SNOW-CAD Core Application Development Practice Question

Which TWO of the following are valid ways to retrieve a single record from a GlideRecord query on the task table?

⚠ Common exam trap

A common mix-up: candidates confuse `getUniqueValue()` with retrieving the record itself, or mistakenly think `getByID()` is a valid method because of its similarity to `get()` or `getByID()` in other platforms, while ServiceNow strictly uses `get(sys_id)`.

Correct answer & explanation

✓

gr.next()

`gr.next()` is the standard method to advance the cursor to the next record in a GlideRecord query result set. When called after a `query()`, it retrieves the first record (or subsequent records) and returns true if a record exists, making it a valid way to access a single record. Option D is correct because `gr.get(sys_id)` retrieves a single record by its sys_id directly, without needing a prior query, and returns true if the record is found.
