Bagaimana cara mengeksekusi file .sql menggunakan powershell?

Coba lihat apakah ada snap-in SQL:

get-pssnapin -Registered

Name        : SqlServerCmdletSnapin100
PSVersion   : 2.0
Description : This is a PowerShell snap-in that includes various SQL Server cmdlets.

Name        : SqlServerProviderSnapin100
PSVersion   : 2.0
Description : SQL Server Provider

Jika demikian

Add-PSSnapin SqlServerCmdletSnapin100 # here lives Invoke-SqlCmd
Add-PSSnapin SqlServerProviderSnapin100

maka Anda dapat melakukan sesuatu seperti ini:

invoke-sqlcmd -inputfile "c:\mysqlfile.sql" -serverinstance "servername\serverinstance" -database "mydatabase" # the parameter -database can be omitted based on what your sql script does.
