USE FyiCenterData;
GO

SELECT * INTO fyi_links_copy 
   FROM fyi_links WHERE counts > 0;
GO

CREATE VIEW fyi_links_view AS
   SELECT * FROM fyi_links_copy;
GO

SELECT COUNT(*) FROM fyi_links_view;
GO
50015

DROP TABLE fyi_links_copy;
GO

SELECT COUNT(*) FROM fyi_links_view;
GO
Msg 208, Level 16, State 1, Line 1
Invalid object name 'fyi_links_copy'.
Msg 4413, Level 16, State 1, Line 1
