ORA-00922: 创建 PL/SQL 过程时选项丢失或无效

Question

在创建 PL/SQL 过程时出现 ORA-00922 错误：缺少或无效选项，这里是过程。

CREATE OR REPLACE consession_calculate(item_ID IN NUMBER, CON_PRICE OUT NUMBER)
IS 
PRICE NUMBER;
BEGIN
SELECT ITEM_PRICE INTO PRICE FROM ITEM WHERE ITEM_CODE=item_ID;
IF(PRICE<10) THEN
CON_PRICE:=PRICE;
ELSEIF(PRICE>=10 AND PRICE<=100) THEN
CON_PRICE:=(PRICE*10)*100;
ELSE 
CON_PRICE:=(PRICE*20)*100;
END IF;
END;

Answer 1

你有一些问题：

• 您缺少 PROCEDURE 关键字
• ELSEIF 应该是 ELSE IF
• 你不见了，END IF。

编辑后的代码：

CREATE OR REPLACE PROCEDURE consession_calculate(item_ID IN NUMBER, CON_PRICE OUT NUMBER) IS
    PRICE                                   NUMBER;
BEGIN
    SELECT ITEM_PRICE
      INTO PRICE
      FROM ITEM
     WHERE ITEM_CODE = item_ID;

    IF (PRICE < 10)
    THEN
        CON_PRICE    := PRICE;
    ELSE
        IF (    PRICE >= 10
            AND PRICE <= 100)
        THEN
            CON_PRICE    := (PRICE * 10) * 100;
        ELSE
            CON_PRICE    := (PRICE * 20) * 100;
        END IF;
    END IF;
END;
/

或者，根据 a_horse_with_no_name 注意到的情况，您只能添加 PROCEDURE 并将 ELSEIF 编辑为 ELSIF：

CREATE OR REPLACE PROCEDURE consession_calculate(item_ID IN NUMBER, CON_PRICE OUT NUMBER) IS
    PRICE                                   NUMBER;
BEGIN
    SELECT ITEM_PRICE
      INTO PRICE
      FROM ITEM
     WHERE ITEM_CODE = item_ID;

    IF (PRICE < 10)
    THEN
        CON_PRICE    := PRICE;
    ELSIF (    PRICE >= 10
           AND PRICE <= 100)
    THEN
        CON_PRICE    := (PRICE * 10) * 100;
    ELSE
        CON_PRICE    := (PRICE * 20) * 100;
    END IF;
END;
