In my GCSOSUBJECTS table, i need to do an update to the SVCTIME column based on data in the Servetime column. SVCTIME is a datetime value (column is all NULL at this time). The values in Servetime look like:
1654
1021
1628
2310
all represent time of day. How do i (or do i even) cast those values in my update (Update GCSOSUBJECTS set SVCTIME=CAST(ServeTime
as DATETIME)? <-----obviously not working

Thanks

My error reads:
Msg 242, Level 16, State 3, Line 1
The conversion of a nvarchar data type to a datetime data type resulted in an out-of-range value.
The statement has been terminated.

when using


UPDATE gcsosubjects SET ROLE='R', subjecttype='P', comments=generalcomments+'.  '+typeservicecomments, 
DBA=substring(CorpOrDBA,1,40), entered=servedate, feesearned=servicecost, svcdate=servedate, servedby=SERVER, svctime=CAST(ServeTime AS DATETIME)

Ok, plz clarify what the "stuff" is doing. i can see that it is being told to put the ":" in the 3rd position, but what is the "0," for?

SELECT 1654 UNION ALL
SELECT 1021 UNION ALL
SELECT 1628 UNION ALL
SELECT 2310
GO

SELECT ServerTime, CONVERT(datetime,STUFF(Servertime,3,0,':'))
FROM #t
GO

DROP TABLE #t
GO

Results"



ServerTime  
----------- -----------------------
1654        1900-01-01 16:54:00.000

third argument states number of characters it needs to delete from string
i've given 0 as we dont need to delete anything but just needs to insert ':' at 3rd position
