How to Identify the Error
  1. Open the target automation and select the Activities tab.
  2. Under SQL Query, open the target Query Activity.
  3. Review the Activity Log for error details.
If the log shows "Query failed: Timeout", the error is a query timeout.
Cause
The Query Activity timed out before the query completed execution. The exact root cause may vary, but the following patterns are most commonly reported:
  • Data extensions or system data views (e.g., _Sent, _Click, _PushAddress) have accumulated a large volume of records, causing a full table scan that exceeds the time limit.
  • The query uses a non-SARGable syntax, such as applying a function to the left-hand side of a WHERE clause, which prevents indexes from being used effectively.
  • A rapid change in data volume caused the database to select a suboptimal execution plan.
  • Heavy workloads from multiple processes ran concurrently, causing temporary resource contention.
Resolution
If the timeout is not recurring, a temporary server load spike is the likely cause. Retry the Query Activity, or if necessary, retry the automation in which it is configured.
If the error recurs, optimize the query to reduce execution time. Refer to the following resources for guidance:
