Question

我在创建

的程序上遇到两个错误

错误是：

语句被忽略
ORA-00918：列模糊定义

这是我的代码，给出错误的行有对它们的评论：

CREATE OR REPLACE PROCEDURE get_route_times(route IN VARCHAR2, day IN VARCHAR2, 
refcursor OUT sys_refcursor)
AS
cursorSend  sys_refcursor;  
BEGIN

    OPEN cursorSend FOR

    CASE

      END AS "4"


     FROM BBT_ROUTESTOP RS
     INNER JOIN SATFREQ sat
     ON RS.ROUTE_NO = sat.ROUTE
     INNER JOIN SUNFREQ sun
     ON RS.ROUTE_NO = sun.ROUTE
     INNER JOIN WEEKFREQ week
      ON RS.ROUTE_NO = week.ROUTE
      WHERE lower(RS.ROUTE_NO)=lower(route)
      Order by RS.DIRECTION ASC;

      refcursor := cursorSend;
    END;

我已经看了好几个小时了，对不起，如果这没有意义，我希望你能提供帮助！

Answer 1

您有route作为存储过程的参数，它也是SATFREQ，SUNFREQ和WEEKFREQ表中的一列，查询无法解决在哪一行：WHERE lower(RS.ROUTE_NO)=lower(route)。

重命名参数：

CREATE OR REPLACE PROCEDURE get_route_times(
  in_route   IN  VARCHAR2,
  in_day     IN  VARCHAR2, 
  out_cursor OUT sys_refcursor)
AS
BEGIN
  OPEN out_cursor FOR
  SELECT RS.ROUTE_NO,
         RS.DIRECTION,
         RS.STOP_NAME,
         RS.JOURNEY_TIME,
         to_char(
           trunc(sysdate-1/24, 'HH') + RS.JOURNEY_TIME/1440,
           'HH24:MI'
         ) AS "1",
         to_char(
           trunc(sysdate-1/24, 'HH')
             + RS.JOURNEY_TIME/1440
             + 1 * CASE lower(in_day) WHEN 'sat' THEN Sat.FREQUENCY
                                      WHEN 'sat' THEN Sun.FREQUENCY
                                      ELSE Week.FREQUENCY END,
           'HH24:MI'
         ) AS "2",
         to_char(
           trunc(sysdate-1/24, 'HH')
             + RS.JOURNEY_TIME/1440
             + 2 * CASE lower(in_day) WHEN 'sat' THEN Sat.FREQUENCY
                                      WHEN 'sat' THEN Sun.FREQUENCY
                                      ELSE Week.FREQUENCY END,
