Oracle 12c sys.snap $视图不存在

Question

I am trying to run Redgate Schema compare tool, and I am getting the following errors:

SELECT s.sowner as owner, s.vname as mview_name, decode(bitand(s.flag, 262144), 262144, 'Y', 'N') as reduced_precisions 
FROM sys.snap$ s 
WHERE (s.sowner = 'OBSOLESCENCE_DATA_STORE' );
10:25:26.511|Error  |Object Model        |7  |Failed to execute reader
Devart.Data.Oracle.OracleException (0x80004005): ORA-00942: table or view does not exist

at Devart.Common.DbCommandBase.ExecuteDbDataReader(CommandBehavior behavior)
at Devart.Data.Oracle.OracleCommand.ExecuteReader()

I tried to query the view directly from sql developer, but with no luck. I'm assuming this isn't correct, but I have no idea how to fix it. Any help would be appreciated.

Answer 1

I know this question was asked sometime back. For all others benifit I would like to respond.

As per my knowledge these type of views can be accessed by sys user by default. Since the user doesn't have a DBA and if he is aware of how to logon as " sys as sysdba " then you should be able to access snap$ .

The alternate method is to ask the DBA to grant

GRANT SELECT on sys.snap$ to *[user logged in]*
