Setting output fields


The Selection tab displays the output fields of the query as a grid.

 

The grid allows you to edit the names of the query output fields, specify their display order and set the aggregate functions for each field. To remove a field from the list, right-click the field row and select the Delete current row popup menu item.

The popup menu also allows you to insert a nested query and add a CASE clause. To edit the CASE clause, use the CASE END AS dialog.

If you check this option, the duplicate records (if any) are not included into the query result (i.e. the DISTINCT keyword is added to the SQL query text).
