Oracle 存储过程问题 - IN 和 OUT 变量是无效标识符 [关闭]

Question

我正在尝试在 Oracle 中创建存储过程，当我运行命令 SQL> start g:\oracle\totalsales.sql 它显示如下错误

ERROR at line 6:
ORA-06550: line 6, column 47:
PL/SQL: ORA-00904: "CID": invalid identifier
ORA-06550: line 6, column 4:
PL/SQL: SQL Statement ignored
ORA-06550: line 20, column 3:
PLS-00201: identifier 'TOT' must be declared
ORA-06550: line 20, column 3:
PL/SQL: Statement ignored

这是我的存储过程代码。请看一下并建议我缺少的点。

CREATE OF REPLACE PROCEDURE TotalSales (CID IN NUMBER, TOT OUT NUMBER)
IS
    DECLARE
        P Sales.Price%TYPE;
        T NUMBER(10,2) := 0;

        CURSOR CUR_SALES IS
            SELECT Price FROM Sales WHERE EmployeeID = CID;

    BEGIN
        OPEN CUR_SALES;
        LOOP
            FETCH CUR_SALES INTO P;
            IF CUR_SALES%ROWCOUNT = 0 THEN
                RAISE_APPLICATION_ERROR(-20020, 'No data found.');
            END IF;
            EXIT WHEN CUR_SALES%NOTFOUND;
            T := T + P;
        END LOOP;
        CLOSE CUR_SALES;

        TOT := T;

    EXCEPTION
        WHEN OTHERS THEN
        RAISE_APPLICATION_ERROR(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM);

END TotalSales;

改变

CREATE OF REPLACE

到

CREATE OR REPLACE

:)

并删除 DECLARE。 IS 隐含地标记了 DECLARE 块的开始。如果你想保留它，你需要用一个额外的 END 来关闭它 - 而且它还需要跟随开始。
