UnusedimagesPage::getSQL (  ) 

Subclasses return an SQL query here.

Note that the query itself should return the following four columns: 'type' (your special page's name), 'namespace', 'title', and 'value' *in that order*. 'value' is used for sorting.

These may be stored in the querycache table for expensive queries, and that cached data will be returned sometimes, so the presence of extra fields can't be relied upon. The cached 'value' column will be an integer; non-numeric values are useful only for sorting the initial query.

Don't include an ORDER or LIMIT clause, this will be added.
