One basic concept to understand about SQL Server is that of catalog views, which are effectively database tables (catalogs in this case) that display system-wide information about the SQL Server Database Engine. All catalog views are accessed via a SELECT SQL statement FROM a specific catalog within the sys. namespace. For example, the following statement can be used to view information about all database tables in the system via the sys.tables catalog: SELECT * FROM sys.tables.
Mental disorders were one of the five most costly conditions in the United States in 2006, with expenditures at $57.5 billion. Over 8.9 million persons have co-occurring disorders â that is, they have both a mental and substance use disorder.
Although fewer than 6 percent of American adults will have a severe mental illness in a given year, according to a 2005 study, many moreâmore than a quarter each yearâwill have some diagnosable mental disorder. Thatâs a lot of people. Almost 50 percent of Americans (46.4 percent to be exact) will have a diagnosable mental illness in their lifetimes, based on the previous edition, the DSM-IV. And the new manual will likely make it even easier to get a diagnosis.
