根据列值计算总计

Question

 AWBNO               STATUS
 123                DELIVERED
 125                DELIVERED
 124                   RTO
 126                   RTO
 127                   NDR
 128                   NDR
 131                DELIVERED
 132                DELIVERED
 133                   NDR
 134                DELIVERED

我想以这种方式输出： -

TOTAL       DELIVERED     RTO     NDR
10              5          2       3

Answer 1

您可以根据以下状态执行条件聚合：

select 
    count(*) total,
    count(case when status = 'DELIVERED' then 1 end) DELIVERED,
    count(case when status = 'RTO' then 1 end) RTO,
    count(case when status = 'NDR' then 1 end) NDR
