<account>.blob.core.windows.net/',
SECRET = '<storage account key -> which I enter my Access Key 1>';
Result:
After which I proceed to run the following stored procedure where I want to restore the backup from BLOB storage:
RESTORE DATABASE Database_Name FROM URL = 'https://<account>.blob.core.windows.net/Container/SampleDatabase.bak'
WITH CREDENTIAL = 'Credential_BLOB',
And I get this error:
Msg 41901, Level 16, State 2, Line 3
One or more of the options (credential) are not supported for this statement in SQL Database Managed Instance. Review the documentation for supported options.
However, from the guide which I input the link above, they were able to run the query:
I tried to google for the syntax of the RESTORE statement from the Microsoft Docs library and others who may have encountered similar issue but I did not find any effective result. I would appreciate your help if you have encountered something similar and would like to share your solution. Thank you!
From the error which you have shared, it is easy to interpret that you are using the SQL Database Managed Instance. But the link you have shared doesn't mention anywhere which SQL Server it is using. The approach mentioned in that link might not work in your case because of difference in SQL servers and statement compatibility.
Then, I tried the steps which are given in the Microsoft official document (link shared by #Nick.McDermaid in the comment section). It is working fine without any issue.
Please follow the steps below to achieve the requirement (applicable for SQL Server 2016 (13.x) and later, Azure SQL Managed Instance only).
Use the GUI in SQL Server Management Studio to create the credential by following the steps below.
Connect with your SQL Server 2016 (13.x) and later or Azure SQL Managed Instance
Right-click your database name, hover over Tasks and then select Back up to launch the Back Up Database wizard.
Select URL from the Back up to destination drop-down, and then select Add to launch the Select Backup Destination dialog box.
Select New container on the Select Backup Destination dialog box to launch the Connect to a Microsoft Subscription window.
Sign in to the Azure portal by selecting Sign In and then proceed through the sign-in process. Select your subscription from the drop-drown.
Select your storage account from the drop-down. Select the container you created already from the drop-down. Select Create Credential to generate your Shared Access Signature (SAS). Save this value as you'll need it for the restore.
I also tried to restore the database using the newly created credential and it is working fine.
To create the credential using T-SQL, please follow the steps provided in this link.
I am want to make the following statement:
INSERT INTO [Server_1\Instance_1].[Database].[dse].Table1
SELECT * FROM [Server_2\Instance_2].[Database].[dse].[**Table1**]
The point is the tables are on the different servers. I tried with the statement above. However, when I am on server_1 and when I run the following statement in order to retrieve the data from server 2:
SELECT * FROM [Server_2\Instance_2].[Database].[dse].[**Table1**]
... I get zero rows.
But when I run the statement above on the Server_2, I get a set of rows.
How can I transfer data from production to development server/environments?
I am using MS Management Studio.
UPDATE:
The error message I am getting when I run the select statement in order to retrieve the data from another (production) server:
The OLE DB provider "SQLNCLI10" for linked server "Prod_Server\Instance" does not contain the table ""Database"."dse"."BoxIteration"". The table either does not exist or the current user does not have permissions on that table.
Select statement is:
SELECT * FROM [Prod_Server\Instance].[Database].[dse].[BoxIteration]
Two things to take into account:
add the source server as a linked server in the destination server
verify that the credentials specified while creating the linked server have access to the data in the source server
I have a localized version of SQL Server, so the transalation may not match what you will see in your screen: open Object Explorer window in SSMS, connect to the destination server, open the tree and look for Server Objects, Linked Servers. Right click on the source linked server, and see the properties. Open the Security pane, and see which credentials are used to connect to the linked server.
Once you do so, you have to check the permissions of that credentials on the source server to verify that it can acccess the table in question.
If you don't understand, or can't do some of the steps (for lack of permissions), get help form your DBA: he will understand and solve the problem at once.
If u have access(Having credentials) to both prod and dev Db servers you can use "Import and Export Data"
1.Go to start and open "Import and Export Data"
Wizard will open give source server name, credentials and Database(For your case Prod)
Then give destination server name, credentials and Database(Dev)
Select the table , if there any identity column -->"Edit Mapping" and Enable identity insert.
Then give next--> it will start copying.
I have to include one report in my application showing offline/online activity of few databases on SQL Server 2008.
Could you please suggest how can I collect teh same information from sql server?
SELECT DATABASEPROPERTYEX('YOURDATABASE', 'Status')
DatabaseStatus_DATABASEPROPERTYEX
GO
SELECT state_desc DatabaseStatus_sysDatabase
FROM sys.databases
WHERE name = 'YOURDATABASE'
GO
This will tell you the status of the database.
In order to find out when your database was taken OFFLINE, you can use the SQL that I posted before, or the easiest way is to check the Event Viewer and it will tell you when the Database was taken OFFLINE. I have just tested this on my local machine and SQL Server writes out an Information message to the Application log.
You can also use below query to check database status.
SELECT Name, state_desc FROM sys.databases
