存储过程学习（004）--象写程序一样的写存储过程及调试

业务描述：从HR系统中同步人员信息（新入职，离职）

/*
同步HR系统新入职及离职员工数据
新入职：插入到对应部门的未分配部门里，事业部需区分文职，非文职 并插入信息到OA的员工表
处理过的用户标记为2

数据量不要超过1000条，否则有可能报错^_^.

数据源：tb_oa_employee（HR）
目标：OA_TAB_STAFF，OA_TAB_GWSTAFFS

碰到的问题：循环时发现，所有的记录状态都变为2了，也就是都被处理过了。可实际上有些记录的@postid is null,应该不会执行才对。找了一下原来是select赋值的问题，当为空时，select 赋值会保留上一次的数据。
