我有一个 SQL 查询需要从 7 月 1 日到 8 月 20 日进行优化和循环cp_ex_dt字段。现在我必须为每个日期单独运行并将输出保存在 csv 文件中。有人可以建议我运行它的最佳方法吗？有什么我可以在快速 sql 中使用的东西吗？请注意我的公司不允许我运行 java。

谢谢你调查它。

除了与您的“D”别名相关的“REG”和“SPECIAL”条目之外，您的前两部分联合查询几乎相同。这两个可以通过使用第一个选择来简化，但在以下位置更改区域：

  AND D.S_I_INST(+) = 45 
  AND (
         (     A.CP_REA = 'REG'
           AND D.CP_REA(+) IN ('final','REG','REG cash','partnership dst')
         )
         OR
         (    A.CP_REA = 'SPECIAL'
          AND D.CP_REA(+) IN ('special cash','SPECIAL')
         )
       )

并将完全删除针对“A”表的第一个联合。

您的第三个和第四个联合是相似的，但从您的“A”表为 NULL 的“D”表中提取。将它的 where 子句更改为：

  AND A.S_I_INST(+) = 46 
  AND (
        (     A.CP_REA(+) = 'REG'
          AND D.CP_REA IN ('final','REG','REG cash','partnership dst')
        )
        OR
        (     A.CP_REA(+) = 'SPECIAL'
          AND D.CP_REA IN ('special cash','SPECIAL')
        )
      )

所以这应该导致简化

select fields
   from your "A" based query
union
select fields
   from your "D" based query

此外，它可能会被进一步简化，但在没有看到更多数据上下文的情况下，“A”和“D”表的自连接可能会消除联合，但不确定当前是否存在。

根据反馈进行编辑 不是 Oracle 专家，但确实认识到 (+) 是左连接语法的指示符......并且没有 oracle 可以尝试使用实际的示例表和数据，我只能提供以下轻微调整。看来您正在处理每当“A”是“REG”时，“D.CP_REA”的唯一可能性就是提供的 IN 列表，并且永远不会有“A.CP_CREA”作为“REG”而“D”方有“特殊现金”或“特殊”……反之亦然。如果是这样，也许你可以适应

  AND D.S_I_INST(+) = 45 
  AND A.CP_REA IN ( 'REG', 'SPECIAL' )
  AND D.CP_REA(+) IN ( 'final','REG','REG cash','partnership dst', 
                       'special cash','SPECIAL')
