ParseException line 6:5 无法识别 joinSource 中 '(' 'SELECT' 'system' 附近的输入

Question

我正在尝试在 hive 中执行查询并收到错误消息。我一遍又一遍地检查，但我没有发现任何问题。

CREATE view sta_v_clean_phrase_longtext (system, `function`, loglockmod, extinfo 
, primarykey, foreignkey, flgprimkey, flgfrgnkey, ref_recn, text_line, copied, 
inserted ) 
AS 
  SELECT system, 
         `function`, 
         loglockmod, 
         extinfo, 
         primarykey, 
         foreignkey, 
         flgprimkey, 
         flgfrgnkey, 
         ref_recn, 
         Concat_ws('', Collect_list(text_line))AS TEXT_LINE, 
         copied 
  FROM  (SELECT system, 
                `function`, 
                loglockmod, 
                extinfo, 
                primarykey, 
                foreignkey, 
                flgprimkey, 
                flgfrgnkey, 
                ref_recn, 
                text_line, 
                copied 
         FROM   phrase_longtext_orc_orc 
         WHERE  primarykey IS NOT NULL 
         GROUP  BY system, 
                   `function`, 
                   loglockmod, 
                   extinfo, 
                   primarykey,

为您的 subquery 保留别名，并在创建视图语句中您有 extra column inserted 呈现在您的选择查询中不存在（我已删除下面查询中的额外列）。
