Lnked server in sql azure db - azure

I have read many articles but i cannot be confirmed if linked server is supported in SQL Azure DB(PAAS)environment? I read somewhere that it is applicable only in hybrid environments.
Can anyone please confirm if linked server can be used with databases in azure and not just in hybrid?

Linked server are not supported in SQL Azure; you can only create a linked server in an on-premise SQL Server to a SQL Azure database.

Azure database file location

There is Azure SQL server with name xxxdb10.database.windows.net that is up and running. I am trying to create DB there and I have to use specifics application in order to have proper DB structure. Everything works with SQL Server Express as you can see below, program add file location automatically. But when I try to point to Azure SQL server and do the same application does not recognizance path and I got this error below. What to use for database file location in case of Azure SQL server please, can you help?
With SQL Server Express:
With Azure SQL server:
• I would suggest you use Microsoft SSMS (SQL Server Management Studio) tool to connect to the Azure SQL Server created in Azure instead of SQL Express. Since SSMS is only a tool for managing various types of SQL Databases locally or in Azure, thus it should be promptly used for creating such Azure databases. Please refer the link below on detailed documentation and information regarding this as well as refer to the snapshots depicting the usage of SSMS as a prompt tool for connecting to Azure SQL databases and server.
https://learn.microsoft.com/en-us/azure/azure-sql/database/connect-query-ssms
In the above snapshots, you can see that we can connect to an Azure SQL Server and creating a database in it through SSMS.

Migrating SAP Sybase ASE to AZURE

Im new to the cloud universe of Microsoft and confused with their Migration Services, so forgive me if this question seems like there was no effort put into finding an answer myself.
Im evaluating to migratre our Sybase ASE 16 environment to the Cloud, preferably to AZURE, because of Sybase and Microsoft both rely on T-SQL for procedural programming. This being said I was looking through the docs and could not find any out of the box cloud migrating solution for Sybase.
Link:
https://learn.microsoft.com/de-de/azure/dms/resource-scenario-status
I understand Microsofts definitions of offline and online migration but neither offer a service for Sybase products. I then stumbled up on SSMA ( Micrsoft SQL Server Migration Assistant for SAP Sybase ASE). From my understanding this is a tool to migrate a Sybase Database to a Microsoft SQL Server Database and has nothing to with AZURE.
But I could have an AZURE DB sitting in the cloud and just use it as the destination for my migration?
Is this best practice for SAP Sybase ASE migrations to AZURE?
Azure offers a migration tool to migrate to the cloud. If you need to migrate a Sybase Database you will need to use Microsoft SQL Server Migration Assistant for SAP.
In order to migrate your Sybase Database you need to download the SSMA Client and the extension pack for your Microsoft SQL Server.
Inside the SSMA you first have to convert selected database schemas, then synchronize them in the bottom database explorer with your destination database and then you are ready to hit the migration button.
Keep in mind that Microsoft SQL Server is case insensitive by default but you can change the case sensivity on a database level for sysdb in Microsoft SQL Server Manager.
Also it is important to point out that this tool only migrates DDL but not users and permissions.

Difference between Azure database for MySQL and Azure SQL database

I am learning azure from Microsoft learn using this link. Does anyone know the basic difference between "Azure Database for MySQL" and "Azure SQL Database"? Both seem very similar.
As I am a beginner, can anyone explain the difference in an easy way?
Add to #CoderRambo's answer. The difference between Azure Database for MySQL and Azure SQL Database is as follows:
Azure Database for MySQL is powered by the MySQL community edition. We can choose versions 5.6, 5.7, and 8.0.
Azure SQL Database is SQL Server database engine, based on the latest stable Enterprise Edition of SQL Server.
The only similarity is: they are all hosted in the Microsoft cloud and fall into the industry category of Platform-as-a-Service (PaaS). So your question is mysql vs sql server.
ok lets start with what is common for both. with Azure prefixed, both are installed in cloud and managed by Microsoft. Meaning Microsoft is responsible for the databases to be installed, up and running with 0 or minimal downtime. I think this is clear.
Now lets start with differences. Please visit the links below and let me know if you have any issues. Thanks!
https://www.guru99.com/sql-vs-mysql.html
https://www.javatpoint.com/mysql-vs-sql
Mysql is opensource database, where as when you say SQL it refers to Microsoft SQL Server.
In general both are two different types of databases. Microsoft SQL Server is a licensed version.
When you prefix them with Azure, it means they are hosted on cloud , i.e Azure cloud and Microsoft manages them as PAAS(platform as a service).
Kindly let me know if you need more information.

Is it possible to attach a MDF file to an Azure SQL database?

I have just created an Azure Website and Linked SQL Database.
I have a SQL Server 2008 SP2 database on my local machine. Is it possible to detach the local .mdf file, FTP it to Azure and then attach it as a SQL database in Azure? The only other way is to export the scheme and load this, followed by the data.
In the absence of detaching and attaching DBs, I have come across "SQLAzureMW" which looks very useful in guiding me through this process.
Thank you in advance.
You can deploy an database from Management studio to Azure.

Migrating from "SQL Server" to "SQL Azure, while already using "Linq to SQL"

I want to migrate an existing application from SQL Server to to SQL Azure. I am using "Linq to SQL". The application is local, what i assume is that i will only have to change the connection string and the application will be connected to the cloud instead of local database and no change is required at code level.
If you already have your database migrated to SQL Azure, then yes all you will need to do is change the connection string and open the SQL Azrure firewall to allow your clients to access the DB (this you can do in the portal).
However, while SQL Azure is very close to SQL Server, it isn't exactly the same. Lots of links to official variations can be found in this article or you can try running the SQL Azure Migration Wizard
