USE keyword

Keywords:  select method

The keyword can be written in capital or small letters, but not mixed. The USE operation corresponds to the OQL SELECT statement except that it refers to a view definition in the database model, which contains the assignment rules. The USE keyword requires a view name as parameter, which has been defined in the database or in the expression. Typicalle, the USE operation is called without left operand or with a collection as left operand on which it applies. It is not suggested appling the USE operation on more complex access paths.

In order not to misinterpret the USE operand with the Property::use() function, capital letters are suggested.

Definition: 

_use                  := 'use'          | __use

__use                 :: 'USE'
