关于这一具体问题：

不要期望理解被查询的数据：它是无关的

请看一下WHERE子句：

SELECT 
    de.DocumentEntryId,
    de.Number,
    currentdev.ToIgnore,
    previousdev.ToIgnore,
    currentdev.DocumentEntryValueId AS CurrentDocumentEntryValueId, 
    SUM(currentper.Value) AS CurrentPaymentRate,
    SUM(currentdevr.ConversionRate) AS CurrentConversionRate,
    MAX(previousdev.DocumentEntryValueId) AS PreviousDocumentEntryValueId,
    SUM(previousper.Value) AS PreviousPaymentRate,
    SUM(previousdevr.ConversionRate) AS PreviousConversionRate
FROM 
    DocumentEntry de
    INNER JOIN PaymentEntry currentpe ON currentpe.PaymentEntryId = de.CurrentPaymentEntryId
    INNER JOIN DocumentEntryValue currentdev ON currentpe.DocumentEntryValueId = currentdev.DocumentEntryValueId
    INNER JOIN DocumentEntryValue previousdev ON previousdev.DocumentEntryId = de.DocumentEntryId
    INNER JOIN PaymentEntryRate currentper ON currentpe.PaymentEntryId = currentper.PaymentEntryId
    INNER JOIN DocumentEntryValueRate currentdevr ON currentdev.DocumentEntryValueId = currentdevr.DocumentEntryValueId
    INNER JOIN PaymentEntry previouspe ON previousdev.DocumentEntryValueId = previouspe.DocumentEntryValueId
    INNER JOIN PaymentEntryRate previousper ON previouspe.PaymentEntryId = previousper.PaymentEntryId
    INNER JOIN DocumentEntryValueRate previousdevr ON previousdevr.DocumentEntryValueId = previousdev.DocumentEntryValueId
WHERE 
    previousdev.DocumentEntryValueId <> currentdev.DocumentEntryValueId
    AND currentdev.ToIgnore <> 1
    AND previousdev.ToIgnore <> 1
    AND currentpe.PaymentId = previouspe.PaymentId
GROUP BY 
    de.DocumentEntryId, 
    de.Number,
    currentdev.ToIgnore,
    previousdev.ToIgnore,
    currentdev.DocumentEntryValueId
ORDER BY DocumentEntryId

AND currentdev.ToIgnore <> 1
AND previousdev.ToIgnore <> 1

这很有帮助，下面是每个表的索引：

以下是使用相等运算符（=0）时估计执行计划的一部分：

有人能解释一下为什么在这种情况下（或者可能在很多情况下），不等式运算符似乎比等式运算符快吗？

我不知道为什么，但我无法发表评论，只能给出答案，因此如果这对您不起作用，请忽略

创建带有“WHERE-ToIgnore=0”的非聚集索引应该可以纠正这个问题

ToIgnore=1与ToIgnore=0的记录计数是多少？我猜ToIngore=1的记录数量要比设置为0的记录数量大得多

我记得不久前，一位Oracle/SQL DBA告诉我，位列不需要and index，因为Microsoft为您解决了这个问题，这可以解释您的问题。但是，我找不到任何支持它的东西，这可能是Oracle的问题，他们认为MS也必须这样做。

您是否比较了两个查询的实际执行计划以寻找线索？请记住，位字段有三种状态，而不是两种。您是否使用索引？如果是这样的话，您是否可以在上面查询的表上发布任何相关索引？在SSMS中，在表的树状视图中，有一个“Indexes”文件夹。如果展开它，您将看到所有索引（如果有的话）。假设只有几个，可以右键单击索引，选择“脚本索引为”>“创建到”>“剪贴板”；然后将生成的SQL作为编辑粘贴到您的问题中（只包括主索引定义）。@SteveHémond:令人担忧的是，没有包含
ToIgnore
列的索引。在我看来，应该有一个将
DocumentEntryValue.DocumentEntryValueId
和
dcomentryvalue.ToIgnore
组合在一起的。如果您查看有效查询的估计或实际查询计划，它是否建议任何其他缺少的索引？（将在执行计划顶部显示为绿色文本。）您是否比较了两个查询的实际执行计划以寻找线索？请记住，位字段有三种状态，而不是两种。您是否使用索引？如果是这样的话，您是否可以在上面查询的表上发布任何相关索引？在SSMS中，在表的树状视图中，有一个“Indexes”文件夹。如果展开它，您将看到所有索引（如果有的话）。假设只有几个，可以右键单击索引，选择“脚本索引为”>“创建到”>“剪贴板”；然后将生成的SQL作为编辑粘贴到您的问题中（只包括主索引定义）。@SteveHémond:令人担忧的是，没有包含
