Question

我有以下XML

    <?xml version="1.0"?>
    <ArrayOfInt xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="id">
        <int>984026</int>
        <int>1005222</int>
    </ArrayOfInt>

我将它传递给带有XML参数的存储过程。

我想从xml doc

返回id在int节点中的所有行

    SELECT * FROM
    MyTable
    WHERE
    MyTable.Id IN @XMLDoc.value('(.)[1]', 'int')

这只适用于我在xml中发送一个int

    <?xml version="1.0"?>
    <ArrayOfInt xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="id">
        <int>984026</int>
    </ArrayOfInt>

但是如果我用两个int节点运行它，sql连接节点

The conversion of the nvarchar value '9840261005222' overflowed an int column.

    declare @XMLDoc xml = '<?xml version="1.0"?>
           <ArrayOfInt xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="id">
               <int>984026</int>
               <int>1005222</int>
           </ArrayOfInt>'

    ;WITH XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema-instance' as xsi ,
                'id' as ns2,
                DEFAULT 'id')
    SELECT MT.* 
    FROM MyTable
    join @XMLDoc.nodes('/ArrayOfInt/int') T(z) 
    on MT.ID = T.z.value('.','int')

检查xml节点中是否存在值
