Bookmarks - Mastering phpMyAdmin 2.8 for Effective MySQL Management - page 210

Bookmark Parameters
If we look again at the first bookmark we created (finding all books for author 1 ), we
realize that, although useful, it was limited to always finding the same author.
A special query syntax enables the passing of parameters to bookmarks. This syntax
uses the fact that SQL comments enclosed within /* and */ are ignored by MySQL.
If the /*[VARIABLE]*/ construct exists somewhere in the query, it will be expanded
at execution time with the value provided when recalling the bookmark.
Creating a Parameterized Bookmark
Let's say we want to find all books for a given author when we don't know the
author's name. We first enter the following query:
SELECT authors.author_name, authors.author_id, books.title
FROM books, authors
WHERE books.author_id = authors.author_id
/* AND authors.author_name
LIKE '%[VARIABLE]%' */
The part between the comments characters ( /* */ ) will be expanded later, and the
tags removed:
We label it and click Go . The first execution of the query just stores the bookmark.
