Hi everyone,

 

I'm trying to query using the function PrevVal and it isn't work.

I'm trying to use this syntax:

SELECT PrevVal(TAGNUM('LPBQ1.Producao_Toneladas_Diario'), DATE('-1d'))

 

No rows are return from this query, using any tag.

 

Do you know if is something wrong with this syntax?

 

Thanks

 

Eri
