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.
The data, compiled by the Substance Abuse and Mental Health Services Administration (SAMHSA), also indicate that approximately 9.3 million adults, or about 4 percent of those Americans ages 18 and up, experience âserious mental illnessâ â that is, their condition impedes day-to-day activities, such as going to work.
