我正在尝试将几种 XML 格式加载到一个通用表结构中，但其中一个包含以下 XML 数据时遇到问题：

我无法将变量分配给不同部分中的元素。例如元素“名称”出现在“员工”和“雇主”部分中，我无法区分这些部分以将变量分配给列。

LOAD XML local INFILE 'I:/PAYSLIPS37380004.xml'
INTO TABLE test.temp_payslips
    rows identified by '<payslip>'
    (@NINO,
    @number)

SET Payrollrunid=1,
    isLive=1,
    print=0,
    NINumber=@NINO,
    EmployeeNumber=@number;

我尝试在变量前面加上部分（例如@employee.number），但这不起作用。有什么想法吗？

我还需要根据“元素”部分中的数据在子表 (paysliptrans) 中创建记录。我想使用的代码是：

LOAD XML local INFILE 'I:/PAYSLIPS37380004.xml'
INTO TABLE pmdata_test.temp_paysliptrans rows identified by '<elements>'
    (@title,
    @amount,
    @position,
    @rate,
    @units,
    @ytd)

SET PayslipID=(select payslipid from pmdata_test.temp_payslips where EmployeeNumber=@number),
    Name=@title,
    Type="P",
    Total=@amount,
    Rate=@rate,
    Units=@units,
    YTD=@ytd;

但我仍然有同样的问题，因为它不会提取获取 payslipID 数据以填充 paysliptrans.payslipID 字段所需的@number（员工）。

【问题讨论】：

还可以共享表的表结构。temp_payslips 和 temp_paysliptrans... 也许我明白然后希望您尝试从 xml 导入。第二个 IMPORT 查询很清楚您想要从元素标签加载数据..第一个 IMPORT 查询不是很清楚..
我已经为 2 个表添加了 Create SQL。

标签： mysql xml

【解决方案1】：

XML文件的加载可以实现如下：

文件：/path/to/file/PAYSLIPS37380004.xml：

【讨论】：

感谢您的回复。我尝试了第一个选项并进行了检索，但问题是它只能从部分获取数据。我还想从
、、、、和部分获取数据。问题是@name 存在于和部分中，但与 temp_payslips.CompanyName 和 temp_payslips.EmployeeName
相关
当我运行处理 PayslipID 的第二个查询时，我收到以下错误：错误代码：1048。列 'EmployeeNumber' 不能为空
@JamesKnight: 13.2.7 LOAD XML Syntax 功能有限，您可能无法完成所需的一切。
@JamesKnight：你有一个空的EmployeeNumber吗？。
没有。我用 1 替换了 ExtractValue(current_xml_item, 'payslip/employee/number') 并运行查询，它完成了 OK，但是 @NINO 值没有插入到记录中，所以它似乎没有得到要么。
