存储过程中很复杂的字符串截取,弄了几天,我头大了
有如下字符串:(下列字符间相连,没有空格,为了方便观看,手工弄的空格)

离线记录^songlijun|8888888888|3500320083208#3500600520890#3500741122924#3500790143280#3501010510869#3500741129750

解释:
上面是多个文件中的数据拼接起来的。
以“%”相隔的是不同文件中的数据,上面只有3个文件,故只有2个“%”,若有n个文件,那么会有(n-1)个“%”。
以“|”相隔的依次为物流员(如“离线记录^songlijun”,物流员为songlijun),站点编号,包编号集合(如“3500320083208#3500600520890#3500741122924#3500790143280#3501010510869#3500741129750”)
以“^”相隔的“离线记录”为固定内容,“^”后为物流员(songlijun)
以“#”相隔的为包编号(如“3500320083208#3500600520890#3500741122924#3500790143280#3501010510869#3500741129750”中共有6个包编号,形如“3500320083208”)

目的:
得到物流员,站点编号,包编号(如“3500320083208”),插入到表中。

遇到问题:
做了几天,if-else太多了,弄得几个就晕了。

希望有好心人帮忙!感激不尽啊!第一次发帖,不知道给多少分。分不够的话,还可以再加啊! 要联系我的话,可以加我QQ:872082002
