SQL Query needed for desired Output - sql

Question

Below is the sample data which gets filled into sql server database from different PLC machine. datetime,machineID, cycletime(TIME TAKEN TO PRODUCE THAT MATERIAL) AND shift
There are 3 shifts in company A(6:30Am to 2:30PM), B(2:30 to 10:30), C(10:30 to 6:30AM).
when i take C Shift count, my query should take next day data also till 6:30AM time. Where as A shift should take current day data starting from 6:30Am to 2:30Pm.Where as B shift should take current day data starting from 2:31pm to 10:30PM.
Desired Output::
I need to find the quantity for each hour...6:30 to 7:30 what is the quantity... 7:30 to 8:30 what is the quantity and so on for each individual hour. Quantity should not get added with previous hour quantity.. individual hour quantity

Answer 1

You can start with this, and then wrap it with
"SELECT ... just the columns you want
FROM this example
GROUP BY ...."
SELECT
-- isolate Date from Time from HourMinutes only for testing
CONVERT(VARCHAR(10), [MDate], 111) as RealDate
,CONVERT(VARCHAR, [MTime], 108) as RealTime
,SUBSTRING(CONVERT(VARCHAR, [MTime], 108),4,5) as HrMn
-- from midnight to 6:30 adjust to prior day
, Case When (CONVERT(VARCHAR, [MTime], 108) < '06:30:00')
Then CONVERT(VARCHAR(10), DATEADD(day,-1,[MDate]), 111)
Else CONVERT(VARCHAR(10), [MDate], 111)
End as RptDate
-- from after the half hour, report it with the next hour
,Case When (SUBSTRING(CONVERT(VARCHAR, [MTime], 108),1,5)) > '23:30:00'
Then ' 0:30'
When (SUBSTRING(CONVERT(VARCHAR, [MTime], 108),4,5)) > '30:00'
Then STR(DATEPART ( hour , [MTime] ) + 1, 2) + ':30'
Else STR(DATEPART ( hour , [MTime] ), 2) + ':30'
End as RptHour
,[MachinelD]
,[CYCLETIM]
,[Shift]
FROM [StackOver].[dbo].[CShift]
For your add-on question of getting only Previous or Current shift,
we need to think ahead to what the Where clause might look like--
Where (MDate = #fromDate and MTime >= #fromTime)
Or (MDate > #fromDate)
And then, before the main SELECT/FROM, create appropriate local vars --
Declare #fromDate as datetime, #fromTime as datetime
If CONVERT (time, GETDATE()) <= '06:30:00' Begin
Set #fromDate=DATEADD(day,-1,CONVERT (date, GETDATE())) --yesterday
Set #fromTime='14:30'
End
Else If CONVERT (time, GETDATE()) <= '14:30:00' Begin
Set #fromDate=DATEADD(day,-1,CONVERT (date, GETDATE())) --yesterday
Set #fromTime='22:30'
End
Else If CONVERT (time, GETDATE()) <= '22:30:00' Begin
Set #fromDate=CONVERT (date, GETDATE()) --today
Set #fromTime='06:30'
End
Else Begin -- time > 22:30
Set #fromDate=CONVERT (date, GETDATE()) --today
Set #fromTime='14:30'
End
-- for testing only, show the values
Select #fromDate, #fromTime
I leave any remaining question(s) to your own solution
