Query Layer

The Query Layer interface is used to define a query expression and the color used to highlight the selected objects obtained when the query is applied.  A query expression is defined by a restriction clause (WHERE clause).

It is accessible through:

    Layer Explorer > Right Click over an layer name > Query...
or
    Layer > Query...

This interface consists of the following steps:

1. Input Layer - Select the input layer.
2. Criteria - Defines the restriction clause.
3. Layer Selection options:
• Add: Transforms the query result in the layer selected items, adding the query results to the layer selection.
• New: Transforms the query result in the layer selected items and remove previous layer selection.
• None: The result will be just painted over the map.
• Highlight:  Sets the color to be used to highlight the selected objects.
