Question

我使用python

从PostgreSQL获取数据

    select submitter, issue, 
       (select max(q1) 
           from survey 
          where submitter = parent.submitter 
            and issue = parent.issue) as q1,
       (select max(q2) 
           from survey 
          where submitter = parent.submitter 
            and issue = parent.issue) as q2,
       (select max(q3) 
           from survey 
          where submitter = parent.submitter 
            and issue = parent.issue) as q3,
       (select max(q4) 
           from survey 
          where submitter = parent.submitter 
            and issue = parent.issue) as q4,
       (select max(q5) 
           from survey 
          where submitter = parent.submitter 
            and issue = parent.issue) as q5
from survery as parent
group by submitter, issue;

然后我尝试将此数据格式化为JSON格式：使用以下命令：

alter table survery add id bigint auto_increment;

但我在一个单独的行中得到了ID，姓名，地址......的每个字样：

例如：name = abc 执行脚本时我得到：

一

B'/ P>

C

Answer 1

您的结果（rows）是一个字符串（这是json.dumps()返回的内容）。这就是为什么当你通过行迭代时，你正在迭代并打印每个字符。

只需改为print rows

Answer 2

json.dumps()返回一个字符串，因此迭代返回每个字符。

要获取信息流，请使用json.dump()

将数据格式化为JSON
