ORACLE 存储过程 in 参数问题

直接  SUBSTR(r.rlpfid,1,2) IN (i_water_property)  时，当参数为一个数字时不存在问题，如01 ，若参数为01，02 则查不出结果，这时候用动态sql执行即可

execute immediate '   insert into temp_am(total_ysl,rlmiid)select ar.total_ysl,ar.rlmiid from   (select sum(r.rlsl) total_ysl,rlmiid from am_reclist r WHERE      r.rlrmonth >= :1      and r.rlrmonth <= :2      and r.rlstatus= :3      and SUBSTR(r.rlpfid,1,2) IN ('||i_water_property||')       group by rlmiid) ar   where   ar.total_ysl >=:4' using i_startmonth,i_endmonth,'N',v_total_ysl;
