I have a reasonably long SQL query that I need to run in a .Net application. I can make it a stored procedure but I’d like to avoid it if possible (given that I may have a high number of queries in this app).
With this in mind, could something like the following be converted to LINQ or is it too detailed?
-- Compare current period to historical data
select Name ,
avg(TimeProcessing + TimeRendering + TimeDataRetrieval) / 1000 as 'Current Month' ,
isnull(count(TimeProcessing), 0) as 'Sample' ,
min(l2.[Avg_Exec_Time_Previous_Month]) as 'Previous Month' ,
isnull(min(l2.[Executions_Last_Month]), 0) as 'Sample' ,
min(l3.[Avg_Exec_Time_Two_Months_Ago]) as 'Two Months ago' ,
isnull(min(l3.[Executions_Two_Months_Ago]), 0) as 'Sample'
from marlin.report_execution_log l
inner join marlin.report_catalog c on l.ReportID = c.ItemID
left outer join (
select
l2.ReportID ,
(
avg(l2.TimeProcessing + l2.TimeRendering
+ l2.TimeDataRetrieval) / 1000
) as 'Avg_Exec_Time_Previous_Month' ,
count(l2.TimeProcessing) as 'Executions_Last_Month'
from
marlin.report_execution_log l2
where
TimeEnd between dateadd(MONTH, -2, getdate())
and dateadd(MONTH, -1, getdate())
group by
l2.ReportID
) l2 on l.ReportID = l2.ReportID
left outer join (
select
l3.ReportID ,
(
avg(l3.TimeProcessing + l3.TimeRendering + l3.TimeDataRetrieval) / 1000
) as 'Avg_Exec_Time_Two_Months_Ago' ,
count(l3.TimeProcessing) as 'Executions_Two_Months_Ago'
from
marlin.report_execution_log l3
where
TimeEnd between dateadd(MONTH, -3, getdate())
and dateadd(MONTH, -2, getdate())
group by
l3.ReportID
) l3 on l.ReportID = l3.ReportID
group by l.ReportID ,
Name
order by 2 desc
