如何从 SQL 上的现有表在数据块中创建表

Question

Can someone let me know how to create a table in Azure Databricks from a table that exists on Azure sql server? (assuming Databricks already has a jdbc connection to the sql server).

For example, the following will create a table if it doesn't exist from a location in my datalake.

CREATE TABLE IF NOT EXISTS newDB.MyTable USING delta LOCATION
'/mnt/dblake/BASE/Public/Adventureworks/delta/SalesLT.Product/'

I would like do the same but with the table existing on SQL Server?

Here is the basic solution for creation of an external table over an Azure SQL table
You can take the url (connection string) from the Azure Portal

create table if not exists mydb.mytable
using jdbc
options (url = 'jdbc:sqlserver://mysqlserver.database.windows.net:1433;database=mydb;user=myuser;password=mypassword;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;', dbtable = 'dbo.mytable')
