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

HQL的书写，select * from (select * from table) ;

 执行此HQL，应该会报错：ql.Driver (SessionState.java:printError(960)) - FAILED: ParseException line 48:52 cannot recognize input near '<EOF>' '<EOF>' '<EOF>' in subquery source

 此时，修改HQL为select * from (select * from table) a，执行成功。
