+If a column header is a hyperlink (red), click the column you would like to sort by. Clicking the same header again reverses the order.
+
+== Changing Report Numbering
+
+There may be instances where you need to change the ID of the report, perhaps to organize the reports better. At present this requires changes to the trac database. The ''report'' table has the following schema:
+ * id integer PRIMARY KEY
+ * author text
+ * title text
+ * query text
+ * description text
+Changing the ID changes the shown order and number in the ''Available Reports'' list and the report's perma-link. This is done by running something like:
+{{{#!sql
+UPDATE report SET id = 5 WHERE id = 3;
+}}}
+Keep in mind that the integrity has to be maintained, ie ID has to be unique, and you don't want to exceed the max, since that's managed by SQLite someplace.
+
+You may also need to update or remove the report number stored in the report or query.
 
 == Navigating Tickets
 
-Clicking on one of the report results will take you to that ticket. You can navigate through the results by clicking the ''Next Ticket'' or ''Previous Ticket'' contextual navigation links, or click the ''Back to Report'' link to return to the report page.
-
-You can safely edit any of the tickets and continue to navigate through the results using the ''!Next/Previous/Back to Report'' links after saving your results, but when you return to the report, there will be no hint about what has changed, in contrast to the query results (see TracQuery#NavigatingTickets).

 === A note about SQL rewriting #rewriting
 
 Beyond the relatively trivial replacement of dynamic variables, the SQL query is also altered in order to support two features of the reports:
- 1. [#sort-order sorting]
- 1. pagination: limiting the number of results displayed on each page
+ 1. [#sort-order changing the sort order]
+ 1. pagination support (limitation of the number of result rows displayed on each page)
 In order to support the first feature, the sort column is inserted in the `ORDER BY` clause in the first position or in the second position if a `__group__` column is specified (an `ORDER BY` clause is created if needed). In order to support pagination, a `LIMIT ... OFFSET ...` clause is appended.
 The query might be too complex for the automatic rewrite to work correctly, resulting in an erroneous query. In this case you still have the possibility to control exactly how the rewrite is done by manually inserting the following tokens:
