Some part of this parser is too powerful? about scala-sql-parser

Hi,

I actually think this is valid sql. For instance, sqlite agrees with me:

sqlite> select * from user where user.age=26=0; 
stephentu|27
stephentu|1

ha, mysql accept this, but oracle don't

i tried this sql, it also pass the test

select user and name from table;

[stephentu]

Once again, I think this is valid sql as well:

sqlite> create table t (user varchar(10), name varchar(10));
sqlite> select user and name from t;
sqlite>

[jadetang]

try this sql

select user and name from table;

in three database in production, the result is:
vertica: wrong
oracle: wrong
mysql: sql not return column 'name' and 'user',instead return 0 for each row.

select user and name from table where max(user)=1;

is wrong in oracle, because the 'group function is not allowed'. I guess it is same for other databases.
