Question

我修改了对任务＃2的要求。我想知道是否有人可以帮助我。我试图从ITEM列获取记录不在任务＃1和任务＃3中的总和。

非常感谢。

我创建了一个简单的表和一些原始数据。我试图完成以下任务：

a.Sum记录中包含'FIRA'作为FIRA。
b.Sum记录中包含'FMUA'作为FMUA。
c.Sum记录包含'SOTA'作为SOTA。
d.Sum记录中包含'PERA'作为PERA。
e.Sum记录中包含'SGDA'作为SGDA。
f.Sum记录包含'TGDA'作为TGDA。
h.Sum记录中包含'CRMA'作为CRMA。
汇总非任务＃1和任务＃3 AS MULTIPLE_CLASSIFICATION的记录。
将上述＃1和＃2以外的其余记录汇总为NONE_CLASSIFICATION。

我能够完成任务＃1和＃3但无法完成任务＃2 下面是我在SQL Server和Oracle中测试的查询。

CREATE TABLE TEMP
(
  CLASSIFICATION VARCHAR (100),
  ITEM           INTEGER
)

insert into temp values ('CRMA', 66);
insert into temp values ('FIRA', 1288);
insert into temp values ('FIRA/ATEPT/DR', 3);
insert into temp values ('DR/SERA/ATEPT/FIRA', 4);
insert into temp values ('PERA', 1311);
insert into temp values ('STATE/SERA/PERA/ERS', 1);
insert into temp values ('null', 136);
insert into temp values ('PERA/DR/ATEPT', 4);
insert into temp values ('SOTA', 1);
insert into temp values ('FERA/SOTA', 1);
insert into temp values ('SOTA/SATO/DT', 1);
insert into temp values ('FMUA', 5);
insert into temp values ('SERA', 8);
insert into temp values ('SGDA', 3);
insert into temp values ('TGDA', 1);
insert into temp values ('TGDA/ATPET', 1);
insert into temp values ('ATPET', 15);
insert into temp values ('CRMA/PERA', 2);
insert into temp values ('SERA/FIRA/ATEPT/SGDA/SGD', 5);
insert into temp values ('FIRE/FIRA/SERA/DR/SOTA', 4)

Answer 1

您的任务2包含“FIRA”，其值为1288.由于1288大于您期望的总和，因此您的总和查询应修改为仅包含您正在查找的值的类型对于。请参阅您的插入内容：

insert into temp values ('FIRA', 1288);

和您的查询：

--for task #2
SUM (CASE WHEN ( CLASSIFICATION LIKE '%FIRA%'
OR CLASSIFICATION LIKE '%FMUA%'
OR CLASSIFICATION LIKE '%SOTA%'
OR CLASSIFICATION LIKE '%PERA%'
OR CLASSIFICATION LIKE '%SGDA%'
OR CLASSIFICATION LIKE '%TGDA%'
OR CLASSIFICATION LIKE '%CRMA%') THEN ITEM END) AS MULIPLE_CLASSIFICATIONS,

在SQL Server或Oracle中使用case语句
