> Teiid's DAYOFWEEK function:
> {code:plain}
> DAYOFWEEK(x) 	Return day of week (Sunday=1, Saturday=7) 
> {code}
> is pushed down as:
> {code:plain}
> dayname(g_0."DATEVALUE")
> {code}
> but this function returns string representation of the day.
> More appropriate would be to push DAYOFWEEK as WEEKDAY function, but the returned value has to be adapted to Teiid's representation (Sunday=1 and Saturday=7, vs. HANA's Monday=0,Sunday=6). So the solution would be to push:
> {code:sql}
> MOD((WEEKDAY(datevalue)+1),7)+1
> {code}
