方案一: sum case when
select brand,
max(case when area_name='东北' then total_price_actual else 0 end) db_price,
max(case when area_name='华北' then total_price_actual else 0 end) hb_price,
max(case when area_name='华东' then total_price_actual else 0 end) hd_price,
max(case when area_name='华南' then total_price_actual else 0 end) hn_price,
max(case when area_name='西南' then total_price_actual else 0 end) xn_price,
max(case when area_name='西北' then total_price_actual else 0 end) xb_price,
max(case when area_name='东北' then qty else 0 end) db_qty,
max(case when area_name='华北' then qty else 0 end) hb_qty,
max(case when area_name='华东' then qty else 0 end) hd_qty,
max(case when area_name='华南' then qty else 0 end) hn_qty,
max(case when area_name='西南' then qty else 0 end) xn_qty,
max(case when area_name='西北' then qty else 0 end) xb_qty
from (
select brand, area_name, sum(total_price_actual) total_price_actual, sum(qty) qty
from hive_temp_vipvop.vop_xstore_retail
group by brand, area_name
) tmp
group by brand
方案二:
select brand,
kv1['华北'] hb_price, kv2['华北'] hb_qty,
kv1['华东'] hd_price, kv2['华东'] hd_qty,
kv1['东北'] db_price, kv2['东北'] db_qty,
kv1['华南'] hn_price, kv2['华南'] hn_qty,
kv1['西南'] sn_price, kv2['西南'] xn_qty,
kv1['西北'] xb_price, kv2['西北'] xb_qty
from (
select brand, str_to_map(concat_ws(',', collect_set(concat(area_name, '-', total_price_actual))),',','-') kv1,
str_to_map(concat_ws(',', collect_set(concat(area_name, '-', qty))),',','-') kv2
from (
select brand, area_name, sum(total_price_actual) total_price_actual, sum(qty) qty
from hive_temp_vipvop.vop_xstore_retail
group by brand, area_name
) tmp
group by brand
) t
CONCAT 函数
CONCAT() 函数可将两个或多个字符串连接成一个字符串,
语法如下: CONCAT ( input_string1, input_string2 [, input_stringN ] );
collect_set 函数
collect_set(col)函数只接受基本数据类型,它的主要作用是将某字段的值进行去重汇总,产生array类型字段。
concat_ws 函数
concat_ws()函数用于在拼接的时候指定分隔符,CONCAT_WS(separator,str1,str2,…)
str_to_map 函数
str_to_map(text[, delimiter1, delimiter2]). 使用两个分隔符将文本拆分为键值对。Delimiter1将文本分成K-V对,Delimiter2分割每个K-V对。
