From Alex.Hillman@usmint.treas.gov Thu, 06 Sep 2001 12:31:09 -0700 From: "Hillman, Alex" Date: Thu, 06 Sep 2001 12:31:09 -0700 Subject: When optimizer reevaluate SQL statement Message-ID: MIME-Version: 1.0 Content-Type: text/plain Let's assume that SQL statement was parsed by user X. If this or another user reexecute this same statement what are the conditions that this SQL statement will be reparsed? Let's assume that privileges are not changed and tables and/or views are not dropped and views are not changed. And optimizer parameters are not changed. First come to mind is dropping index. What about reanalizing one of the object - theoretically should also reparse. Anything else? Also is there possibility to force reparsing of SQL statement if let say index was added - short of flashing shared pool?
