:line 1:100 cannot recognize input near ' ' ' ' ' ' in statement

HQL的書寫，select * from (select * from table) ;

 執行此HQL，應該會報錯：ql.Driver (SessionState.java:printError(960)) - FAILED: ParseException line 48:52 cannot recognize input near '<EOF>' '<EOF>' '<EOF>' in subquery source

 此時，修改HQL為select * from (select * from table) a，執行成功。
