I am trying to pull a report with average down time and I getting the error message "Msg 195, Level 15, State 10, Line 4
'AVG' is not a recognized built-in function name." when I try to run the below query. How can I rephrase the AVG(DateDiff) line to calculate this for me? Also, what would this be called so I can do some additional learning on the topic?
SELECT
TT.PartNumber
,AVG (TT.TimeToRepair) as [Avg Time to Repair (Hours)]
,AVG(DateDiff (hour,TT.TimeDateReported,TT.DateClosed) as [Turnaround Time(Hours)])
FROM dbo.vt_TroubleTicket TT
WHERE TT.Closed = '-1'
and TT.DateClosed between '1/1/2013' and '1/1/2014'
and (TT.PartNumber = '12345')
GROUP BY TT.PartNumber

You need to change your closing parenthesis.

SELECT

TT.PartNumber

,AVG (TT.TimeToRepair) as [Avg Time to Repair (Hours)]

,AVG(DateDiff (hour,TT.TimeDateReported,TT.DateClosed)) as [Turnaround Time(Hours)]

FROM dbo.vt_TroubleTicket TT

WHERE TT.Closed = '-1'

and TT.DateClosed between '1/1/2013' and '1/1/2014'

and (TT.PartNumber = '12345')

GROUP BY TT.PartNumber

Sometimes we miss the little details and just need a different point of view.

Glad I could help.
