This is just an information for the users that might not know this feature in SQL Server Management Studio, eventhough I’m sure most of people should have known this feature
Basically SQL Server stores all the database usage information including index usage, disk usage, top transaction etc. *This information is not available from the backup file
1. Right click your database, Go to Reports, Go to Standard Reports and you can find all the out of the box reports
Clicking one of the report will give you detailed information – in this sample, I’m using Index Usage Statistics
How to find the top 20 most expensive queries by the total execution time, run this query against the database
SELECT
TOP
20
qs.sql_handle,
qs.execution_count,
qs.total_worker_time AS
Total_CPU,
total_CPU_inSeconds = --Converted from microseconds
qs.total_worker_time/1000000,
average_CPU_inSeconds = --Converted from microseconds
(qs.total_worker_time/1000000) / qs.execution_count,
qs.total_elapsed_time,
total_elapsed_time_inSeconds = --Converted from microseconds
qs.total_elapsed_time/1000000,
st.text,
qp.query_plan
FROM
sys.dm_exec_query_stats AS
qs
CROSS
APPLY sys.dm_exec_sql_text(qs.sql_handle) AS
st
CROSS
apply sys.dm_exec_query_plan (qs.plan_handle) AS
qp
ORDER
BY
qs.total_worker_time DESC
-It will give you this result set
– Clicking the query_plan will give you detailed query plan
