Use Cases

  • Dictionary lookup and field explanation
  • SQL filtering and grouping
  • Analytical reporting and reusable query building

Common Usage

  • identify canceled NASA awards
  • measure timing between award and cancellation
  • exclude canceled awards from active award counts

Common Mistakes

  • using it as the award execution date
  • assuming null means the award is active without checking other status fields

Query Guidance

Parse the string to a date or timestamp, then filter for non-null values to find canceled awards. Use it in date-range predicates, grouping, or lifecycle analysis, but do not join or compare it as a raw string unless the source format is guaranteed to be ISO-ordered.
