ups!! pasted from my batch directly:)...actually only first line is sufficient:

@for %%s in (output\sql\*.sql) do ( sqlcmd -S server-name -d database-name -U user-name -P password -i "%%s" )

😉

Create batch file with the following contents and replace

server-name, database-name, user-name and password.

@for %%s in (output\sql\*.sql) do ( sqlcmd -S server-name -d database-name -U user-name -P password -i "%%s"...
