GlideRecord query returned no results for expected record

Incorrect table name specified in the GlideRecord constructor, including typos or referencing a non-existent table extension. (high likelihood)

Wrong encoded query syntax or field names that don't match the actual table schema, causing the query to match no records. (high likelihood)

Missing or incorrect Access Control Rules (ACLs) preventing the user context from reading records that actually exist in the table. (medium likelihood)

Query executing against empty table or records were recently deleted, making previously valid queries return no results. (medium likelihood)

Script running in wrong application scope, preventing access to scoped tables or records in different application contexts. (low likelihood)

Step 1: Verify the table name in your GlideRecord constructor by checking System Definition > Tables and confirming the exact table name spelling and case sensitivity.

Step 2: Test your encoded query in a filter on the actual table through the ServiceNow interface to confirm it returns expected records before using it in code.

Step 3: Add debugging by logging the query details using gs.info() before executing, including table name, encoded query, and getRowCount() to verify record existence.

Step 4: Check Access Control Rules under System Security > Access Control (ACL) to ensure your user context has read access to the target table and fields.

Step 5: Run the query as an admin user temporarily to determine if ACL restrictions are causing the no results condition.

Step 6: Verify your script's application scope matches the table's scope by checking both the script's and table's application assignments.

Step 7: Add proper error handling with hasNext() or next() validation before accessing GlideRecord fields to prevent assuming records exist.

Step 8: Review recent data changes or imports that might have affected the expected records by checking System Logs > Data Sources or recent update sets.
