Ensure no login exists with the name 'sa'

中等級 1自動化mssql

說明

The sa login (e.g. principal) is a widely known and often widely used SQL Server account. Therefore, there should not be a login called sa even when the original sa login (principal_id = 1) has been renamed. Default: The login with principal_id = 1 is named sa by default. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.
