我有一个看起来像这样的XML文件:
<?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语句将其导入MySQL:
use databasename; LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename;
表my_tablename具有以下字段:
id (auto increment id) personal_number(varchar) firstname(varchar) lastname(varchar) email(varchar) start_time(varchar) end_time(varchar) employee_category(varchar)
我收到错误消息:错误代码:1136列数与第1行的值数不匹配
我正在使用MySQL 5.1.56
我认为发生此错误是因为数据库表具有字段ID,该字段ID在XML文件中不存在。如何使用内置函数的MySQL查询来导入此XML文件,以使其在导入过程中跳过id列并依赖id列的自动递增功能?是否有一些更聪明的方法来处理MySQL中的XML文件导入?也许有更好的语句可以指定列映射?
谢谢!
您可以指定如下字段:
LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename(personal_number, firstname, ...);
