Bob Pusateri shows how to keep a dataset up to date using Powershell and dbatools:
Now for the magic – let’s load some data! The dbatools command that does all the heavy lifting here is called Import-DbaCsvToSql. It loads CSV files into a SQL Server table quickly and easily. As an added bonus, the entire import is within a transaction, so if an error occurs everything gets rolled back. I like to specify my tables and datatypes ahead of time, but if you want to load into a table that doesn’t exist yet, this script will create a table and do its best to guess the appropriate datatype. To use, simply point it at a CSV file and a SQL Server instance, database, and (optionally) a table. It will take care of the rest.
It’s a nice post covering one more method of automating data loads without a major amount of orchestration.
