如何使用XML_LOAD()将XML文件导入MySQL数据库表; 功能

Question

我有一个XML文件,如下所示:

    <?xml version="1.0" encoding="UTF-8"?>

<resultset statement="YOUR SQL STATEMENTS TO GENERATE THIS XML FILE" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <row>
    <field name="personal_number">539</field>
    <field name="firstname">Name</field>
    <field name="lastname">Surname</field>
    <field name="email">email.domain.com</field>
    <field name="start_time">2011-04-02 13:30:00</field>
    <field name="end_time">2011-04-02 18:15:00</field>
    <field name="employee_category">1,2,4,5,22,37,38,39,41,43,44</field>
  </row>
  <row>
    <field name="personal_number">539</field>
    <field name="firstname">Name</field>
    <field name="lastname">Surname</field>
    <field name="email">email.domain.com</field>
    <field name="start_time">2011-04-02 13:30:00</field>
    <field name="end_time">2011-04-02 18:15:00</field>
    <field name="employee_category">1,2,4,5,22,37,38,39,41,43,44</field>
  </row>
  <row>
    <field name="personal_number">539</field>
    <field name="firstname">Name</field>
    <field name="lastname">Surname</field>
    <field name="email">email.domain.com</field>
    <field name="start_time">2011-04-02 13:30:00</field>
    <field name="end_time">2011-04-02 18:15:00</field>
    <field name="employee_category">1,2,4,5,22,37,38,39,41,43,44</field>
  </row>

我试图使用SQL语句在MySQL中导入它:

use databasename;
LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename;

表my_tablename包含以下字段:

id (auto increment id)
personal_number(varchar)
firstname(varchar) 
lastname(varchar)
email(varchar) 
start_time(varchar)
end_time(varchar)
employee_category(varchar)

我收到错误:错误代码:1136列数与第1行的值计数不匹配

我正在使用MySQL 5.1.56

我假设发生此错误是因为数据库表具有字段ID,这在XML文件中不存在.如何使用内置函数的MySQL查询导入此XML文件,以便在导入期间跳过id列并依赖于id列的自动递增函数？是否有一些更聪明的方法来处理MySQL文件导入？也许有更好的声明允许指定列映射？

谢谢!

Answer 1

你可以指定这样的字段:

LOAD XML LOCAL INFILE '/pathtofile/file.xml' 
INTO TABLE my_tablename(personal_number, firstname, ...); 

Answer 2

由于ID是自动递增,您还可以指定ID = NULL,

LOAD XML LOCAL INFILE'/pathtofile/file.xml'INTO TABLE my_tablename SET ID = NULL;
