SAP HANA alternative for cross apply

问题

Is there an alternative in HANA sql for the "cross apply" operator as available in MsSql? Or is there a way to apply a function for values in a table? Something like

select T.*, F.* from T cross join someFunction(T.Value) F

回答1:

You can use the cross join in SAP HANA, that's not a problem. However, if you want to apply a function to all entries of T.VALUE then the query needs to look like this:

select T.*, someFunction(T.Value)
from T cross join F
