Subqueries in Other Clauses
Subqueries in SELECT, WHERE, and HAVING Clauses
Subqueries in these clauses are highlighted like hyperlinks. You can add subqueries to these clauses by typing them instead of columns. To open such subquery for visual editing, click them holding the CTRL key. Subqueries in the SELECT clause may be renamed by entering name into the Alias column.
Subqueries in GROUP BY and ORDER BY Clauses
Subqueries in these clauses should always return only one value (i.e. one row having one column). To add such subquery, type it into the expression box and press ENTER. You can open them for visual editing only by navigating to them with Document Outline.
