搜索所有節點的xml列

Question

我正在尋找一種方法來搜索sql xml列中的所有節點。

舉例來說，如果我有以下XML

<ArrayOfEntityPropertyOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <EntityPropertyOfString> 
    <Name>User Label 1</Name> 
    <Value>TX 12107210</Value> 
    </EntityPropertyOfString> 
    <EntityPropertyOfString> 
    <Name>User Label 2</Name> 
    <Value>BONUS $350/DAY</Value> 
    </EntityPropertyOfString> 
    <EntityPropertyOfString> 
    <Name>User Defined Date 9</Name> 
    <Value>11/09/2011</Value> 
    </EntityPropertyOfString> 
</ArrayOfEntityPropertyOfString> 

我如何搜索包含單詞「獎金」全部價值觀

預先感謝您。

declare @xml xml = 
'<ArrayOfEntityPropertyOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
<EntityPropertyOfString> 
    <Name>User Label 1</Name> 
    <Value>TX 12107210</Value> 
</EntityPropertyOfString> 
<EntityPropertyOfString> 
<Name>User Label 2</Name> 
<Value>BONUS $350/DAY</Value> 
</EntityPropertyOfString> 
<EntityPropertyOfString> 
<Name>User Defined Date 9</Name> 
<Value>11/09/2011</Value> 
</EntityPropertyOfString> 
</ArrayOfEntityPropertyOfString>' 

select T.N.value('local-name(.)', 'nvarchar(max)') as NodeName, 
     T.N.value('text()[1]', 'nvarchar(max)') as NodeValue 
from @xml.nodes('//*') as T(N) 
where T.N.value('text()[1]', 'nvarchar(max)') like '%bonus%' 

結果：

NodeName    NodeValue 
-------------------- -------------------- 
Value    BONUS $350/DAY 

對於表它可能看起來像這樣：

declare @T table (ID int identity primary key, XMLCol xml) 

declare @xml xml = 
'<ArrayOfEntityPropertyOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <EntityPropertyOfString> 
    <Name>User Label 1</Name> 
    <Value>TX 12107210</Value> 
    </EntityPropertyOfString> 
    <EntityPropertyOfString> 
    <Name>User Label 2</Name> 
    <Value>BONUS $350/DAY</Value> 
    </EntityPropertyOfString> 
    <EntityPropertyOfString> 
    <Name>User Defined Date 9</Name> 
    <Value>11/09/2011</Value> 
    </EntityPropertyOfString> 
</ArrayOfEntityPropertyOfString>' 

insert into @T values (@xml) 
insert into @T values (@xml) 

select T1.ID, 
     T2.N.value('local-name(.)', 'nvarchar(max)') as NodeName, 
     T2.N.value('text()[1]', 'nvarchar(max)') as NodeValue 
from @T as T1 
    cross apply T1.XMLCol.nodes('//*') as T2(N) 
where T2.N.value('text()[1]', 'nvarchar(max)') like '%bonus%' 

結果：

ID   NodeName    NodeValue 
----------- -------------------- -------------------- 
1   Value    BONUS $350/DAY 
2   Value    BONUS $350/DAY 

Answer 2

如果你可以作出這樣的獎金將永遠不會在標籤中出現的假設......

SELECT 
    ... 
FROM 
    ... 
WHERE COL_NAME LIKE '%bonus%'
