Linked server #Back to Basics

Really back to basic, but here is another example how to move data from one server to the other in a scheduled job.

First make sure, when you use an sql account to connect both servers, the account exist on both ends of the line.

Now we create a linked server, after all my former tutorials, I don’t have to go into detail, either script it or use SSMS gui, un this case I’m using it for a MSSQL to MSSQL this is easy peasy.

LS_make

Create a database and table if it doesn’t exsist on the server you want to insert the data in.

If all is setup, write a simple INSERT INTO script:

INSERT INTO [FunFactory_II].[dbo].[Accounts_NAWT]
(AccountNumber]
,[Name]
,[Street]
,[PostalCode])
SELECT
[AccountNumber]
,[Name]
,[Street]
,[PostalCode]
FROM [FunFactory_I].[dbo].[BSN].[Accounts]

And the last step is to create a job, to start the import automatically and schedule it to run on a given time.

This is my really #back to basic linked server tutorial, but you can add and tweak functions into the script and built fully automated solutions for your data.

For example a scheduled sql job to insert data from the linked server.

Linked server to Microsoft Azure #Error 405150

When Azure was launched, we missed one important feature, the linked server, It seemed impossible to do cross database queries from your local database to the Azure database, but Microsoft listened and made it possible to do database queries that spans multiple databases across platforms.

There is plenty of hits when googled on the errors, but none of these are complete! I will write down the  process of linking your server to Azure.

when I first created a linked server to Azure, I got this error  “reference to database and/or server name is not supported in this version error: 405150”, When trying to add a linked server from SSMS, you are not given option to set a default database. So I used Tsql instead, because without a specific catalog, your linked server will not work.LS_Azure

Azure doesn’t allow you to alter the master db, so you have to connect directly on the database you are going to use.

What people never tell LS newbies and make you google this error “Msg 2812, Level 16, State 62, Line 1 Could not find stored procedure ‘sp_addlinkedserver’ ” and read tons of blogs and tutorials all providing different queries, but still no work, follow these steps”.

The Tutorial, the Solution:

Open up ODBC, or simply run odbcad32.exe. and start by making a new system DNS with the Native client.

ls_SYSDNS

In the next step, you provide your datasource name and the complete server name as you can find on the Azure server.

LS_makedns

Also provide the database you want to connect to, don’t skip this one!

LS_Choosedb

 

Test the connection, see it succeed! if not, go through the above printscreens you probably missed a step.

LS_Testsuccesf

Now we can create the linked server on your database, by creating a query on your SSMS and can run your linked server query, it should look similar to this:

EXEC master.dbo.sp_addlinkedserver @server = N’Azure_server’, @srvproduct=N”, @provider=N’sqlncli’, @datasrc=N’t20ko02v18.database.windows.net’, @catalog=N’Teletraan IV’ EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N’Azure_server’, @useself=N’False’,@locallogin=NULL,@rmtuser=N’skyscream’,@rmtpassword=’password’

To test if the LS is added, you could run exec sp_helpserveror just test the connection.LS_SPhelpserver

These are all the steps to a Linked Azure server. Congratulations, you are now connected to the Azure mothership of data.

Data manipulation

Next step is to insert data from the Azure linked server into our local database. Btw, this query works both ways, you could also insert data into the Azure database.

Create an INSERT statement

BEGIN TRAN INSERT INTO [Azure_demo].[dbo].[Demo] (Initials,Prefix,LastName,Gender,Street,HouseNumber ,Zipcode,City,PhoneNumber,MobileNumber,EmailAddress) SELECT Initials,Prefix,LastName,Gender,Street,HouseNumber ,Zipcode,City,PhoneNumber,MobileNumber,EmailAddress FROM [Azure_server].[Teletraan IV].[dbo].[AzureData] WHERE InsertDate BETWEEN ‘2008-08-22 00:00:00.000’ AND ‘2009-02-06 00:00:00.000’ ROLLBACK TRAN –COMMIT TRAN

Now all rows have been added through our linked server into our local database. LS_Check

Create and Export a bacpac file to Azure Storage

Next in my Azure database series is the bacpac file, Azure works with bacpac files, we can up- and download to azure. We need a storagespace in order to up and download files.

We start creating storage space. This may come in handy when we need file tranfer, and again you can access the files from your local device.
1.storage

To acces your storage account, you need the access keys, which are generated when creating the storage account. On the footer of the page, where the red arrow is visible in the screenshot below, you can open up and acces the keys. 2.storage

This key you need for the net step, we will download a windows Azure storage explorer to be able to acces the files. Azure has a broad choise in downloads for this option. I downloaded the Azure storage explorer from codeplex storage explorer.

Now I will walk you through on how to create a bacpac file on your local database. Choose the Export Data-tier Applicationbacpac1

Now we have to options, you can create the bacpac file locally and upload it with the storage explorer or link it to azure directly, we choose tthe latter. Fill in the storage credentials we just created by connecting the storage account with the access keys. Name a container and filename and thunderbirds are GO!

Connect your Azure database from your local SSMS #Error 40615

Ofcourse we wanna access our fresh imported database on Azure locally!

And this is so easy if you just follow these simple steps.

In order to be able to access the database located on your Azure cloud, you have to know the Azure address, which you can find on the Windows Azure Management Portal. Click the database icon and open up the database. Here you will find the connectionstring.

azure_link

Next step is to make sure Azure knows your device by adding it to the trusted devices in Azure, if your device is unknow to Azure it will bring you the following message:1error-whenlocal_connection

you can add the device by going to the database icon in Azure and click the CONFIGURE tab. Here you add and save your device IP.2local_adTosavelist

Now you can login to your Azure cloud with the credentials you made while creating the database on Azure.

SQL database migration to Microsoft Azure with codeplex

sql-database-windows-azureThere are multiple ways to migrate your database to the Azure cloud. Today, I am testing this sql azure plugin by codeplex. I unzipped it to my local folder and run it as admin.

1.InstallAzurePlugin

Now fire up the SQLAzureMW.exe and the script wizard starts up, which is very intuitive, choose the available options, In my case, I will migrate from SQL database to Azure SQL Database. Fill in your database details and run the export. This might take a while depending on how big your SQL Database is. You can also make a selection of tables/views you want to export, or just export the whole database.

Azure1

Azure2 Azure3   Azure4 Azure5 Azure6   Azure7

Make sure you fill in the correct details for your target server (you can find your sql connection data on your azure Database configure page.) Azure10  Azure11

Now the database will be brought to the Azure cloud, again this might need some time, but you can see the progress on screen.

I’m a big fan of this sql azure plugin by codeplex , Like i said it’s very intuitive and gives you several options to work with your local and azure data.
