Convert Access Queries To SQL

I have an Access database that used to produce a mass of Performance Indicators from Access tables. The data is now held on SQL Server and I run the Access queries from the SQL tables. I wouldlike to move all the queries over to SQL but not sure if I can do that. Here's an example of one of the queries (the SQL view)

SELECT tblCalls.*
FROM tblCalls
WHERE (((tblCalls.Call_date)>=[Forms]![ReportParams]![SDate] And (tblCalls.Call_date)<=[Forms]![ReportParams]![EDate]) AND ((tblCalls.NotAccepted)=False) AND ((tblCalls.Completed_time) Is Not Null) AND ((tblCalls.Category)="fly tipping"));


SELECT Month([Call_date]) AS Mnth, DateSerial(Year([Call_date]),Int((Month([Call_date])-1)/3)*3+4,0) AS Qtr, Sum(Work_Days([Call_date],[Completed_time])) AS RespTime, Sum(1) AS Count, Sum(Work_Days([Call_date],[Completed_time]))/[Count] AS AvgTime
FROM qryFlyTippingStatsSummary1
GROUP BY Month([Call_date]), DateSerial(Year([Call_date]),Int((Month([Call_date])-1)/3)*3+4,0)
ORDER BY Month([Call_date]), DateSerial(Year([Call_date]),Int((Month([Call_date])-1)/3)*3+4,0);
