firebird

问题 Looking for a good embedded db for my asp.net apps while trying to avoid SQLExpress ( I need it to be a downloable file(s) with no need to install at server ), I found Firebird.

问题 I'm using Firebird 2.1. There is a table name Folders , with the fields: FolderID ParentFolderID FolderName ParentFolderID is -1 if it's the root folder -- otherwise it contains the parent folder's ID. How can I find all parents (up to the root folder) of a low level node? Do I need a recursive query? (Firebird supports them) 回答1: Something like this: WITH RECURSIVE hierarchy (folderid, ParentFolderId, FolderName) as ( SELECT folderid, ParentFolderId, FolderName FROM folders WHERE
