Question

語法錯誤，我有以下帕拉查詢

select session_id, max(cast(milli_ts) as integer), min(cast(milli_ts) as integer)from my_table group by session_id 

但得到了以下錯誤：

          ^
Encountered:) 
Expected: AND, AS, BETWEEN, DIV, ILIKE, IN, IREGEXP, IS, LIKE, NOT, OR, REGEXP, RLIKE 

CAUSED BY: Exception: Syntax error 

任何想法，我錯過了什麼？謝謝！
