> It seems the cast syntax in Phoenix is not in line with SQL-92/99 (1), as well as other common SQL databases (2 & 3).
> A typical cast statement in SQL is written as
> {code}
> SELECT CAST(ID AS INTEGER) FROM MYTAB;
> {code}
> but this leads to a parse error in Phoenix. Instead, Phoenix expects cast statements to be written as follows (I believe the parentheses are optional here)
> {code}
> SELECT (CAST ID AS INTEGER) FROM MYTAB;
> {code}
