oracle用分隔符分割字段,并转为多行

作用:当判断是否满足条件,而条件字段又是用","分割的时候。

如果数据库中一个字段插入数据,并且以","分割。有点像行转列

select ur2.c_orgunitid

　　inner join (select level l from dual connect by level <= 100) b
　　on b.l <= length(p2.c_ranges) - length(replace(p2.c_ranges, ',')) + 1
　　inner join TB_ORG_UNITRELATION ur1 on ur1.c_orgunitid=regexp_substr(p2.c_ranges, '[^,]+', 1, l) and ur1.c_status=1
