23.15. The INFORMATION_SCHEMA VIEWS Table

The VIEWS table provides information about views in databases. You must have the SHOW VIEW privilege to access this table.

INFORMATION_SCHEMA Name SHOW Name Remarks
TABLE_CATALOG   NULL
TABLE_SCHEMA    
TABLE_NAME    
VIEW_DEFINITION    
CHECK_OPTION    
IS_UPDATABLE    
DEFINER    
SECURITY_TYPE    

Notes:

  • The VIEW_DEFINITION column has most of what you see in the Create Table field that SHOW CREATE VIEW produces. Skip the words before SELECT and skip the words WITH CHECK OPTION. Suppose that the original statement was:

    CREATE VIEW v AS
      SELECT s2,s1 FROM t
      WHERE s1 > 5
      ORDER BY s1
      WITH CHECK OPTION;
    

    Then the view definition looks like this:

    SELECT s2,s1 FROM t WHERE s1 > 5 ORDER BY s1
    
  • The CHECK_OPTION column always has a value of NONE.

  • The IS_UPDATABLE column is YES if the view is updatable, NO if the view is not updatable.

  • The DEFINER column indicates who defined the view. SECURITY_TYPE has a value of DEFINER or INVOKER.
