create view [dbo].[SP_AHU_data] as SELECT cast(TrendLog.TrendLogId as bigint) as TrendLogid , TrendLog.TrendLogGuid, TrendLogValue.LogTime,cast(TrendLogValue.LogValue as double) as LogValue FROM TrendLog INNER JOIN TrendLogValue ON TrendLog.TrendLogId = TrendLogValue.TrendLogId where TrendLog.TrendLogGuid in('{DCCFB6EA-C606-4168-A2B3-FC1059173DAF}', '{B1D5B0E8-44E2-459B-BC53-1CCE00FE7E6E}', '{7493BB54-DC88-4ECF-81DA-3AEBCC698808}', '{9641A376-D03D-46B7-9780-20DAC28AA3D9}')
Il y a deux tables TrendLog et TrendLogValue
Trendlog a 2 colonnes
trendLogValue a 3 colonnes
Essayez d'append des alias comme ci-dessous et changez le double
pour float
create view [dbo].[view_name] as SELECT cast(Table1.col1 as bigint) as col1, Table1.col2, Table2.col3, cast(Table2.col4 as float) as col4 FROM Table1 INNER JOIN Table2 ON Table1.col1 = Table2.col1
