Extended Query Parameter

Extended query parameter

As you have seen in the introduction the basic filter in the extended query are the selected Project and Additional projects. You may introduce additional query restrictions for description data, description scopes and descriptor conditions, which are shown in the Query parameter area. By clicking on button Add description, Add scope or Add descriptor in the Query parameter tool strip a query parameter control is inserted at the end of the query parameter list. When you enter query parameter, the field Matches: will be updated immediatly. To see the Result list, you will have to click on button Show matches (see picture below). 

If you have entered several parameter controls, you might wish to de-activate one of them temporarily, e.g. to check its effect on the result list. Remove the check mark in the beginning of the first line of the query parameter (see item 1 in image below) and the whole condition will be ignored. Below this check box you find by default the symbol (see item 2 in image below), which means “logical AND”. If you specify several query parameter controls, which are all adjusted to , a matching description must fulfill all entered query conditions simultaneously.

You may click on the symbol to change it to (see item 3 in image below), which means “logical OR”. In this case the result list will include all descriptions that fulfill the first descriptor condition and additionally all descriptions, which fulfill the second condition. I.e. each “AND” condition will reduce the list of matching descriptions and each “OR” condition will add its matching descriptions to the result list.  

By clicking on a parameter control it is selected as the active control (see above). The active parameter control is shown with light blue background. The resulting SQL query may be viewed with button . You can delete the current query control by clicking on button Remove or all query controls by clicking on button in the Query parameter tool strip.
