class QgsQueryBuilder : QgsSubsetStringEditorInterface

%Docstring(signature="appended")
Query Builder for layers.

The query builder allows interactive creation of a SQL for limiting the
features displayed in a vector layer.  The fields in the table are
displayed and sample values (or all values) can be viewed to aid in
constructing the query. A test function returns the number of features that
will be returned.

The default implementation tests that the constructed sql statement to

The number of rows that would be returned is displayed in a message box.
The test uses a "select count(*) from ..." query to test the SQL
