【问题描述】：

我正在尝试将数据从 xml 文件插入到临时表中，问题是我可以一次输入一行数据：

DECLARE @tblCountry TABLE
(
CountryCode nvarchar(5),
CountryName nvarchar(50)
)
INSERT INTO @tblCountry(CountryCode, CountryName)
SELECT --DISTINCT
x.v.value('(/countries/country/@code)[1]','VARCHAR(5)'),
x.v.value('(/countries/country/text())[1]','VARCHAR(50)')
FROM @countryXML.nodes('/countries/country') x(v)
SELECT CountryCode, CountryName FROM @tblCountry

但是当我试图把它放在一个循环中时，我无法让它工作：

create proc spcountry
@count int
AS
BEGIN
DECLARE @countryXML XML
SET @countryXML = '<countries>
<country code="AF" iso="4">Afghanistan</country>
<country code="ZW" iso="716">Zimbabwe</country>
</countries>'
DECLARE @tblCountry TABLE
(
CountryCode nvarchar(5),
CountryName nvarchar(50)
)
SET @count = 1
WHILE (@count < 238)
BEGIN

INSERT INTO @tblCountry(CountryCode, CountryName)
SELECT --DISTINCT
x.v.value('(/countries/country/@code)[sql:variable("@count")]','VARCHAR(5)'),
x.v.value('(/countries/country/text())[[sql:variable("@count")]]','VARCHAR(50)')
FROM @countryXML.nodes('/countries/country') x(v)
set @count = @count + 1
END
END
SELECT CountryCode, CountryName FROM @tblCountry

我正在关注此链接的解决方案： XML data type method “value” must be a string literal

【问题讨论】：

您是否尝试使用循环来获取顶部的@count 行？
不，我有那么多行，所以我数了数并运行到 238

【解决方案1】：

create proc spcountry @count int
AS
    declare @countryXML XML;
    declare @tblCountry TABLE
    (
        CountryCode nvarchar(5),
        CountryName nvarchar(50)
    );
begin

    SET @countryXML = '<countries>
    <country code="AF" iso="4">Afghanistan</country>
    <country code="ZW" iso="716">Zimbabwe</country>
    </countries>';


    INSERT INTO @tblCountry(CountryCode, CountryName)
    SELECT TOP(@count)
        x.v.value('@code','VARCHAR(50)'),
        x.v.value('.','VARCHAR(50)')
    FROM @countryXML.nodes('/countries/country') x(v)
    SELECT CountryCode, CountryName 
    FROM @tblCountry;

end
go

-- sample call
-- exec spcountry 2
