概念：一个instance分为runnable(schedule生成，用于在recurring时间点创建其他Instance), 非runnable（runnable instance生成的结果）。
SI_INSTANCE = SI_INSTANCE_OBJECT + SI_RUNNABLE_OBJECT
验证通过
select * from ci_infoobjects where SI_RUNNABLE_OBJECT=1 2
select * from ci_infoobjects where SI_INSTANCE_OBJECT=1 140
select * from ci_infoobjects where SI_INSTANCE=1 142
