I don't often use SQL Server, but occasionally I need to replicate issues from databases in a local controlled environment.
Some of the databases I work with are rather large and can't be loaded into a GUI front end to import scripts. These scripts need to be loaded from CLI
sqlcmd -S 192.168.1.116,1433 -d WebApp -l 30 -U username -P password -C -i WebApp_202605281822.sql
