What happens if you use a sub query to get the minimum value for each partition, and then get the min of that?
SELECT MIN(MinIntDate)FROM (SELECT PartitionID, MIN(IntDate) MinIntDate
FROM dbo.ExampleTablePartitioned
GROUP BY PartitionID) a
Hello. I just tried your code and it had the same effect as the regular SELECT MIN(IntDate). It took 10 - 11 seconds each time. There is really no getting around using the Partition Key in the WHERE clause (outside of doing a non-partitioned Index like Paul mentioned).
Take care,
