A method, system, and/or computer program product revises a policy that provides rules on how to alter statements to access or manipulate data in a database. A user interface (UI) has a field containing a sample database query statement. The sample database query statement is parsed into clauses, where each clause depicts a specific type of grammatical structure. A different hyperlink is associated with each of the clauses. In response to receiving a signal activating a particular hyperlink for a particular clause, change options, for the particular clause, are presented from a resource that presents change options for the specific type of grammatical structure. User-selected changes to the particular clause are incorporated into a new rule, which causes a clause of the particular type of grammatical structure in any database query statement to be changed. Each change becomes a new rule in a revised policy.
