Simple query boolean expressions: allow checking without true/false

Aggregates & Queries

Development Environment 11.0.109.0

Normal expressions allow booleans to be evaluated without comparison, and the not operator, e.g.:

if(not myBool, "hello", "hi")

In simple query expressions however, we need to explicitly check against True or False, and the not operator is not allowed:

Entity.Attribute = False

I'd consider that bad coding style in a normal expression. Why can't we use "proper" boolean expressions in simple queries?

Merged this idea with 'Disable the mandatory condition (=true / =false) when setting a filter on an aggregate with a boolean attribute.' (created on 2017-08-10 10:54:37 by Paulo Zacarias)

The idea here is to let the developer use only the boolean attribute name when setting a filter on an aggregate with it, instead of the attribute name plus the condition (=true or =false).

Please see the attached pictures as an example.

I think it would be useful if it was possible to filter aggregates with just boolean variables, with a boolean variable IsActive as an example:

- IsActive = true -> IsActive

- IsActive = false -> Not IsActive
