【中文标题】如何使用以下代码获取 1 行中的数据【英文标题】：How to get data in 1 row using below code 【发布时间】：2017-04-24 11:15:15 【问题描述】：我想通过保持相应的 patient_id 来获取 1 行中的数据 iam 获取 1 行中的数据，但如果我通过提供函数 _patient_id 的输入参数执行 iam 数据将插入到 ams.ams_trans_integration_events 表中的 4 行中
elsif(_integration_type=34) 然后/患者注册/

【问题讨论】：
你想得到四行中的哪一行？.. 实际上我像这样进入 4 行 如果你得到 4 个相同的行，在SELECT 之后添加 DISTINCT
不，我的所有 4 行数据都不同，但我只想要最后一行数据
那么在哪里定义对应的子句？..
【参考方案1】：
改变
where p.patient_id= _patient_id)
到：
where p.patient_id= _patient_id and (select json_agg(patMailingAddressDetails)
from (
select cp.pat_cnt_address AS "address",
cp.pat_cnt_area AS "area",
cp.pat_cnt_pincode as "pinCode",
cp.pat_cnt_city as "city",
cp.pat_cnt_state as "state"
from xch.xch_transmasmap_patient_contact pc
left join xch.xch_transmas_patient_contact cp on cp.pat_cnt_id = pc.pat_contact_cnt_id
where pc.pat_contact_pat_id = _patient_id and pc.pat_contact_cnt_type_id = 4 and pc.pat_contact_isactive = true
)patMailingAddressDetails)->>'area' = 'ITPL')
