to....
integer
entities are created with a set of entity actions for CRUD operations. What are
they?
create, createOrUpdate, Update, Get, Delete, GetForUpdate
T/F: input parameters are always mandatory
F
output parameters are available where?
both inside and outside of their implementation scope
a value must be assigned to the output param inside to be returned to the outside
a structure can have attributes of the following data types:
basic, structure, entity, and list
a list in outsystems is
a collection of elements of the same data type
what does the widget tree represent?
the hierarchy of the widgets on the screen
what type of variables can be created inside a screen?
input parameters and local variables
screens do not have output params
what is the main purpose of the screen preparation?
fetch data from the databases
T/F: In the screen lifecycle, the preparation runs on the browser.
False
preparation contains server-side logic that is executed before rendering the screen
in an aggregate, the sources section is used for
define the entities we want to retrieve records from
in an aggregate, the purpose of the test values section is....
define values for testing the preview data of the aggregate
, how can we limit the number of records returned by an aggregate?
use the max records property
is it possible to see the SQL generated by an aggregate?
Yes
in the executed SQL property
the expression widget
displays text calculated at runtime
the image widget
displays static images, images in an URL, and images in the database
the table records widget
displays records in a tabular layout, one per row
T/F: the form widget only allows input and label widgets

POST
ending a screen action with an end element or a destination to the current screen
yields the same result
false
end preserves the values of the screen variables and widgets
destination resets them to their defaults
when doing a "with or without" join between two entities, it returns
all records from the left entity even if there is no match in the right entity
LEFT JOIN
when columns are hidden in an aggregate
they are still part of the output of the aggregate
when using an aggregate function like Sum, average, min, max, or count on an
attribute
