Problem Statement: Script to find top 10 high memory consuming Queries.
Solution:
SELECT TOP 10 Object_name(qt.objectid)
AS 'SP Name',
Substring(qt.text, ( qs.statement_start_offset / 2 ) + 1,
(
( CASE qs.statement_end_offset
WHEN -1 THEN Datalength(qt.text)
ELSE qs.statement_end_offset
END
-
qs.statement_start_offset ) / 2 ) + 1)
AS statement_text,

qs.execution_count
AS 'Execution Count',
total_logical_reads / qs.execution_count
AS 'AvgLogicalReads',
qs.execution_count / Datediff(minute, qs.creation_time, Getdate())
AS
'Calls/minute',
qs.total_worker_time / qs.execution_count
AS 'AvgWorkerTime',

AS 'TotalWorkerTime',
qs.total_elapsed_time / qs.execution_count
AS 'AvgElapsedTime',
qs.total_logical_writes,
