Oracle Where Case

Question

我需要根据布尔值在where子句中创建一个条件。

如果为true，则在最终值与预期值（ConfirmedVolume> ExpectedVolume等）不同时选择行（如果为false）我选择所有内容。

我查看了一些链接，但无法将ideia应用于我的查询。

例如。

码：

SELECT  RouteId,
        Id,
        RouteStatusId,
        Address,
        Latitude,
        Longitude,

        ConfirmedQty,
        FinalQty,
        ExpectedWeight,
        ConfirmedWeight,
        FinalWeight,
        ExpectedVolume,
        ConfirmedVolume,
        FinalVolume,
        Comm,
        MAX(EndTime) - MAX(StartTime),
        MAX(StartTime),
        MAX(EndTime),
        WaitTime,
        MAX(CAST(EndTime AS DATE)),
        UOM,
        BPName

    CASE WHEN {GPS}.[EventTypeId] = @RouteStopStarted

我想在以下地方做类似的事情：

WHERE {RouteStop}.[Id] = @RouteStopId
      AND ({SitePlanningArea}.[PlanningAreaId] = @PlanningAreaId OR @PlanningAreaId = 0)
      AND IF boolean = true
          ConfirmedVolume > ExpectedValue
      AND ConfirmedQuantity > ExpectedQuantity

Answer 1

在伪代码中推理，您可能需要编辑

IF boolean = true
          ConfirmedVolume > ExpectedValue

变成类似的东西

( (boolean = true and ConfirmedVolume > ExpectedValue) OR (boolean = false) )
