Deskripsi

The sa account is a widely known and often widely used SQL Server login with sysadmin privileges. The sa login is the original login created during installation and always has principal_id=1 and sid=0x01. Default: By default, the sa login name is 'sa'. 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.
