1 select id, 2 name, 3 sum(decode(tag_name, 'AAA', nvl(value, 0),'BBB' ,nvl(value, 0),0)) "imp_value", 4 sum(decode(tag_name, 'C01', nvl(value, 0),'D01', nvl(value, 0), 0)) "click_value" 5 6 from (SELECT a.id, a.name, d.tag_name, d.value 7 FROM A a 8 LEFT JOIN B b 9 ON a.id = b.id 10 left join d d 11 on b.imp_url = d.tag_name 12 union 13 SELECT a.id, a.name, d.tag_name, d.value 14 FROM A a 15 LEFT JOIN C c 16 ON a.id = c.id 17 left join d d 18 on c.click_url = d.tag_name) m 19 group by id, name
下面是根据id和name 将value合并成一列
1 select id, 2 name, 3 to_char(WMSYS.WM_CONCAT(tag_name)) tag_name, 4 to_char(WMSYS.WM_CONCAT(value)) value 5 from (SELECT a.id, a.name, d.tag_name, d.value 6 FROM A a 7 LEFT JOIN B b 8 ON a.id = b.id 9 left join d d 10 on b.imp_url = d.tag_name 11 union 12 SELECT a.id, a.name, d.tag_name, d.value 13 FROM A a 14 LEFT JOIN C c 15 ON a.id = c.id 16 left join d d 17 on c.click_url = d.tag_name) m 18 group by id, name
