| Subclasses return an array of fields to order by here. | |

 Public Member Functions inherited from PageQueryPage | |
| formatResult ( $skin, $row) | |

◆ getQueryInfo()
| DeadendPagesPage::getQueryInfo | ( | ) |
Subclasses return an SQL query here, formatted as an array with the following keys: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => options join_conds => JOIN conditions.
Note that the query itself should return the following three columns: 'namespace', 'title', and 'value'. '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 (except if they're timestamps, see usesTimestamps()).
Don't include an ORDER or LIMIT clause, they will be added.
If this function is not overridden or returns something other than an array, getSQL() will be used instead. This is for backwards compatibility only and is strongly deprecated.
