如何在postgresql中从数组\返回到\字符串的和

我需要从数组中只有整数值的数组_到字符串函数的求和结果

SELECT
    state_name,
    "ST_CODE" ,
    dist_name ,
    "DIST_CODE",
    subdist_name,
    "SUBDIST_CODE",
    array_to_string(array_agg(distinct jan_sale::numeric), ',') as super
FROM village_details_new , aw
WHERE
    "ST_CODE"::integer=3
    AND village_details_new.aw_code::integer = aw.aw_code::integer
group by
    "SUBDIST_CODE",
    state_name,
    "ST_CODE" ,
    dist_name ,
    "DIST_CODE",
    subdist_name
order by "SUBDIST_CODE"

我需要一笔钱

sum(array_to_string(array_agg(distinct jan_sale::numeric), ',') as super) 

但它不起作用，请帮忙

等待你的实际数据是什么？它是一个数组吗？你怎么知道jan_sale是什么？源数据是什么样子的？它是如何构造的？这个

aw

表是什么？它的数据是什么？这就是数组所在的位置吗？如何对逗号分隔的字符串列表进行“求和”？“不工作”不是有效的Postgres错误消息。yaa我需要逗号分隔的整数列表的总和如何做？？？在将它们放入逗号分隔的列表之前求和如何做，请指定我编写了整个sql。。。。

sum(distinct jan_sale)::numeric as super
