为了让一个多值表中的数据，通过合理的处理来自动生成一个想要的简易表，并且是把原数据表中的数据合拢后按规定格式放在一行中。这样就可以在查询时，按行进行查询。整个存储过程使用了两个循环，而后考虑各个特定数据对应的行，通过行标来更新相应行数据。

//从这一个存储过程中可以看出数据处理的复杂性和原理的简易性。如果要处理一组很复杂的数据，首先应该从原理上去找突破点，找到原理性的东西后，按编程的思想把存储过程写下来，然后翻译成sql语句。再慢慢调试，最后得到想要的结果。调试时可以采用单数据调试，便于过程的运行，这样成功后，再全面调试，找到出错的位置，然后在这一位置处分析数据，找处特殊数据，来进行修改。以满足全部数据的处理。
