具有 XML 字符串的 MySql 数据库表。如何将该数据导入另一个mysql表

Question

我有一个名为 table's 的人。此表的列“outsourcedData”包含以下 xml 作为字符串：

<person>
    <educations total="2">
        <education>
            <school-name>Delhi University</school-name>
            <degree>Master of Science (MSc)</degree>
            <field-of-study>Banking and Financial Support Services</field-of-study>
            <start-date>
                <year>2009</year>
            </start-date>
            <end-date>
                <year>2013</year>
            </end-date>
        </education>
        <education>
            <school-name>American University</school-name>
            <degree>Bachelor of Arts (BA)</degree>
            <field-of-study>Business Administration and Management, General</field-of-study>
        </education>
    </educations>
</person>

此表中有许多类似的行可用。有什么办法可以加载这些数据解析并插入到教育表中。

There are lots of row I am having in my database. But now I want to import this data into new table Education which I newly created in database corresponding fields with xml.(SchoolName,degree......).    

在 Mysql 数据库中，迁移此数据库的最佳方法是什么。
我被困在这个地方。请帮忙。帮助

create table person (id int,outersource varchar(1024));
insert into person values(1,'<?xml version="1.0" encoding="UTF-8" standalone="yes"?><person><educations total="2"><education><school-name>Delhi University</school-name><degree>Master of Science (MSc)</degree><field-of-study>Banking and Financial Support Services</field-of-study><start-date><year>2009</year></start-date><end-date><year>2013</year></end-date></education><education><school-name>American University</school-name><degree>Bachelor of Arts (BA)</degree><field-of-study>Business Administration and Management, General</field-of-study></education></educations></person>');
create table education( schoolName varchar(255), degree varchar(255),start_year datetime, end_year datetime);

任何我们可以做到这一点的存储过程？

原来的问题是这样的。我有三张桌子。存在 xml 字符串数据的第一个表和用于此 xml 字符串解析的两个新表。父表包含学校名称 + 用户 ID 唯一组合。在解析 xml 期间，如果任何节点包含与保存到子表中的数据相同的学校名称 + 用户 ID。 此子表具有此父表的引用。使用下面的存储过程。

CREATE DEFINER=`teneqs`@`localhost` PROCEDURE `xxx`()

    declare v_row_index int unsigned default 0;
    declare v_row_count int unsigned;
    declare v_xpath_row varchar(255);
    declare userId int;
    declare userEduInfoId int;
    declare p_xml   text;
    declare p_xpath_row varchar(255) default '//educations[1]/education';
 declare done int;


DECLARE outsourcedUserDataCursor CURSOR FOR  select user_id, data from source_table where sourceType='LINKED_IN' order by user_id;
OPEN outsourcedUserDataCursor;
 outsourcedUserDataCursor_loop:
        LOOP FETCH outsourcedUserDataCursor INTO userId,p_xml;
       Set v_row_index := 0;
       -- SET done := 0;
       select userId,p_xml;
    -- calculate the number of row elements.
     set v_row_count := extractValue(

            ,   ')'
            )
        );

        IF v_row_count > 0 THEN
            -- loop through all the row elements
            while v_row_index < v_row_count do       
                set v_row_index := v_row_index + 1;
                set v_xpath_row := concat(

我厌倦了这个存储过程，但有一个问题。只有一条记录插入到父表中，其他记录插入到另一个子表中。 请纠正我做错的地方。
