I'm trying to only return the STOREID and POLL_TIME in a query based on the @StartDate. Each STOREID has multiple entries for each date so I'm getting something like this currently:

StoreID     POLL_TIME
1               5:57
1               6:23
1               7:23
2               1:42
2               4:23


I only want to return this:

StoreID     POLL_TIME
1               7:23
2               4:23

Any help here?
SELECT 
	SUMMARY.STOREID, 
	SUMMARY.POLL_TIME
FROM 
	SUMMARY 
WHERE 
	SUMMARY.Current_Batch_Date = @StartDate
	
ORDER BY 
	STOREID
