SNOW-CAD Practice Question: Automating application logic with business rules and scripts
Which script function is used to query the database in a business rule?
⚠ Common exam trap
ServiceNow often tests the distinction between static class references and instance methods, so the trap here is that candidates mistakenly think 'GlideRecord.query()' is valid because they confuse it with other static utility classes like 'GlideSystem' or 'GlideAggregate', forgetting that GlideRecord requires instantiation with 'new'.

Correct answer & explanation
✓
new GlideRecord('table').query();
In ServiceNow, a business rule must instantiate a new GlideRecord object using the 'new' keyword and then call the query() method on that instance to retrieve records from the database. The syntax 'new GlideRecord('table').query()' properly creates a GlideRecord object for the specified table and executes the query to fetch matching records.
