SNOW-CSA Database Administration and CMDB Practice Question
Exhibit
```javascript
var gr = new GlideRecord('cmdb_ci');
gr.addQuery('sys_class_name', 'cmdb_ci_server');
gr.addQuery('u_environment', 'production');
gr.setLimit(1);
gr.orderByDesc('sys_updated_on');
gr.query();
if(gr.next()) {
gs.info(gr.getValue('name'));
}
```Refer to the exhibit. The script runs but no output is produced. What is the most likely cause?
⚠ Common exam trap
Test-takers frequently assume 'no output' means 'no records matched the query' (Option A), but the real issue is that the script runs successfully yet prints nothing because the field being accessed does not exist on the queried records.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The field 'u_environment' does not exist on records with sys_class_name='cmdb_ci_server'.
The script uses `getValue('u_environment')` on a GlideRecord query for `cmdb_ci` with `sys_class_name='cmdb_ci_server'`. If the field `u_environment` does not exist on that table or class, `getValue` returns null, and the `gs.print` statement outputs nothing (or an empty string). The script runs without error, but no output is produced because the field is missing, not because the query returns zero rows.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The table 'cmdb_ci' has no records with sys_class_name='cmdb_ci_server'.
Why it's wrong here
There could be servers but the query might still fail due to field issues.
- ✗
The orderByDesc method is misspelled (should be orderByDescending).
Why it's wrong here
orderByDesc is a valid GlideRecord method.
- ✗
The script lacks point number of rows (no rows with condition).
Why it's wrong here
This is a restatement, not a root cause.
- ✓
The field 'u_environment' does not exist on records with sys_class_name='cmdb_ci_server'.
Why this is correct
A missing field causes the query to return no results.
