Hive创建表错误。

你能帮我克服当我尝试创建下表时遇到的错误吗？Hive创建表错误。

感谢

CREATE TABLE RANGE_FT (HOSP_VAR STRING, RANGE INT) 
AS 
      SELECT 'EMR' ,MAX(emr_avg_score) - MIN(emr_avg_score) from JOIN9 
    UNION SELECT 'SCI' ,MAX(sci_avg_score) - MIN(sci_avg_score) from JOIN9 
    UNION SELECT 'ASTH' ,MAX(asth_avg_score) - MIN(asth_avg_score) from JOIN9 
    UNION SELECT 'HF' ,MAX(hf_avg_score) - MIN(hf_avg_score) from JOIN9 
    UNION SELECT 'SC' ,MAX(sc_avg_score) - MIN(sc_avg_score) from JOIN9 
    UNION SELECT 'PNEU' ,MAX(pneu_avg_score) - MIN(pneu_avg_score) from JOIN9 
    UNION SELECT 'PREV' ,MAX(prev_avg_score) - MIN(prev_avg_score) from JOIN9 
    UNION SELECT 'BC' ,MAX(BC_avg_score) - MIN(BC_avg_score) from JOIN9 
    UNION SELECT 'HEART' ,MAX(heart_avg_score) - MIN(heart_avg_score) from JOIN9 
    UNION SELECT 'PREG' ,MAX(preg_avg_score) - MIN(preg_avg_score) from JOIN9 
;

线7：6 ALL在 'SELECT'

试试SET NOCOUNT查询 –

之前，请用文本替换图像（粘贴后，选中它，然后按CTRL + K对其进行格式化代码） –

嗨辛格，谢谢你你的帮助。你可以更加关于如何设置nocount吗？我的意思是我应该把这个命令放在哪里。我的代码是：DROP TABLE RANGE_FT; CREATE TABLE RANGE_FT （HOSP_VAR STRING， RANGE INT） AS SELECT 'EMR'，MAX（emr_avg_score） - 从JOIN9 MIN（sci_avg_score） - MIN（emr_avg_score）从JOIN9 UNION SELECT 'SCI'，MAX（sci_avg_score）来自JOIN9的UNION SELECT'ASTH'，MAX（asth_avg_score）-min（asth_avg_score）来自JOIN9的UNION SELECT'HF'，MAX（hf_avg_score）-min（hf_avg_score） –

UNION丢失不被你的蜂巢版本支持（而这也不是你所需要的这里）。
改为使用UNION ALL。 https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Union
UNION [ALL]需要双方都有相同的模式。
在Hive中，与其他SQL方言不同，不仅类型应该相似，而且列别名也应该相似。 https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Union
您不能在创建语句中列出列。
将相关别名添加到SELECT子句。

这是您的查询

CREATE TABLE RANGE_FT 
AS 
       SELECT 'EMR' as HOSP_VAR ,MAX (emr_avg_score) - MIN (emr_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'SCI' as HOSP_VAR ,MAX (sci_avg_score) - MIN (sci_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'ASTH' as HOSP_VAR ,MAX (asth_avg_score) - MIN (asth_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'HF' as HOSP_VAR ,MAX (hf_avg_score) - MIN (hf_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'SC' as HOSP_VAR ,MAX (sc_avg_score) - MIN (sc_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'PNEU' as HOSP_VAR ,MAX (pneu_avg_score) - MIN (pneu_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'PREV' as HOSP_VAR ,MAX (prev_avg_score) - MIN (prev_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'BC' as HOSP_VAR ,MAX (BC_avg_score) - MIN (BC_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'HEART' as HOSP_VAR ,MAX (heart_avg_score) - MIN (heart_avg_score) as RANGE from JOIN9 
    UNION ALL SELECT 'PREG' as HOSP_VAR ,MAX (preg_avg_score) - MIN (preg_avg_score) as RANGE from JOIN9 
;

的固定版本，而这里是只有一个SELECT

create table RANGE_FT 
as 
select inline 
     (
      array 
      (
       struct ('EMR' ,MAX (emr_avg_score) - MIN (emr_avg_score) ) 
       ,struct ('SCI' ,MAX (sci_avg_score) - MIN (sci_avg_score) ) 
       ,struct ('ASTH' ,MAX (asth_avg_score) - MIN (asth_avg_score)) 
       ,struct ('HF' ,MAX (hf_avg_score) - MIN (hf_avg_score) ) 
       ,struct ('SC' ,MAX (sc_avg_score) - MIN (sc_avg_score) ) 
       ,struct ('PNEU' ,MAX (pneu_avg_score) - MIN (pneu_avg_score)) 
       ,struct ('PREV' ,MAX (prev_avg_score) - MIN (prev_avg_score)) 
       ,struct ('BC' ,MAX (BC_avg_score) - MIN (BC_avg_score) ) 
       ,struct ('HEART' ,MAX (heart_avg_score) - MIN (heart_avg_score)) 
       ,struct ('PREG' ,MAX (preg_avg_score) - MIN (preg_avg_score)) 
      ) 
     ) as (HOSP_VAR,RANGE) 

from JOIN9  
;

我得到了一个错误失败：SemanticException [错误10065]：CREATE TABLE AS SELECT命令无法指定目标表的列列表 –

我只是将它发布到文本中。非常感谢您的帮助Dudu –

Hi Dudu，你能告诉我你如何创建这张桌子的魔术？非常感谢你的回复。 –

这将工作的替代解决方案正如Dudu所提到的，你不能给列名称w hile用select创建。您可以使用Union，但性能明智的UNION ALL更好。根据您的用例

CREATE TABLE RANGE_FT 
AS 
      SELECT 'EMR' AS HOSP_VAR ,MAX(emr_avg_score) - MIN(emr_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'SCI' AS HOSP_VAR ,MAX(sci_avg_score) - MIN(sci_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'ASTH' AS HOSP_VAR ,MAX(asth_avg_score) - MIN(asth_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'HF' AS HOSP_VAR ,MAX(hf_avg_score) - MIN(hf_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'SC' AS HOSP_VAR ,MAX(sc_avg_score) - MIN(sc_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'PNEU' AS HOSP_VAR ,MAX(pneu_avg_score) - MIN(pneu_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'PREV' AS HOSP_VAR ,MAX(prev_avg_score) - MIN(prev_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'BC' AS HOSP_VAR ,MAX(BC_avg_score) - MIN(BC_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'HEART' AS HOSP_VAR ,MAX(heart_avg_score) - MIN(heart_avg_score) AS `RANGE` from JOIN9 
    UNION SELECT 'PREG' AS HOSP_VAR ,MAX(preg_avg_score) - MIN(preg_avg_score) AS `RANGE` from JOIN9 
;

嗨阿希什，谢谢你的帮助。但即使我删除列名称并运行代码，错误仍然显示像这样失败：ParseException行4:12在'SELECT'在''附近缺少ALL' 行5：12在'SELECT'附近'' –

@QingZhang请别名列名并将Range列放入反斜杠中' –
