SQL - ALTER SECURITY POLICY

Alters an existing security policy

A security resource is a set of SQL predicates, associated to basic operations (eg. CREATE, READ and so on), that are evaluated for each record to determine if the operation is allowed or not.

Syntax

ALTER SECURITY POLICY <name> 
[

  SET
  ( [CREATE | READ | BEFORE UPDATE | AFTER UPDATE | DELETE | EXECUTE] = (<sqlPredicate>) )*
]
[ 
  REMOVE [CREATE | READ | BEFORE UPDATE | AFTER UPDATE | DELETE | EXECUTE]*
]

• <name> The security policy name. I is used in the GRANT statement to bind it to a role and a resoruce
• <sqlPredicate> a valid SQL predicate

Examples

• Change CREATE and READ predicates for a security policy:

  ALTER SECURITY POLICY foo SET CREATE = (name = 'foo'), READ = (TRUE)
  

• Remove CREATE and READ predicates for a security policy:

  ALTER SECURITY POLICY foo REMOVE CREATE, READ
