> This query: SELECT INTKEY, RAND() FROM SmallA works for all source except Teradata. With TD it get this exception:
> [Teradata Database] [TeraJDBC 13.00.00.06] [Error 3706] [SQLState 42000] Syntax error: expected something between '(' and ')'.
> After looking at the TD Web site, I found it expects the RANDOM function with low and high limits (integers). It expects something like: SELECT INTKEY, RANDOM(2,6) FROM SmallA
> It would appear we need to be able to pass the function in that form to the source.
> If I try to query (through a VDB) SELECT INTKEY, RANDOM(2,6) FROM SmallA or SELECT INTKEY, RAND(2,6) FROM SmallA, Teiid reports the function is in an unknown form. (This wasn't a surprise.)
