Question

下面我列出了一些示例数据和我用来返回搜索信息的程序。我遇到问题，如果我搜索格式，它也返回信息！如果文本在更大的字符串中，我该如何排除？

这是表格：

CREATE TABLE [dbo].[XmlTable](
        [XmlId] [int] IDENTITY(1,1) NOT NULL,
        [XmlDocument] [xml] NOT NULL,
     CONSTRAINT [PK_XmlTable] PRIMARY KEY CLUSTERED 
    (
        [XmlId] ASC
    )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
    ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]


    GO

这是xml

插入声明

INSERT INTO XmlTable(XMLDocument)
SELECT * FROM OPENROWSET(
   BULK 'C:\Users\123\Desktop\Practice.xml',
   SINGLE_BLOB) AS x;

这是程序

    CREATE PROCEDURE [dbo].[GetXmlSearchString]
        @findString NVARCHAR(100)
    AS
    BEGIN

        SET NOCOUNT ON
        SET @findstring = UPPER(@findstring);

    ;WITH XMLNAMESPACES (Default 'http://www.w3.org/2001/XMLSchema' )
    SELECT      
     XmlId,


               CAST(x.value('.' , 'nvarchar(MAX)') As nvarchar(MAX)) AS Value,
                    a.value('(@Settings)[1]', 'NVARCHAR(200)') AS Title,
                    b.value('(@Id)[1]','nvarchar(MAX)') As [Function],
                    d.value('@Number[1]', 'INT') AS TeamNumber,
                    c.value('(@Name)[1]','nvarchar(MAX)') As  Visitor,
                    f.value('(@Name)[1]', 'NVARCHAR(MAX)') As Sender

              --,RANK() OVER 
           --        (PARTITION BY d.value('@Number[1]', 'INT') 
              --      Order By XmlId  DESC) As RANK

        FROM dbo.XmlTable x

        CROSS APPLY XmlDocument.nodes('Doc') As aa(a)
        CROSS APPLY a.nodes('Functions') As bb(b)
        CROSS APPLY b.nodes('*') dd(d) 
        CROSS APPLY d.nodes('Visitors/Visitor') As cc(c)
        CROSS APPLY d.nodes('Senders/Sender') ff(f)
        CROSS APPLY d.nodes('(.//*[contains(upper-case(text()[1]), sql:variable("@findString"))])[1]
        , (.//@*[contains(upper-case(.), sql:variable("@findString"))])[1]') a(x)
--Where a.x.value('.','nvarchar(MAX)') like '%'+@findstring+'%'

        Order By XmlId

            RETURN
        END


        GO

要搜索确切的单词，请添加WHERE子句：

WHERE a.x.value('.','nvarchar(MAX)') like @findstring+' %'
    or a.x.value('.','nvarchar(MAX)') like '% ' + @findstring+' %' 
    or a.x.value('.','nvarchar(MAX)') like '% ' + @findstring 
    or a.x.value('.','nvarchar(MAX)') = @findstring

我找到了一种更优雅的方式here：

Where ' ' + a.x.value('.','nvarchar(MAX)') + ' ' like '% ' + @findstring + ' %'

或者，如果你想在单词之后允许标点符号（比如“格式化”），那么使用这个：

Where ' ' + a.x.value('.','nvarchar(MAX)') + ' ' like '%[^a-z]' + @findstring + '[^a-z]%'
