FILL Clause to Handle Missing Timebuckets | Teradata Vantage - Using the FILL Clause to Handle Missing Timebuckets - Advanced SQL Engine - Teradata Database

If an entire timebucket is missing a particular value from the aggregate result rows, you can use the FILL clause to set the values. Several FILL values are provided. The FILL clause must follow a GROUP BY TIME clause. For information about the FILL clause syntax and the available values, see GROUP BY TIME Clause.

When the FILL clause is omitted from the GROUP BY TIME clause, the missing timebuckets are ignored.
