class QgsQueryBuilder : QDialog
{
%Docstring
 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.

%Docstring
 Test the constructed sql statement to see if the vector layer data provider likes it.
 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
 statement.
