Recently I was informed that Azure SQL V12 now supports
databases that use encryption. I have tried all methods documented here,
https://azure.microsoft.com/en-us/documentation/articles/sql-database-migrate-ssms/
When attempting to migrate a database I get these kind of errors:
[dbo].[someitem] cannot be deployed as the script body is encrypted
Here is a recent response from an Azure AMA,
https://www.reddit.com/r/AZURE/comments/3o1ea9/ama_azure_app_service_team_109/cvu7xco
what am I doing wrong to get this feature working? As I believe I have performed all the steps as documented.
Azure SQL Database V12 supports two types of encryption:
Transparent Data Encryption as documented here: https://msdn.microsoft.com/en-us/library/dn948096.aspx.
Cell Level Encryption: https://msdn.microsoft.com/library/ms179331.aspx and http://blogs.msdn.com/b/sqlsecurity/archive/2015/05/12/recommendations-for-using-cell-level-encryption-in-azure-sql-database.aspx
Which of these are you trying to use?
Do you need to migrate the database between 2 different Azure SQL DB servers or between an on premise SQL Server and Azure SQL DB?
Between 2 Azure SQL DB servers, you can do a true backup restore via CREATE DATABASE ... AS COPY OF... syntax (https://msdn.microsoft.com/en-us/library/dn268335.aspx). This works because the key is in the database backup.
Between SQL Server and Azure SQL DB, there is no term plan to support moving of encrypted procedures or views.
If you could elaborate why you are encrypting procedures and views, that would help us understand the problems you are trying to solve. Many of the scenarios we've encountered in the past where customers desired procedure and view encryption with SQL Server don't apply to Azure SQL Database, but we're always learning of new challenges people have protecting their databases.

Is it possible for me to insert some data from one database to another in Azure sql?
Let's say I have a trigger in db1 that updates some values in db2.
I read about elastic queries but it seems like they are read-only so they don't solve my problem.
You can't use cross-database in Azure Sql Server because databases can't see eachother physically , you could use elastic pools but they are Read Only.
A solution is to use SQL Managed Instance to upload your instance . This supports cross-database queries but it was expensive.
There was some previous discussion here about doing similar:
C# Azure Function trigger when SQL Database has a new row added without polling
There is also the Azure SQL Bindings for Azure Functions but they are input bindings and not triggers and they're still in preview and limited to C#, JavaScript and Python.

There was a new announcement last week after MS Build however for Azure SQL Database External REST Endpoints Integration (hopefully they don't refer to it as ASDEREI) but this is currently in preview under Early Adoption Program (EAP).

I would like to know what extra benefits one get by choosing Azure SQL Managed Instance compared to Azure SQL DB PaaS. I know SQL Managed Instance is offered as a vCore based purchasing model only. Apart from this what is the extra add on and benefits that one gets over the other. Any reply would be appreciated.
With Azure SQL Managed Instance, you essentially get a full fledged SQL Server that you can control any way you want, just like you would control a locally configured SQL Server. All the power and access and customization you want.
With, Azure SQL DB PaaS, you are essentially getting a database service, so, you give up a lot of control.
For example, take server collation. With the database service, SQL_Latin1_General_CP1_CI_AS , is all you get. With the Managed Instance, its your server. So, go ahead and select whatever collation you want, just like how you would select the collation at the time of creatoin.
Another issue is with auditing, if that is something that is important to your setup. with SQL Managed Instance, auditing happens at server level, because, you are getting the full database server. With the database service, it only database, because, you are only getting a database.
These are just the main details that I found. more details here at this Azure doc - https://learn.microsoft.com/en-us/azure/azure-sql/database/features-comparison
Of course, Managed is going to cost you more because you are paying for the license of the SQL server too.
Lastly, for me, this is the almost (not the exact same thing) like you running your own File Server on a Windows VM on Azure (Managed Instance) versus, just using Blob Storage. In both cases, you are just trying to store some files, but its how much control you have.
I would say think about Azure SQL DB vs Azure SQL Managed Instance (MI) as
Azure SQL DB = Resources dedicated to individual DBs like a container. They are grouped under a Azure SQL Server but that SQL Server is just for grouping.
Azure SQL MI = Almost same as on-prem SQL Server except you don't have to worry about OS, backups, high availability.
Here is a good comparison.

Hopefully this will help
Azure SQL Database - The usual PaaS way. You have vCore, DTU, and Serverless billing mode. And Elastic pool support.
Azure SQL Managed Instance - Similar as below. When you want to use instance-scoped features of Azure SQL Managed Instance like Service Broker, CLR, SQL Server Agent, and Linked servers. As if you have an SQL Server on premise, Azure is responsible for patching, upgrading version etc.
SQL Server on Azure Virtual Machines - Similar as above. But you are responsible for OS and SQL server upgrade.
I created an SQL database using ASP.NET Core 1.1 Migrations.
After I created the database I added some data to the database.
What options do I have to upload this database to Azure?
I need to send the Scheme and the initial data.
Is it possible to run Entity Framework migrations on Azure?
This article describes the possibilities to migrate an existing database to SQL Azure.
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-cloud-migrate
However, in your scenario, this might be overkill to go through the steps of realy doing a migration.
If your number of tables and data is rather small, why not create a SQL script to create the tables & insert the data?
Connect to your SQL Azure using SQL Server Management Studio and execute the script.
As for the Entity Framework, yes, you can run those on SQL Azure as well.
I need to migrate my mysql 5.6 DB to sql server.
Trying to decide wether I should use Azure "SQL Database" as an instance, or should I create a VM with SQL SERVER installed.
This is the SQL database I can create using azure services:
Or use one of these virtual machines:
any tips ?
Azure SQL would save you from the hassle of managing everything by yourself compared to the IaaS, SQL Server VM. However, this comes with tradeoffs like size limitation, sharding limitations etc. I think you'd appreciate a table comparison of the two to decide. Kindly find below article for a comparison of the two in terms of both business motivation and limitations.
Hope this helps!

My website is a .net 4.5 mvc site built with VS 2012. I have a SQL Server Compact DB in my app_data folder. All works great on my localhost. I deploy to Azure website and get this error?
Unable to find the requested .Net Framework Data Provider. It may not be installed.
I've googled it and get lots of possible answers, but none specific to Azure and SQL server compact. So my question is simple. Does a windows Azure Website which is deployed to an Azure shared hosting server support SQL Server Compact? If so, what do I need to do to eliminate the aforementioned error and make it work?
It certainly is possible to use SQL Server Compact on Windows Azure. However, you need to ask yourself:
Will I change anything in database?
This includes adding, updating and removing data. If you do, you should not use SQL Server Compact on Windows Azure. Because, if you use SQL Server Compact on Windows Azure and change anything in the database, you'll run into two problems:
Data is not replicated.
You risk losing data.
Data is not replicated
If you change anything in the database, the changes stays local. This means that if you have multiple instances running your web application, then each web application will have their own database, and if you change something in one of them, the change won't be replicated to other instances, which will result in unpredictable behaviour in your application.
You risk losing data
If you change anything in the database after deployment, you risk losing data, because Windows Azure might decide to redeploy your instance to another virtual or physical machine. When this happens, the new instance will be setup with the deployment package you originally uploaded to Windows Azure, and this package does not contain any changes you make to the database. And this redeployment can happen at any time for several reasons.
Conclusion
So, SQL Compact on Azure? Sure, no problem if your data is read-only. However, note that you won't get the performance you would with SQL Azure. But if your need changes down the road, you can always migrate your application from SQL Server Compact to SQL Azure.
If you want to use SQL Server Compact with Windows Azure, you can use the "private deployment" method, as explained on "ErikEJ"'s blog.
Edit: Microsoft has announced that they now provide 1 free 20 MB SQL Azure Database for every Azure subscription. This means you can create a subscription and create a free website, with a free SQL Azure Database. (As long as it's less than 20 MB) You can also have multiple Web Sites associated with the same SQL Azure Database for free. So, if you're considering SQL Server Compact on Windows Azure because your database will be very small and you don't want to pay for a 100 MB database, you can consider this option. In most cases, it will be a better solution. Your website will perform better, your database performance will be better and you have the ability to change your data and it will be replicated.
It's possible for SQL Server Compact 4.0 on Azure!!
I write an an article for it
And this is the English version I found
By few step:
Below is the solution after my research:
Step by Step like this:
Install two nuget: EntityFrame.SqlServerCompact & Microsoft SQL Server Compact Edition
put your SQL database file(.sdf/.mdf) in APP_Data folder
(Put the connection string like this in order to use it:
<add name ="DefaultConnection" connectionString ="Data Source=|DataDirectory|CompactDB.sdf" providerName ="System.Data.SqlServerCe.4.0" />)
Publish full project include above SQL database file to AzureWebsites.
you can find it can work well and is totally free.
Second Wenchao Zeng of Microsoft the Azure don't support Sql Compact.
I could use once but this is not recommended because the Windows Azure work with replication of the data (this is the cloud, remember?) and the Sql CE does not support this functionality. If you can to put a Sql CE in Azure sometimes will not get access or users see data outdated or broken because the async.
The best way is you to use the Azure Sql ou BLOB storage.
