Question

我正在尝试在以下代码中在oracle 11g中创建一个视图但得到错误说命令没有正确结束，任何人都在我的位置指向正确的方向或纠正我。

CREATE

Answer 1

首先，我简化了您提交的查询。老实说，就像K Sly，Zak和APC所说，你的格式很糟糕。

这让我来到这里：

CREATE OR replace FORCE editionable VIEW "GINSOBADEV_DW"."V_PSI" ( "PARENT_PI_NUMBER","REQUEST_NUM","PI_CANDIDATE_NUM","PSI_SCORE","PSI_Xmation","PSI_BAND" ) AS
SELECT dd.request_num, 
       dd.pi_candidate_num, 
       dd.psi_score, 
       dd.psi_xmation, 
       (CASE 
              WHEN dd.psi_xmation <=      -0.880927 THEN 1 
              WHEN dd.psi_xmation BETWEEN -0.880926 AND    -0.063391 THEN 2 
              WHEN dd.psi_xmation BETWEEN -0.063390 AND    0.706751 THEN 3 
              WHEN dd.psi_xmation >= 0.706752 THEN 4 
       END) AS psi_band 
  FROM (SELECT bb.request_num, 
               bb.pi_candidate_num, 
               bb.request_last_modified_dt, 
               coalesce (bb.gco_ad_knowledge_test_score, bb.psi_overall_score)                        AS psi_score,
               ((coalesce(bb.gco_ad_knowledge_test_score, bb.psi_overall_score) -39.035024)/8.439997) AS psi_xmation
          FROM (SELECT cc.arank, 
                          cc.parent_pi_number, 
                          cc.request_num, 
                          cc.pi_candidate_num, 
                          cc.psi_overall_score, 
                          cc.gco_ad_knowledge_test_score, 
                          cc.request_last_modified_dt 
                     FROM (SELECT row_number() over (PARTITION BY pi_candidate_num ORDER BY request_last_modified_dt DESC, request_num ASC) arank ,
                                  parent_pi_number, 
                                  request_num, 
                                  pi_candidate_num, 
                                  psi_overall_score, 
                                  gco_ad_knowledge_test_score, 
                                  request_last_modified_dt 
                             FROM wc_application_event_f 
                            WHERE (psi_overall_score IS NOT NULL OR gco_ad_knowledge_test_score IS NOT NULL)) cc 
                    WHERE cc.arank =1)bb)dd;

我觉得这个查询对于你想要达到的目标来说仍然太复杂了。更不用说，你有进入的参数没有在任何地方使用。

所以我简化了这个查询：

CREATE OR replace FORCE  VIEW "V_PSI" AS
with calculated_values as
         (select request_num,
                 pi_candidate_num, 
                 coalesce (gco_ad_knowledge_test_score, psi_overall_score) AS psi_score,
                 ((coalesce(gco_ad_knowledge_test_score, psi_overall_score) -39.035024)/8.439997) AS psi_xmation,
                 row_number() over (PARTITION BY pi_candidate_num ORDER BY request_last_modified_dt DESC, request_num ASC) arank
            from wc_application_event_f
           where psi_overall_score IS NOT NULL OR gco_ad_knowledge_test_score IS NOT NULL)
SELECT request_num, 
       pi_candidate_num, 
       psi_score, 
       psi_xmation, 
       (CASE 
              WHEN psi_xmation <=      -0.880927 THEN 1 
              WHEN psi_xmation BETWEEN -0.880926 AND    -0.063391 THEN 2 
              WHEN psi_xmation BETWEEN -0.063390 AND    0.706751 THEN 3 
              WHEN psi_xmation >= 0.706752 THEN 4 
       END) AS psi_band 
  FROM calculated_values
  where arank = 1;

然后当我添加可编辑条款时，我遇到了各种各样的麻烦（顺便说一下，实际上是“正在编辑”）

首先，Oracle不喜欢“with”声明;它生成了一个ORA-00922，所以我再次将它移动到子查询中。

然后它抱怨ORA-00936这是一个缺失的陈述。

长话短说，我经历了几次迭代，并且不能在视图中执行查询。我认为您需要提供更多背景信息，说明您在这里使用可编辑视图的原因。另外，为什么强迫结果限于第一个？

您可以参考的资源：

Answer 2

我想这取决于你如何实现这一点。如果在SQL * Plus中运行它，它会将双新行字符作为新语句读取。

尝试删除换行符，以便每行不超过一个换行符。删除评论也会有所帮助。 EG：

CREATE OR REPLACE FORCE EDITIONABLE VIEW "GINSOBADEV_DW"."V_PSI" (
"PARENT_PI_NUMBER","REQUEST_NUM","PI_CANDIDATE_NUM","PSI_SCORE","PSI_Xmation","PSI_BAND"
)  AS  SELECT  REQUEST_NUM,PI_CANDIDATE_NUM,PSI_SCORE,PSI_Xmation,
(CASE  WHEN DD.PSI_Xmation <= -0.880927 THEN 1 WHEN DD.PSI_Xmation
BETWEEN -0.880926 AND -0.063391 THEN 2 WHEN DD.PSI_Xmation BETWEEN
-0.063390 AND  0.706751 THEN 3 WHEN DD.PSI_Xmation >= 0.706752 THEN 4  END ) AS PSI_BAND
FROM  ( SELECT
REQUEST_NUM,PI_CANDIDATE_NUM,REQUEST_LAST_MODIFIED_DT, COALESCE
(GCO_AD_KNOWLEDGE_TEST_SCORE,PSI_OVERALL_SCORE) AS PSI_SCORE,
(COALESCE(GCO_AD_KNOWLEDGE_TEST_SCORE, PSI_OVERALL_SCORE)
-39.035024)/8.439997 AS PSI_Xmation
FROM(
SELECT
ARANk,PARENT_PI_NUMBER,REQUEST_NUM,PI_CANDIDATE_NUM,PSI_OVERALL_SCORE,GCO_AD_KNOWLEDGE_TEST_SCORE,REQUEST_LAST_MODIFIED_DT
FrOM( SELECT     ROW_NUMBER() OVER (PARTITION  BY PI_CANDIDATE_NUM
ORDER BY REQUEST_LAST_MODIFIED_DT DESC,REQUEST_NUM  ) ARANK  
,PARENT_PI_NUMBER,REQUEST_NUM,PI_CANDIDATE_NUM,PSI_OVERALL_SCORE,GCO_AD_KNOWLEDGE_TEST_SCORE,REQUEST_LAST_MODIFIED_DT
FROM    WC_APPLICATION_EVENT_F
WHERE (PSI_OVERALL_SCORE IS NOT NULL OR GCO_AD_KNOWLEDGE_TEST_SCORE
IS NOT Null)
     ) CC   WHERE  ARANK =1 ) BB )DD;
