Question

SELECT /*+ PARALLEL(aae,4) */ DISTINCT nvl(aae.voucher_group_id,-1)  voucher_group_id,
                           aae.nominal_transaction_amount unit_price,
                           aae.original_currency_type currency_type,
                           aae.segmentation_id
             FROM air_account_events aae
            WHERE aae.time_hour_id >= m_start_thid
              AND aae.time_hour_id < m_end_thid
              AND aae.nominal_transaction_amount is not null 
           MINUS
           SELECT vg.voucher_group_id,
                  vg.unit_price,
                  vg.currency_type,
                  vg.segmentation_id
             FROM wh_voucher_groups_dim vg) ahm
    ON (whm.voucher_group_id = ahm.voucher_group_id AND whm.unit_price = ahm.unit_price 
    AND whm.currency_type = ahm.currency_type AND whm.segmentation_id=ahm.segmentation_id) ahm

当我运行以下PL / SQL时，出现错误

         FROM wh_voucher_groups_dim vg) ahm
                                      *

第14行的错误： ORA-00933：SQL命令未正确结束

你可以指导哪里出错，还请指导改变

Answer 1

您在此行中缺少JOIN条件：

FROM wh_voucher_groups_dim vg) ahm
   JOIN ???????
   ON (whm.voucher_group_id ....

Answer 2

编辑：根据您的评论 你可能正在寻找这个..？您需要在大括号中包含完整的内部查询，为其指定别名，然后将其连接到另一个表。无需使用“使用”。

select * from wh_voucher_groups_dim whm,
( SELECT /*+ PARALLEL(aae,4) */ 
         DISTINCT nvl(aae.voucher_group_id,-1)  voucher_group_id,
                           aae.nominal_transaction_amount unit_price,
                           aae.original_currency_type currency_type,
                           aae.segmentation_id
             FROM air_account_events aae
            WHERE aae.time_hour_id >= m_start_thid
              AND aae.time_hour_id < m_end_thid
              AND aae.nominal_transaction_amount is not null 
           MINUS
           SELECT vg.voucher_group_id,
                  vg.unit_price,
                  vg.currency_type,
                  vg.segmentation_id
             FROM wh_voucher_groups_dim vg
 ) ahm
    WHERE  (whm.voucher_group_id = ahm.voucher_group_id AND 
            whm.unit_price = ahm.unit_price AND
            whm.currency_type = ahm.currency_type AND 
            whm.segmentation_id=ahm.segmentation_id)

您之前可能有ANSI连接语法，并在第二个查询中删除了该部分？

SELECT vg.voucher_group_id,
                  vg.unit_price,
                  vg.currency_type,
                  vg.segmentation_id
             FROM wh_voucher_groups_dim vg) ahm
    ON (whm.voucher_group_id = ahm.voucher_group_id AND 
        whm.unit_price = ahm.unit_price AND
        whm.currency_type = ahm.currency_type AND  
        whm.segmentation_id=ahm.segmentation_id) ahm

FROM wh_voucher_groups_dim vg）啊 ON（whm.voucher_group_id = ahm.voucher_group_id AND

这里是否有另一个表别名？

Answer 3

要使用ON关键字，您需要在它之前加入。我在下面添加了JOIN关键字。您需要自己决定是否需要标准连接，外部，内部等。

             FROM wh_voucher_groups_dim vg) ahm JOIN <table>
    ON (whm.voucher_group_id = ahm.voucher_group_id AND whm.unit_price = ahm.unit_price 
    AND whm.currency_type = ahm.currency_type AND whm.segmentation_id=ahm.segmentation_id) ahm

Answer 4

我的猜测是，这是一个更大的查询的一部分，并以某种方式删除了开始部分：

SELECT ...                  --- missing part
FROM ...                    --- missing part
    sometable whm           --- missing part
        SOME JOIN           --- missing part
    (                       --- missing part

      SELECT /*+ PARALLEL(aae,4) */ DISTINCT ...
      ...
      FROM wh_voucher_groups_dim vg
    ) ahm
      ON ( whm.voucher_group_id = ahm.voucher_group_id 
       AND whm.unit_price = ahm.unit_price 
       AND whm.currency_type = ahm.currency_type 
       AND whm.segmentation_id=ahm.segmentation_id
         )

SQL命令未正确结束
