Hi @AmyKernow ,
Please check whether you have downloaded and installed sql server 2012. If you download it, there will be a sample database. Have you restored the sample database to instance? If not, please refer to the link below to restore:
AdventureWorks sample databases
Normally, Microsoft officially does not support sql server 2012, so it is not possible to download sql server 2012. If you must use the 2012 version, it is recommended that you find your boss to install the package.
If it is early learning, it is recommended to use the latest version of SQL server (sql server2019). Each new version of sql server just made some improvements on the basis of the old version, or added some functions, the basic sql syntax is the same. So which version you learn will not affect your later work.
In addition, the official Microsoft documentation is a good learning material, it contains a detailed introduction and examples of tsql, you can practice through the adventureworks database.(A few examples may not run successfully in sql server2012)
E.g:FROM clause plus JOIN, APPLY, PIVOT (Transact-SQL)
Finally,involving database installation and operation issues, I suggest you open a thread in Azure SQL database forums, i
People there will help you more effectively.Hope this could help you.
If you have any question, please feel free to let me know.
