The following account permissions are required by SQL Prompt:

• For SQL Server 7 or SQL Server 2000, SQL Prompt requires administrative or dbo or Sys Admin permissions.
• For SQL Server 2005 you can use the same permissions as for SQL Server 7/2000 or alternatively you can use the GRANT VIEW DEFINITION TO [{username}] which provides SQL Prompt with permission to retrieve the metadata without giving dbo access.
• For SQL Server 2008 and SQL Server 2012, it may be necessary to grant VIEW SERVER STATE to access information about encryption keys otherwise a 'User does not have permission to perform this action' message may prevent the display of candidates.
