ZDataQueryKit - QueryColumns.stx

    Description

        This form allows you to choose which columns should be available
        in the output data, and what they should each be called.

    Controls

        'Output' -- Check this to add the column to the output.

        'Table.Column' -- The datasource name, and column name of this
        column.

        'Alias' -- What the column should be called in the output data.

        'Update' -- Save your changes.

    Note:

        In ZVisualQuery and ZVisualODBCClient pressing Update regenerates
        the SQL for the query. In ZVisualODBCClient this has the effect
        of invalidating the cached results, so next time the query is run
        new data will be retrieved from the database.
