PostgresException：42703：关系“ y”的列“ x”不存在

Question

我正在尝试从.net核心运行存储过程，这给了我一个错误：

  

PostgresException：42703：关系“ AcceptanceActLines”的列“ AcceptanceActID”不存在

这是我正在尝试运行的查询：

create or replace function "ClosePeriod"(month integer, year integer) 
returns void
    language plpgsql
as
$$
DECLARE
BEGIN

INSERT INTO billing."AcceptanceActs"("AccountID", "Month",  "Year","Amount")
SELECT
    DISTINCT th."AccountID",
    "month",
    "year",
    th."TotalAmount"


FROM billing."TransactionHeaders" AS th
    WHERE th."AcceptanceActID" IS NULL;


UPDATE billing."TransactionHeaders" set "AcceptanceActID" = acc."ID" from 
billing."AcceptanceActs" acc
    where acc."Year"="year" AND acc."Month"="month" AND 
    acc."AccountID"=billing."TransactionHeaders"."AccountID"
    AND billing."TransactionHeaders"."AcceptanceActID" is null;


INSERT INTO billing."AcceptanceActLines"("PackageId","Amount","AcceptanceActID")
SELECT
    tl."PackageID",
    SUM(tl."Amount"),
    aa."ID"
FROM billing."TransactionHeaders" AS th
INNER JOIN billing."TransactionLines" AS tl ON th."Id" = tl."TransactionHeaderID"
INNER JOIN billing."AcceptanceActs" as aa ON th."AcceptanceActID" = 
aa."ID"
    WHERE aa."Month"=="month" AND aa."Year"=="year"
    GROUP BY tl."PackageID", aa."ID";

END;
$$;

 alter function "ClosePeriod"(integer, integer) owner to postgres;
