Selecting Output Fields
There are several ways to add a field to the query output field list:

Select the field name in the 
Query Building Area. To include all the fields of the object, select the list item with an asterisk in the field name area.

Select a field name from the 
Expression column drop-down list in the 
Columns Pane.

Enter a valid expression in the 
Expression column in the 
Columns Pane.
There are two ways to remove a field from the list of query output fields:

Clear the checkbox at the left of the field name in the 
Query Building Area.

Clear the 
Output column checkbox.
Using the drop-down menu, you can remove lines from the Columns Pane or re-order output by right clicking on the leftmost gray column.
Define any output field aliases in the 
Alias column of the 
Columns Pane.
