SNOW-CSA Database Administration and CMDB Practice Question
A scheduled job runs a transform map to import data into the CMDB from an external asset management system. The transform map has a field mapping that uses script to derive the CI class based on asset type. Recently, imports have been failing with a 'GlideRecord: Invalid table name' error. What is the most likely cause?
⚠ Common exam trap
Many exam-takers confuse 'Invalid table name' with a data quality issue (Option A) or a configuration error in the transform map target (Option D), but the error is specifically tied to the dynamic table name returned by the script, not static configuration or external data format.
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 script in the field mapping is returning a value that does not correspond to an existing table name.
The error 'GlideRecord: Invalid table name' indicates that the script in the field mapping is returning a string that does not match any existing table (class) in the CMDB. When a transform map uses a script to derive the CI class, the returned value must be a valid table name (e.g., 'cmdb_ci_server'). If the script returns a misspelled, malformed, or non-existent table name, GlideRecord fails to instantiate the record, causing the import to fail.
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 external system is sending malformed data.
Why it's wrong here
Malformed data might cause parsing issues, but the error is specifically about an invalid table name, likely from the script.
- ✗
The scheduled job does not have the right roles.
Why it's wrong here
Access issues cause permission errors, not 'Invalid table name'.
- ✓
The script in the field mapping is returning a value that does not correspond to an existing table name.
Why this is correct
If the script sets sys_class_name to a non-existent table, GlideRecord will throw 'Invalid table name'.
- ✗
The target table name in the transform map is misspelled.
Why it's wrong here
A misspelled target table would cause an error during import set mapping, not specifically 'Invalid table name' from GlideRecord.
