Verify Whether a User Exists in the Database
Last reviewed: September 29, 2026
Use this article when a Scenario Editor or Service Suite validation needs to confirm whether a specific user record exists in a database.
What changed in this article
- Rewrote the question-style title into a database validation task.
- Added checks for parameterized queries, database connection settings, permissions, expected row count, and negative-case validation.
- Added a safety note to avoid logging passwords, tokens, email addresses, or sensitive user attributes from query results.
Validation workflow
- Identify the unique user key to validate, such as username, user ID, or test email.
- Run a parameterized query through the approved AIQ database/service workflow.
- Assert the expected row count or field value, then run a negative case to confirm the validation can fail correctly.
Review note: The article now focuses on safe database validation instead of a broad yes/no question.
