I am trying to create a free SQL Database in Azure under my DreamSpark subscription but I repeatedly receive the following error:
When you start an SQL Database creation, Azure lets you choose or create an SQL Server:
Since I don't currently have an Azure SQL Server I have to create one. I figured my error could be isolated to the server creation and effectively, while trying to create only the server, the error still rises.
I think that, even if Dreamspark subscription allows for a free small SQL Database, it does not allow for a free SQL Server. But this does not make any sense because I think there is no way to have an SQL Database without an SQL Server... So my questions:
Could you please confirm or refute my suspicion about Azure not permitting a free SQL Server in DreamSpark subscription?
In case it is not allowed, is there a way to create an SQL database without an SQL Server in Azure?
In case it is indeed allowed, why do I have this error then?
Thanks in advance.
I ended up circumventing this problem by using visual studio 2017 to create DB and DB Server for me. So we can be sure that DreamSpark subscription allows for a small DB AND a DB Server creation, which makes sense.
Still, don't know why I was getting that weird error though.
While creating the db, visual studio changed the name I provided by concatenating "dbserver" and "_db" to the server and db respectively. Perhaps, there was a naming issue that VS solved automatically, and that Azure is not reporting correctly.

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'm having what I hope is a simple problem.
I've published an API to an Azure Web App, which should fetch data from an Azure SQL database, but I'm getting a 500 error, which of course isn't helpful. Checking the logs in Azure doesn't give anything more useful to me.
I've added the connection string to the connection strings in the Web App. I have also created a method which returns the connection string from the repository class that's using it, so I know it's definitely seeing the correct connection string; so this means it's an issue connecting to the database with that connection string.
I have ensured that 'Allow access to Azure Services' is switched on, and when I use the query editor I can successfully pull data from the database.
I've also connected to the database using SQL management studio so I know the database can be reached.
What am I doing wrong?
As usual it turns out to be my stupidity, but I'll answer here in case it helps someone else...
I just updated my local app to use the Azure db connection string so I could get a more detailed error and it said the keyword was not supported 'initial catalog'.
This is when I realised that I developed this locally using Postgresql but couldn't justify the costs of that on Azure so switched to Sql Server but didn't change my connections to SqlConnection types!
hi i have create 1 database in Azure SQL server .Now i want to create procedure using link server.And my other database is on different server not on Azure.So it is giving error .Please help
Linked servers are not supported in Sql Azure. If both servers were in Azure, you could used elastic database query to do cross database queries within the SQL Azure Server.
Perhaps you could give us a clearer idea of exactly what you're trying to do, and what the exact error is?
Scenario: I have a server farm to deploy my web site. I want to try to add one server from Azure platform. Every host has a replication from one database server. I have tried to add the replication database but I got this message error:
Microsoft SQL Server Management Studio is unable to access replication
components because replication is not installed on this instance of
SQL Server. For information about installing replication, see the
topic Installing Replication in SQL Server Books Online. (New
Subscription Wizard)
After this message I suppose that something is missing in the sqlserver database Azure side.
I have googled something to solve my problem but without luck.
I have found one tool (Azure SQL Data Sync) and tried something to solve the problem but it didn't work.
From the Azure documentation, I have found that until V12 of the azure database replication wasn't available.
But what about v12?
Questions:Am I missing something with the version of the database? Should I change the database plan in Azure subscription?
Should I use some external tool that allow me to maintain sync my database server with the replication?
Replication is not yet available according to the MSDN even on V12. You can use https://azure.microsoft.com/en-us/documentation/articles/data-factory-introduction/ and https://azure.microsoft.com/en-us/documentation/articles/sql-database-get-started-sql-data-sync/. You can write your own sync logic with change tracking, Service broker and linked servers / safe CLR but better use the existing tools.
Maybe Azure Data Factory Service could be a solution for you?

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.
