I am trying to migrate my on premise SQL Server views which has fewer joins to extract the output. I have extracted the views ddl through generate script but when ran it on Azure Synapse it's not working please help

A client of mine needs to join tables from his Azure SQL financial data mart with external tables built upon a Data Lakehouse (Parquet files) in Azure Synapse Analytics.
I was wondering if it's possible to create a database link within a Azure SQL database accessing a Azure Synapse Analytics Serverless (on-demand) SQL Pool.
Yes, it’s possible open the Integrate hub, and select and add a link connection.
Select test connection and make sure to check whether SQL firewall rules are properly configured or not.

We are looking at options for moving our on premise SQL Server(s) to Azure and trying to understand whether we will be able to run cross database queries should we have data residing across multiple database technologies both in Azure ( specifically Azure Managed Instance, Azure Synapse Analytics, Azure SQL Database), and in an on-premise SQL Server instance.
We cannot find much information anywhere on whether these are supported and would appreciate if any of ye could help in filling out the table below:
TO->
Azure SQL DB
Azure Managed Instance
Azure Synapse Analytics
On Premise SQL Server
Azure SQL DB
Supported through Elastic Search Query (Ref: https://azure.microsoft.com/en-us/blog/querying-remote-databases-in-azure-sql-db/)
?
Azure Data Share supports sharing of both tables and views from Azure SQL Database and Azure Synapse Analytics (formerly Azure SQL DW), and sharing of tables from Azure Synapse Analytics (workspace) dedicated SQL pool. Sharing from Azure Synapse Analytics (workspace) serverless SQL pool is not currently supported. (Ref: https://learn.microsoft.com/en-us/azure/data-share/how-to-share-from-sql)
Azure SQL database doesn't support the linked server property so you wont be able to access on prem tables in Azure SQL database and the elastic query in Azure SQL database is to query tables between 2 Azure SQL databases and not On prem. (Ref: https://learn.microsoft.com/en-us/answers/questions/289105/how-can-i-query-on-premise-sql-server-database-fro.html)
Azure Managed Instance
?
?
?
Available through the use of Linked Servers (Ref: http://thewindowsupdate.com/2019/03/22/lesson-learned-81-how-to-create-a-linked-server-from-azure-sql-managed-instance-to-sql-server-onpremise-or-azure-vm/)
Azure Synapse Analytics

Using a linked server you can query data in an Azure SQL database from an on premised SQL Server (Ref: https://learn.microsoft.com/en-us/answers/questions/289105/how-can-i-query-on-premise-sql-server-database-fro.html)
Azure SQL database need elastic query to achieve cross database query. It doesn't support create linked server.
Azure Managed instance has almost same feature with on-premise SQL server, you could use USE statement to execute cross database query. It's same with local SQL Server.
Azure Synapse Analytics also doesn't support cross database query.
Per my knowledge and experiense, I will put ✔ or X in table to express support or not supported. please ref:

Please choose the suitable Azure database version according your request.
HTH.
AFAIK there is no cross-DB facade that provides a single interface to talk to multiple Databases at the same time. Be it on-prem/in-cloud or SQL-Server/Synapse/MySQL/...
There are individual ways and means by which you can access a single Database from somewhere/anywhere. E.g. accessing an on-prem DB from code in cloud or access a cloud DB from code running on on-prem "servers". List of interfaces available is specific to each "source" and "target" combination.
I have a project that is running on a local SQLExpress server. I have exported my database to a .bacpac file.
I am trying to restore that DB to an Azure SQL server. So what I am trying to do is to create a DB on Azure using this back-up file.
How can I do that?
The easiest way to migrate a database to Azure SQL Database is using Data Migration Assistant (DMA). This tool performs an assessment first to verify the database does not use incompatible statements with Azure SQL Database, and it also migrate the schema and/or the data, as you wish. Download it from here.
I imported it through SSMS by connecting to my Azure SQL server and doing import data-tier application
I'm doing some tests with Azure Data Lake Analytics and I can’t add a new SQL Server database as a Data Source. When I click on "Add data source", the only two available options are: "Azure Data Lake Storage Gen1" and "Azure Storage".
What I want is to add one SQL Server database so that I can run U-SQL queries against it.
Our SQL Server firewall is correctly configured to allow access to Azure Services, but I am not allowed to add it as a data source.
How can this be done? Is it a matter of other configuration issues?
Any help would be greatly appreciated.
Per my research ,there is no other configuration issues for sql server data source in DLA. Based on this official doc, DLA only supports two data sources:Data Lake Store and Azure Storage.
As workaround , I suggest you using Azure Data Factory to transfer data from sql server database to azure storage so that you could run U-SQL script against data source.
Any concern,please let me know.
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.
