[英]CAML “NOT IN” query
Is there a way to do something like "NOT IN" behavior in SharePoint 2010? 有没有办法在SharePoint 2010中执行“NOT IN”行为? I can easily implement IN behavior like that:
我可以像这样轻松实现IN行为:
<Where>
<In>
<FieldRef Name="ID"/>
<Values>
<Value Type="Counter">1</Value>
<Value Type="Counter">2</Value>
<Value Type="Counter">3</Value>
<Value Type="Counter">4</Value>
<Value Type="Counter">5</Value>
</Values>
</In>
</Where>
But is there a way to select all the values that DOES NOT IN Values enumeration? 但有没有办法选择所有值不在值列举?
Here is the USE CASE: I have a Lookup field with AllowMultipleValues = true, and I need to get all items from LookupList, which are not included into Lookup field 这是USE CASE:我有一个带有AllowMultipleValues = true的Lookup字段,我需要从LookupList获取所有项目,这些项目不包含在Lookup字段中
Thanks in advance! 提前致谢!
Starting from SharePoint 2010, there's the NotIncludes
element that might work for you. 从SharePoint 2010开始,可能有适合您的
NotIncludes
元素。 From MSDN: 来自MSDN:
If the specified field is a Lookup field that allows multiple values, specifies that the Value element is excluded from the list item for the field that is specified by the FieldRef element.
如果指定的字段是允许多个值的查找字段,则指定从FieldRef元素指定的字段的列表项中排除Value元素。
Template: 模板:
<NotIncludes>
<FieldRef Name="Field_Name" />
<Value Type="Field_Type" />
<XML />
</NotIncludes>
To get the opposite behavior of 'In', you have to make a nested 'Neq' query. 要获得“In”的相反行为,您必须进行嵌套的“Neq”查询。 'NotIncludes' could be substituted for or combined with 'Neq' if you are dealing with a Lookup Field with multiple values .
如果您正在处理具有多个值的查找字段,则“NotIncludes”可以替换为“Neq”或与“Neq”组合使用。
<Query>
<Where>
<And>
<And>
<Neq>
<FieldRef Name="ID" /><Value Type="Counter">5</Value>
</Neq>
<Neq>
<FieldRef Name="ID" /><Value Type="Counter">13</Value>
</Neq>
</And>
<And>
<NotIncludes>
<FieldRef Name="children" /><Value Type="Lookup">20</Value>
</NotIncludes>
<NotIncludes>
<FieldRef Name="children" /><Value Type="Lookup">32</Value>
</NotIncludes>
</And>
</And>
</Where>
</Query>
If you want more variables then more nesting needs to be done. 如果您想要更多变量,则需要进行更多嵌套。 Have fun.
玩得开心。
I think the Not equal option would be the best way to build this CAML query 我认为不等于选项将是构建此CAML查询的最佳方式
Maybe this (didn't test this, so bear with me) 也许这个(没试过这个,所以请耐心等待)
<Query>
<Where>
<And>
<Neq>
<FieldRef Name="ID" /><Value Type="Counter">1</Value>
</Neq>
<Neq>
<FieldRef Name="ID" /><Value Type="Counter">2</Value>
</Neq>
<Neq>
<FieldRef Name="ID" /><Value Type="Counter">3</Value>
</Neq>
</And>
</Where>
</Query>
You should have a look at the available Comparison Operators 您应该查看可用的比较运算符
The closest I've come is to use <NotIncludes></NotIncludes>
, but for some reason is does not work the same way as <In></In>
. 我最接近的是使用
<NotIncludes></NotIncludes>
,但由于某种原因,它与<In></In>
。 In <In>
I can use <Values>
. 在
<In>
我可以使用<Values>
。 With <NotIncludes>
it looks like you can only specify one value. 使用
<NotIncludes>
看起来您只能指定一个值。 The rest will have to be <Or>
ed in, similar to <Neq>
. 其余部分必须
<Or>
编入,类似于<Neq>
。
