Hive創建表錯誤。

你能幫我克服當我嘗試創建下表時遇到的錯誤嗎？Hive創建表錯誤。

感謝

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 
;

線7：6 ALL在 'SELECT'

試試SET NOCOUNT查詢 –

之前，請用文本替換圖像（粘貼後，選中它，然後按CTRL + K對其進行格式化代碼） –

嗨辛格，謝謝你你的幫助。你可以更加關於如何設置nocount嗎？我的意思是我應該把這個命令放在哪裏。我的代碼是：DROP TABLE RANGE_FT; CREATE TABLE RANGE_FT （HOSP_VAR STRING， RANGE INT） AS SELECT 'EMR'，MAX（emr_avg_score） - 從JOIN9 MIN（sci_avg_score） - MIN（emr_avg_score）從JOIN9 UNION SELECT 'SCI'，MAX（sci_avg_score）來自JOIN9的UNION SELECT'ASTH'，MAX（asth_avg_score）-min（asth_avg_score）來自JOIN9的UNION SELECT'HF'，MAX（hf_avg_score）-min（hf_avg_score） –

UNION丟失不被你的蜂巢版本支持（而這也不是你所需要的這裏）。
改爲使用UNION ALL。 https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Union
UNION [ALL]需要雙方都有相同的模式。
在Hive中，與其他SQL方言不同，不僅類型應該相似，而且列別名也應該相似。 https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Union
您不能在創建語句中列出列。
將相關別名添加到SELECT子句。

這是您的查詢

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，而這裏是只有一個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  
;

我得到了一個錯誤失敗：SemanticException [錯誤10065]：CREATE TABLE AS SELECT命令無法指定目標表的列列表 –

我只是將它發佈到文本中。非常感謝您的幫助Dudu –

Hi Dudu，你能告訴我你如何創建這張桌子的魔術？非常感謝你的回覆。 –

這將工作的替代解決方案正如Dudu所提到的，你不能給列名稱w hile用select創建。您可以使用Union，但性能明智的UNION ALL更好。根據您的用例

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，謝謝你的幫助。但即使我刪除列名稱並運行代碼，錯誤仍然顯示像這樣失敗：ParseException行4:12在'SELECT'在''附近缺少ALL' 行5：12在'SELECT'附近'' –

@QingZhang請別名列名並將Range列放入反斜槓中' –
