Oracle行转列-列转行各种方式wm_concat函数、LISTAGG函数、PIVOT函数、UNPIVOT函数、非数字，以及自动动态获取要转换的列字段名（超详细）

1、上来先看下数据以及实现结果：

行转列（decode方式）：

WITH CO_ORDER AS(    SELECT 'DOM1' CUSTOMER, 'ZHA01' FACILITY , 4000 TEU FROM DUAL UNION ALL    SELECT 'DOM1' CUSTOMER, 'ZHA01' FACILITY , 5000 TEU FROM DUAL UNION ALL    SELECT 'DOM1' CUSTOMER, 'ZHA02' FACILITY , 9000 TEU FROM DUAL UNION ALL   SELECT 'DOM1' CUSTOMER, 'ZHA03' FACILITY , 9000 TEU FROM DUAL UNION ALL  SELECT 'DOM1' CUSTOMER, 'ZHA04' FACILITY , 4000 TEU FROM DUAL UNION ALL  SELECT 'DOM2' CUSTOMER, 'ZHA01' FACILITY , 6500 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA02' FACILITY , 6000 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA03' FACILITY , 5000 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA04' FACILITY , 3000 TEU FROM DUAL
)
SELECT T.CUSTOMER, SUM(DECODE(T.FACILITY, 'ZHA01', T.TEU)) AS ZHA01,SUM(DECODE(T.FACILITY, 'ZHA02', T.TEU)) AS ZHA02,SUM(DECODE(T.FACILITY, 'ZHA03', T.TEU)) AS ZHA03,SUM(DECODE(T.FACILITY, 'ZHA04', T.TEU)) AS ZHA04
FROM CO_ORDER T
GROUP BY T.CUSTOMER;

行转列（case when方式）：

WITH CO_ORDER AS(      SELECT 'DOM1' CUSTOMER, 'ZHA01' FACILITY , 4000 TEU FROM DUAL UNION ALL      SELECT 'DOM1' CUSTOMER, 'ZHA01' FACILITY , 5000 TEU FROM DUAL UNION ALL      SELECT 'DOM1' CUSTOMER, 'ZHA02' FACILITY , 9000 TEU FROM DUAL UNION ALL     SELECT 'DOM1' CUSTOMER, 'ZHA03' FACILITY , 9000 TEU FROM DUAL UNION ALL    SELECT 'DOM1' CUSTOMER, 'ZHA04' FACILITY , 4000 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA01' FACILITY , 6500 TEU FROM DUAL UNION ALL      SELECT 'DOM2' CUSTOMER, 'ZHA02' FACILITY , 6000 TEU FROM DUAL UNION ALL      SELECT 'DOM2' CUSTOMER, 'ZHA03' FACILITY , 5000 TEU FROM DUAL UNION ALL      SELECT 'DOM2' CUSTOMER, 'ZHA04' FACILITY , 3000 TEU FROM DUAL
)
SELECT CUSTOMER,SUM (CASE WHEN FACILITY = 'ZHA01' THEN TEU ELSE 0 END) AS ZHA01, SUM (CASE WHEN FACILITY = 'ZHA02' THEN TEU ELSE 0 END) AS ZHA02,SUM (CASE WHEN FACILITY = 'ZHA03' THEN TEU ELSE 0 END) AS ZHA03,SUM (CASE WHEN FACILITY = 'ZHA04' THEN TEU ELSE 0 END) AS ZHA04
FROM CO_ORDER GROUP BY CUSTOMER ORDER BY CUSTOMER;

行转列（PIVOT函数方式：）

WITH CO_ORDER AS(    SELECT 'DOM1' CUSTOMER, 'ZHA01' FACILITY , 4000 TEU FROM DUAL UNION ALL    SELECT 'DOM1' CUSTOMER, 'ZHA01' FACILITY , 5000 TEU FROM DUAL UNION ALL    SELECT 'DOM1' CUSTOMER, 'ZHA02' FACILITY , 9000 TEU FROM DUAL UNION ALL   SELECT 'DOM1' CUSTOMER, 'ZHA03' FACILITY , 9000 TEU FROM DUAL UNION ALL  SELECT 'DOM1' CUSTOMER, 'ZHA04' FACILITY , 4000 TEU FROM DUAL UNION ALL  SELECT 'DOM2' CUSTOMER, 'ZHA01' FACILITY , 6500 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA02' FACILITY , 6000 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA03' FACILITY , 5000 TEU FROM DUAL UNION ALL    SELECT 'DOM2' CUSTOMER, 'ZHA04' FACILITY , 3000 TEU FROM DUAL
)
SELECT * FROM (SELECT T.CUSTOMER, T.FACILITY, SUM(TEU) EU FROM CO_ORDER T GROUP BY T.CUSTOMER, T.FACILITY) T
PIVOT(SUM(T.EU) FOR FACILITY IN ('ZHA01', 'ZHA02', 'ZHA03', 'ZHA04'));

行转列（WM_CONCAT函数方式：）

WITH CO_ORDER AS(    SELECT 'DOM1' CUSTOMER, 'ZHA01&
