数据库 oracle 列转行 PIVOT

• 各位大佬我现在就是这样 select出来有数据的
  

• 然后我PIVOT 的话就会报错
  
  *他这边PIVOT 的in里面的类型要和我查出来的dl_name数量对应嘛 他好多数量都不是固定的
  

• 我语法有问题吧 他这个的正确写法应该是什么呀

这是我的代码

 select * from(select 
                 XT_INSTANCE.行政区名称, 
                 UT_SP_CLASS_AREA_DTL.UNIT_NAME ,
                 ut_sp_dl_dict.dl_name,
                 ut_sp_class_area_dtl2.dl_value
                 from XT_INSTANCE,UT_SP_CLASS_AREA_DTL,UT_SP_BUILD_PROJ_LAND,UT_SP_CLASS_AREA_DTL2,ut_sp_dl_dict,sys_landtype_dict   
                 where 1=1
                 and   UT_SP_BUILD_PROJ_LAND.Iid=XT_INSTANCE.Iid
                 and   UT_SP_BUILD_PROJ_LAND.iid=UT_SP_CLASS_AREA_DTL.iid
                 and UT_SP_CLASS_AREA_DTL.Iid=UT_SP_CLASS_AREA_DTL2.Iid
                 and ut_sp_dl_dict.type=2
                 and ut_sp_dl_dict.dl_id=ut_sp_dl_dict.dl_id
                 and ut_sp_dl_dict.dl_id=sys_landtype_dict.pro_code
                 and sys_landtype_dict.pro_code=ut_sp_class_area_dtl2.dl_id) p;

                 PIVOT ( sum(p.dl_value)for
                 p.dl_name in ([空闲地],[坑塘水面],[河流水面],[空闲地],[坑塘水面],[河流水面]))t 

//问题一：分号不应该弄p后面 而应该在最后
//问题二： p.dl_name in的字段有重复相同字段
--如果还不行 可联系QQ434317590 一起探讨下
