[英]SQL- SSRS Report
I am building a SSRS report and the data looks like as shown in the attached image.我正在构建一个 SSRS 报告,数据如下图所示。
I need to show the card number separately like primary and secondary based on the flag into new columns along with effective dates.我需要根据标志将卡号分别显示为主要和次要卡号以及生效日期。 If a customer has more than one card, i want to show the latest card information.
如果客户有不止一张卡,我想显示最新的卡信息。
How can i modify my sql script to get the desired output.如何修改我的 sql 脚本以获得所需的 output。
You can use conditional aggregation.您可以使用条件聚合。 I think this is the logic you want:
我认为这是您想要的逻辑:
select cif_id, staff_id, package, segment,
max(case when seqnum = 1 and primary_card_flag = 'Y' then card_number end),
max(case when seqnum = 1 and primary_card_flag = 'N' then card_number end),
max(case when seqnum = 1 and primary_card_flag = 'Y' then valid_from_date end),
max(case when seqnum = 1 and primary_card_flag = 'N' then valid_from_date end)
from (select t.*,
row_number() over (partition by cif_id, staff_id, package, segment, primary_card_flag
order by valid_from_date desc
) as seqnum
from t
) t
group by cif_id, staff_id, package, segment order;
