我有这个代码。 :P99_CAR,:P99_PARTS是列表你可以选择一个ID(通过查找表),:P99_AMOUNT是我表单中的一个简单输入。因此,您选择这3个部分并想要检查以下代码。因此,如果PART_ID为5,且CAR_ID为3且我从列表中选择相同的数字,则ERROR即将到来,我不知道原因。

DECLARE
        --Varchar(100) or Number
      l_car Varchar(100);
      l_part Varchar(100);
    BEGIN
      SELECT CAR_ID, PART_ID INTO l_car, l_part FROM CAR_PARTS WHERE CAR_ID = :P99_CAR AND PARTS_ID = :P99_PARTS;
          IF l_car IS NULL OR l_parts IS NULL THEN 
              INSERT INTO CAR_PARTS (CAR_ID, PARTS_ID, CUR_AMOUNT) VALUES (:P99_CAR, :P99_PARTS, :P99_AMOUNT);
      ELSE
          UPDATE CAR_PARTS 
              SET CAR_ID = :P99_CAR,
                  PARTS_ID = :P99_PARTS,
                  CUR_AMOUNT = CUR_AMOUNT + :P99_AMOUNT
                      WHERE CAR_ID = :P99_CAR AND PARTS_ID = :P99_PARTS;
         END IF;
     END;

但是我在处理时收到ORA-01403错误,并在提交时

  

Ajax调用返回服务器错误ORA-01403:未找到Execute数据   PL / SQL代码。

我知道我需要插入一个带有ERROR的Exception,但为什么它会出现呢?

您的SELECT语句未返回任何行。由于这适用于不同的环境,因此绑定变量不是您认为的那样。您应该在此过程中添加对apex_debug.message的调用,然后检查调试日志中的值。

但是,我会用一个合并语句替换整个过程:

MERGE INTO car_parts cp
USING ( SELECT :P99_CAR_ID AS car_id, :P99_PARTS ID AS parts_id, 
               :P99_CUR_AMOUNT AS cur_amount ) src
   ON ( cp.car_id = src.car_id AND cp.parts_id = src.parts_id )
 WHEN NOT MATCHED THEN INSERT ( car_id, parts_id, cur_amount )
      VALUES ( src.car_id, src.parts_id, src.cur_amount )
 WHEN MATCED THEN UPDATE SET cur_amount = src.cur_amount

答案 1 :(得分:0)

以下查询似乎不会返回任何行:

SELECT CAR_ID, PART_ID INTO l_car, l_part FROM CAR_PARTS WHERE CAR_ID = :P99_CAR AND PARTS_ID = :P99_PARTS;

尝试将其包装在BEGIN END块中并处理异常:

BEGIN
  SELECT CAR_ID, PART_ID 
  INTO l_car, l_part 
  FROM CAR_PARTS 
  WHERE CAR_ID = :P99_CAR AND PARTS_ID = :P99_PARTS;
EXCEPTION WHEN NO_DATA_FOUND THEN
-- Handle error here
END;
