> ij> select * from t1 left outer joing t2 on t1.c2=t2.c1;
> ERROR 42X01: Syntax error: Encountered "left" at line 1, column 18.
> I don't know if this is a PITA to fix or not, but I thought

> This appears to be a problem with hand-coded lookahead logic. Although fixing this particular
lookahead issue might be trivial, this is part of a larger problem since the parser is liberally
peppered with similar hand-coded lookahead logic. Coming up with a general solution might
involve some creativity.
