Question

我无法更改ln_graph_debt.date_red

CREATE OR REPLACE PROCEDURE GetContactFormalNames
AS
   aki     DATE := TRUNC (SYSDATE - 3);
   aki_1   DATE := TRUNC (ln_graph_debt.date_red);
BEGIN
   IF (aki_1 = aki)
   THEN
      DECLARE account_name_1 AS INT*/

      INSERT INTO TEL_LOAN_GRAPH (loan_id,
                                  TOTAL_COUNTED,
                                  DATE_RED,
                                  OBLIGATE_NUMBER,
                                  ACCOUNT_CODE,
                                  ACCOUNT_NAME)
         SELECT d.loan_id,
                CAST (d.summ_red AS NUMBER) + CAST (p.summ_red AS NUMBER)
                   AS Total_Counted,
                d.date_red,
                d.obligate_number,
                l.account_code,
                l.account_name
           FROM ln_graph_debt d, ln_graph_perc p, ln_account l
          WHERE     d.loan_id = p.loan_id
                AND d.loan_id = l.loan_id
                AND p.date_red = d.date_red;
   END IF;
END GetContactFormalNames;

Answer 1

这是错误的：

aki_1   DATE := TRUNC (ln_graph_debt.date_red);

您不能以这种方式引用表；您将必须SELECT进入变量，或编写一个将返回值的函数。

select d.date_red
  into aki_1
  from ln_graph_debt d
  where ...

WHERE子句应包含一个条件，以便SELECT仅返回单个值；否则，您会得到TOO-MANY-ROWS（或者也许是NO-DATA-FOUND）。

还有一个明显的错误，DECLARE中多余的IF。您可能想发表评论？

在此上下文中不允许使用表，视图或序列引用“ LN_GRAPH_PERC.DATE_RED”
