创建存储过程编译错误

Question

我正在尝试在 oracle 中创建一个存储过程，但每次我尝试将其添加到数据库中时，我都会收到错误消息 Procedure created with compilation errors

我无法执行它（也会出错）。我想我的实际程序有问题，但我无法弄清楚。这是我正在尝试创建的程序：

CREATE PROCEDURE SPBILL @CLIENT_ID VARCHAR2(6)
AS 
BEGIN
    SELECT C.CLIENT_NAME, B.ROOM_ID, R.ROOM_COST, T.TREAT_NAME, T.TREAT_COST, (ROOM_COST*(B_END_DATE-B_START_DATE)+TREAT_COST) AS INVOICE
    FROM CLIENTS C, ROOMS R, TREATMENTS T, BOOKING B, PRESCRIPTION P
    WHERE C.CLIENT_ID=B.CLIENT_ID
    AND R.ROOM_ID=B.ROOM_ID
    AND B.CLIENT_ID=P.CLIENT_ID
    AND P.TREAT_ID=T.TREAT_ID
    AND C.CLIENT_ID=@CLIENT_ID
END;

Answer 1

这一定很傻，但我认为这是您声明变量@CLIENT_ID的方式

您是否尝试过像这样DELCARE @CLIENT_ID VARCHAR2(6) 声明变量？

看这个链接How to use local variables in stored procedures?

Answer 2

像下面这样试试

CREATE PROCEDURE SPBILL (CLIENT_ID VARCHAR2)
AS 
BEGIN
   SELECT C.CLIENT_NAME, B.ROOM_ID, R.ROOM_COST, T.TREAT_NAME, T.TREAT_COST, (ROOM_COST*(B_END_DATE-B_START_DATE)+TREAT_COST) AS INVOICE
   FROM CLIENTS C, ROOMS R, TREATMENTS T, BOOKING B, PRESCRIPTION P
   WHERE C.CLIENT_ID=B.CLIENT_ID
   AND R.ROOM_ID=B.ROOM_ID
   AND B.CLIENT_ID=P.CLIENT_ID
   AND P.TREAT_ID=T.TREAT_ID
   AND C.CLIENT_ID= CLIENT_ID 
END;
