Oracle案例

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不同时选择行（ConfirmedVolume> ExpectedVolume等），如果为false，则选择所有内容。

我看了一些链接，但无法将想法应用到我的查询中。

例如

Conditional WHERE clause with CASE statement in Oracle

Oracle Conditional where clause

代码：

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

FROM
(
SELECT 
    {RouteStop}.[RouteId] RouteId,
    {RouteStop}.[Id] Id,
    {RouteStop}.[RouteStatusId] RouteStatusId,
    {SiteAddress}.[Address] Address,
    {SiteAddress}.[Latitude] Latitude,
    {SiteAddress}.[Longitude] Longitude,
    SUM({RouteStop_Product}.[ExpectedQty]) ExpectedQty,
    SUM({RouteStop_Product}.[ConfirmedQty]) ConfirmedQty,
    SUM({RouteStop_Product}.[FinalQty]) FinalQty,
    SUM({RouteStop_Product}.[ExpectedWeight]) ExpectedWeight,
    SUM({RouteStop_Product}.[ConfirmedWeight]) ConfirmedWeight,
    SUM({RouteStop_Product}.[FinalWeight]) FinalWeight,
    SUM({RouteStop_Product}.[ExpectedVolume]) ExpectedVolume,
    SUM({RouteStop_Product}.[ConfirmedVolume]) ConfirmedVolume,
    SUM({RouteStop_Product}.[FinalVolume]) FinalVolume,
    {RouteStop}.[Comment] Comm,
    CASE WHEN {GPS}.[EventTypeId] = @RouteStopStarted
         THEN {GPS}.[DateTime] 
         ELSE CAST(NULL AS DATE)
    END StartTime,
    CASE WHEN {GPS}.[EventTypeId] = @RouteStopCompleted 
           OR {GPS}.[EventTypeId] = @RouteStopFailed
         THEN {GPS}.[DateTime]
         ELSE CAST(NULL AS DATE)
    END EndTime,
    {GPS}.[EventTypeId] EventTypeId,
    {RouteStop}.[WaitTime] WaitTime, 
    {Order}.[UOM] UOM,
    {BusinessPartner}.[CardName] BPName
FROM {RouteStop}
LEFT JOIN {RouteStop_Product} ON {RouteStop}.[Id]              = {RouteStop_Product}.[RouteStopId]
LEFT JOIN {GPS}               ON {RouteStop}.[Id]              = {GPS}.[RouteStopID]
LEFT JOIN {SiteAddress}       ON {RouteStop}.[SiteAddress]     = {SiteAddress}.[Id]
LEFT JOIN {BusinessPartner} ON {SiteAddress}.[CardCode] = {BusinessPartner}.[Id]
LEFT JOIN {Order}             ON {RouteStop_Product}.[OrderId] = {Order}.[Id]
LEFT JOIN {SitePlanningArea}  ON {SiteAddress}.[Id]            = {SitePlanningArea}.[SiteAddressId]
WHERE {RouteStop}.[Id] = @RouteStopId
      AND ({SitePlanningArea}.[PlanningAreaId] = @PlanningAreaId OR @PlanningAreaId = 0)
GROUP BY {RouteStop}.[RouteId],
         {RouteStop}.[Id],
         {RouteStop}.[RouteStatusId],
         {SiteAddress}.[Address],
         {SiteAddress}.[Latitude],
         {SiteAddress}.[Longitude],
         {RouteStop}.[Comment],
         {GPS}.[EventTypeId],
         {GPS}.[DateTime],
         {RouteStop}.[WaitTime],
         {Order}.[UOM],
         {BusinessPartner}.[CardName]
)
GROUP BY RouteId,
        Id,
        RouteStatusId,
        Address,
        Latitude,
        Longitude,
        ExpectedQty,
        ConfirmedQty,
        FinalQty,
        ExpectedWeight,
        ConfirmedWeight,
        FinalWeight,
        ExpectedVolume,
        ConfirmedVolume,
        FinalVolume,
        Comm,
        WaitTime,
        UOM,
        BPName

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

根据伪代码，您可能需要编辑

IF boolean = true
          ConfirmedVolume > ExpectedValue

变成类似

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