ORA-30452
cannot compute AVG(X), VARIANCE(X) or STDDEV(X), without COUNT(X) or SUM(X)
Cause
Incremental refresh of summaries requires a COUNT(X) column in order to incrementally refresh AVG(X). It requires both SUM(X) and COUNT(X) columns in order to in refresh STDDEV(X) or VARIANCE(X)
Action
Make sure that the required columns are part of the summary definition if incremental refresh capability is desired.
