我在以下函数中遇到问题，在参数AD_Org_ID中，我想按如下所示作为字符串传递：

  select adempiere.qtyondateorg2 (2045480, '31/12/2018',' 2000002, 2000003');

但是我遇到以下错误：

错误：运算符不存在：数值=字符变化第10行：AND l.AD_Org_ID IN（org_id）

提示：没有运算符匹配给定的名称和参数类型。您可能需要添加显式类型转换。

对以正确方式形成功能的任何帮助吗？谢谢

您不能以这种方式使用IN运算符：

create or replace function wrong_func(org_id varchar)
returns boolean language plpgsql as $$
declare
    ad_org_id numeric = 1;
begin
    -- this raises an error as ad_org_id is numeric and org_id is varchar
    return ad_org_id in (org_id);
end $$;

select wrong_func('1,2,3');

ERROR:  operator does not exist: numeric = character varying
LINE 1: SELECT ad_org_id in (org_id)
                         ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

使用数字数组作为参数，如下所示：

create or replace function correct_func(org_id numeric[])
returns boolean language plpgsql as $$
declare
    ad_org_id numeric = 1;
begin
    return ad_org_id = any(org_id);
end $$;

select correct_func('{1,2,3}')

 correct_func 
--------------
 t
(1 row)
