Gabriel Reid created PHOENIX-836:
------------------------------------
Summary: Cast syntax is not in line with standard SQL
Key: PHOENIX-836
URL: https://issues.apache.org/jira/browse/PHOENIX-836
Project: Phoenix
Issue Type: Bug
Reporter: Gabriel Reid
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}
