OUTSYSTEMS WEB DEVELOPER STUDY GUIDE EXAM
2026/2027 QUESTIONS AND SOLUTIONS RATED A+
✔✔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 - ✔✔false
layout of the widget is flexible, allowing to add and organize many different widgets the
way you need
✔✔T/F: entity identifiers can be simple primary keys or composite keys - ✔✔False
✔✔what are the types of relationships that can implemented in OutSystems? - ✔✔1to1,
1tomany,manyTomany
✔✔in a many to many relationship, the junction entity must have at least these
attributes - ✔✔an identifier and foreign keys to each parent entity
✔✔when deleting a record form an entity, it deletes all records of an entity with foreign
key references. what is the delete rule that's happening - ✔✔delete
✔✔the on click properties allow defining the behavior of links and buttons and... -
✔✔links and buttons can either navigate to screens or submit requests
✔✔what's the correct screen lifecycle order after clicking a button with the navigate
method - ✔✔run preparation then render the destination screen
✔✔which HTTP request method does the submit method use? - ✔✔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 - ✔✔only the resulting aggregated attribute is part of the aggregate output
when aggregating attributes, the aggregate changes its output and only return the
computed aggregated columns
✔✔what is the correct syntax for writing names of entities and attributes in an SQL
query? - ✔✔{Entity} and {Entity}.[Attribute]
✔✔in an SQL query, the output entities/structures must always be defined to know the
output type - ✔✔yes; must always be defined using entities or structures and match the
columns in the SELECT clause
✔✔the SQL query only allows executing SELECT statements - ✔✔False
✔✔the check box widget is bound to a variable of type..... - ✔✔boolean
✔✔the combo box widget allows selecting one value out of possible alternatives in a
drop down list. what ways can you do this - ✔✔use source entity property to get choices
from entity or static
use source record list property to get choices from list of records
use special list section to manually set special alternatives
✔✔T/F: the list of values displayed on the combo box widget can be a combination of
entity and special list - ✔✔T
✔✔server actions can have the following variables... - ✔✔input, output, local
✔✔when designing the flow of a server action - ✔✔it can have one start node and
multiple (as long as they're different) end nodes like end and raise exception
✔✔in a switch statement, what happens? - ✔✔the first branch that the condition
evaluates to true is executed
if no branch evaluates to true, the otherwise branch is executed
the otherwise branch is required
✔✔if we have multiple exception handlers in an action flow and an exception is raised...
- ✔✔the execution is moved to the exception handler that is most specific to the
exception
