Use this Window to build or modify an individual Query Column. You open this window by clicking on NEW or MOD in the GUI Columns tab.
If you are building a Summary Query, the Function list will just be the aggregate functions (sum, avg, min, max).
You can specify a literal, expression or system variable, by checking the Query Column is a literal box.
You can also use this method for specifying a sub-select or case statement. For large expressions such as these,click on the >>> for a larger box.
AQT provides no assistance for building a sub-select or case, though this may be done in a later release.
