如果记录组中存在状态，则跳过sql

Question

如果批量中存在某种类型的记录，我试图从查询中跳过一组记录。

我有这样的记录

ORDER        STATUS
1234         X
1234         Y
1234         Z
1235         X
1235         Y
1236         X
1237         X
1237         Y
1238         A
1238         B

如您所见，订单经历了多个阶段（X，Y，Z，A，B）。我想选择没有达到某种状态的订单，即Z或B.所以从上表中我只应该选择订单号和状态，其中该订单的状态没有转到Z或B.

感谢任何帮助。 感谢。

Answer 1

使用select t.* from t where not exists (select 1 from t t2 where t2.order = t.order and t2.status in ('Z', 'B')); ：

select order
from t
group by order
having sum(case when status in ('Z', 'B') then 1 else 0 end) = 0;

如果您只想要没有这些状态的订单，可以使用聚合：

i = inp

i = Conv2D(filters = 64, kernel_size = 4)(i)
i = BatchNormalization()(i)
i = LeakyReLU()(i)
i = MaxPooling2D(2)(i)    
i = Conv2D(filters = 64, kernel_size = 4)(i)    
i = BatchNormalization()(i)
i = LeakyReLU()(i)
i = MaxPooling2D(2)(i)    
i = Conv2D(filters = 64, kernel_size = 4)(i)
i = BatchNormalization()(i)
i = LeakyReLU()(i)
i = MaxPooling2D(2)(i)
i = Conv2D(filters = 64, kernel_size = 4)(i)
i = BatchNormalization()(i)
i = LeakyReLU()(i)

i = GlobalMaxPooling2D()(i)

i = Dense(len(labels), activation = 'softmax')(i)

Answer 2

试试这个

SELECT * FROM table_name WHERE STATUS NOT LIKE('B') AND STATUS NOT LIKE('Z');

这将返回所有未达到状态 B 或 Z 的记录。
