This chapter covers one of the linked-tables infrastructure's features: query bookmarks. Being able to label queries and recall them by label can be a real time saver. In Chapter 12, we learned about the SQL history feature, which automatically stores queries (temporarily or permanently).
Bookmarks are queries that are:
Stored permanently
Viewable
Erasable
Related to one database
Recorded only as a consequence of a user's wish
Labeled
Private by default (only available to the user creating them), but possibly public
A bookmark can also have a variable part, as explained in the Passing a Parameter Value to a Bookmark section later in this chapter.
There is no bookmark sub-page to manage bookmarks. Instead, the various actions on bookmarks are available on specific pages such as results pages or query box pages.
