These are implementation details only, and should not be part of the stable API. We need the flexibility to change these at any stage without being bound by any API contract.

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.

|

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.
