父子項(xiàng)排序

with tb as

(

--省級(jí)

select 'e' subcode,'e'parentcode,'湖北' AREA,'SO' TYPE,10 QTY FROM DUAL UNION ALL

select 'e' subcode,'e'parentcode,'湖北' AREA,'INV' TYPE,10 QTY FROM DUAL UNION ALL----

select 'e' subcode,'e'parentcode,'湖北' AREA,'BOUND' TYPE,10 QTY FROM DUAL UNION ALL

--地市

select 'c' subcode,'e'parentcode,'武漢' AREA,'SO' TYPE,10 QTY FROM DUAL UNION ALL

select 'c' subcode,'e'parentcode,'武漢' AREA,'INV' TYPE,20 QTY FROM DUAL UNION ALL----

select 'c' subcode,'e'parentcode,'武漢' AREA,'BOUND' TYPE,10 QTY FROM DUAL UNION ALL

--地市

select 'd' subcode,'e'parentcode,'漢口' AREA,'SO' TYPE,10 QTY FROM DUAL UNION ALL

select 'd' subcode,'e'parentcode,'漢口' AREA,'INV' TYPE,30 QTY FROM DUAL UNION ALL----

select 'd' subcode,'e'parentcode,'漢口' AREA,'BOUND' TYPE,20 QTY FROM DUAL UNION ALL

--省份

select 'a' subcode,'a'parentcode,'廣東' AREA,'SO' TYPE,10 QTY FROM DUAL UNION ALL

select 'a' subcode,'a'parentcode,'廣東' AREA,'INV' TYPE,60 QTY FROM DUAL UNION ALL----

select 'a' subcode,'a'parentcode,'廣東' AREA,'BOUND' TYPE,10 QTY FROM DUAL UNION ALL

--地市

select 'h' subcode,'a'parentcode,'廣州' AREA,'SO' TYPE,10 QTY FROM DUAL UNION ALL

select 'h' subcode,'a'parentcode,'廣州' AREA,'INV' TYPE,20 QTY FROM DUAL UNION ALL----

select 'h' subcode,'a'parentcode,'廣州' AREA,'BOUND' TYPE,10 QTY FROM DUAL UNION ALL

--地市

select 'g' subcode,'a'parentcode,'深圳' AREA,'SO' TYPE,10 QTY FROM DUAL UNION ALL

select 'g' subcode,'a'parentcode,'深圳' AREA,'INV' TYPE,30 QTY FROM DUAL UNION ALL----

select 'g' subcode,'a'parentcode,'深圳' AREA,'BOUND' TYPE,20 QTY FROM DUAL

)

select * from tb;

要求

--按 省級(jí) TYPE類型的INV庫(kù)存數(shù)量 從大到小排序(廣東INV=60 大于湖北INV=10)，再按 地市的TYPE類型的INV庫(kù)存數(shù)量 從大到小排序(深圳INV 30大于廣州INV 20)；

但 地市級(jí)要緊接在省份后面

效果如下；
