【问题描述】：
我需要根据布尔值在where子句中创建一个条件。
如果为 true，则当最终值与预期值不同时（ConfirmedVolume > ExpectedVolume 等）我选择行，如果为 false，我选择所有内容。
我查看了一些链接，但无法将这个想法应用于我的查询。
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
我想在哪里做类似的事情：
WHERE {RouteStop}.[Id] = @RouteStopId
AND ({SitePlanningArea}.[PlanningAreaId] = @PlanningAreaId OR @PlanningAreaId = 0)
AND IF boolean = true
ConfirmedVolume > ExpectedValue
AND ConfirmedQuantity > ExpectedQuantity

您确定您使用的是 Oracle 吗？那些可怕的方括号看起来更像微软的 T-SQL
-
我正在使用 Outsystems。
-
outsystems 不是数据库产品。
-
尝试至少了解它是什么。
-
我明白它是什么——一个编程环境。它不是数据库。但是您的问题是寻求 SQL 语句的帮助，因此您的 IDE 或框架大多是无关紧要的（我假设所有那些无效的花括号都将在运行时被替换）。为了让您获得对您有帮助的答案，您必须告诉我们您正在使用哪种数据库产品。如果您得到一个针对 Oracle 但您使用的是 SQL Server 的答案，这对您没有帮助。这是两种截然不同的产品
