Sql 仅选择最长日期记录

我有一个非常大的SQL查询：

我的问题是我必须只从这个左连接TB_SMP_PONTO_ORIGEM_区域SPOA或这个左连接TB_SMP_PONTO_Enterga_区域连接中获取最后一个日期，它根据SQL主体中的以下条件：

案例 当S.DT_SAIDA_PONTO_ORIGEM为空时 SPOA.DT_ENTRADA_PONTO 其他的 斯帕·德图·恩塔达·蓬托 以DT_ENTRADA_SUB_ALVO结尾

我尝试将where语句放在select的末尾：

其中SPEA.DT_ENTRADA_PONTO IN select maxpowed.DT_ENTRADA_PONTO FROM TB_SMP_PONTO_ENTREGA_区域 其中，SPE.CD_SMP_PONTO_ENTREGA=SPE.CD_SMP_PONTO_ENTREGA

它会停止多次显示同一条记录的不同日期，但不会显示其他结果

我的结果使用where：

我的结果不带where：

在第二幅图中，我们可以看到一组id为1254190的记录

因此，我的问题是，我如何在忽略日期DT_ENTRADA_PONTO的情况下检索非重复记录，或者获取其最大值

谢谢你们

解决方案：

我只更改了这些加入：

    LEFT JOIN TB_SMP S
        ON S.CD_SMP = TABVEIC.CD_SMP
    LEFT JOIN (SELECT SPOADESC.CD_SMP, SPOADESC.DT_SAIDA_PONTO, SPOADESC.DT_ENTRADA_PONTO
                        FROM (SELECT * FROM TB_SMP_PONTO_ORIGEM_AREA SPOA 
                        WHERE SPOA.DT_ENTRADA_PONTO IN (SELECT MAX(DT_Entrada_ponto) from TB_SMP_PONTO_ENTREGA)
                        ) SPOADESC ) SPOADESC2
        ON SPOADESC2.CD_SMP = TABVEIC.CD_SMP

    LEFT JOIN TB_SMP_PONTO_ENTREGA SPE
        ON SPE.CD_SMP = S.CD_SMP
    LEFT JOIN (SELECT SPEADESC.CD_SMP_PONTO_ENTREGA, SPEADESC.DT_SAIDA_PONTO, SPEADESC.DT_ENTRADA_PONTO
                        FROM (SELECT * FROM TB_SMP_PONTO_ENTREGA_AREA SPEA 
                             WHERE SPEA.DT_ENTRADA_PONTO IN (SELECT MAX(DT_Entrada_ponto) from TB_SMP_PONTO_ENTREGA)
                             ) SPEADESC ) SPEADESC2
        ON SPE.CD_SMP_PONTO_ENTREGA = SPEADESC2.CD_SMP_PONTO_ENTREGA

---

现在它工作了

不确定Oracle语法，但在加入表时，在PK上加入=表的前1个子查询的PK，按日期列降序

下面是我在SQL Server中的操作方法：

LEFT JOIN MyTable t1 ON t1.PK=(
  SELECT TOP 1 PK
  FROM MyTable t2
  WHERE SomeCondition=true
  ORDER BY DateColumn DESC
)

伟大的这个主意太完美了！我改变了一些事情，现在它开始工作了。我将把溶液粘贴在这里。谢谢你
