'SELECT * FROM file' without WHERE clause returns only 'Not Matched'

Products

• Carbon Black Cloud Enterprise EDR (formerly Cb Threathunter)

Issue/Introduction

• Trying to search without a WHERE clause returns no results, only Not Matched on the file table
• Query shows as complete, but no device returns results

  Example
  SELECT * FROM file;
  
  Results
  All devices included in query show 'Not Matched'

Environment

• Carbon Black Cloud Console: All Versions
  • Audit and Remediation (was CB LiveOps)
• OS Query: 2.11.2 - Current

Cause

The file table requires a WHERE clause (otherwise known as an argument) to return results

Resolution

Ensure searches against the file table and any other table requiring arguments include a WHERE clause

Additional Information

• Review the documentation on Tables with arguments and the schema documentation page for details on which tables require arguments
• Typically tables with a large number of non-repeating data (like all files and directories for a given machine) will require a WHERE clause to run successfully
• OSQL reports identifying tables requiring arguments with a dropper icon, maintenance of this list is not under the control of Carbon Black
