Question

我是SQL / PLSQL的新手，但我非常热衷于加快速度和学习（目前看似错误），所以请保持温和。

我已经交给另一位同事PLSQL代码进行测试。我将在以下几个方面解开。

我正在运行以下代码段示例：

    SELECT  cust_code || '_' || substr(p_year_code, 1, 2),      --using this brings an error
-- SELECT  cust_code --using this works fine         
            cust_title,                
            cust_dept_code,
            decode( cust_duration, ':', '0', '', '0',                                       
                    extract(hour from (to_timestamp(cust_duration,'hh24:MI'))) * 60 + 
                    extract(minute from (to_timestamp(cust_duration,'hh24:MI')))
                  ) cust_duration,
            cust_date,
            (CASE                                                                                   
               WHEN cust_date IS NOT NULL THEN                                               
                 to_date(to_char(cust_date,'DD-MM-YYYY') || ' ' || cust_time, 'DD-MM-YYYY HH24:MI')
               ELSE NULL
             END) cust_time,   
            cust_exp_code time_period,
            fw_person_get_desc('PERSON', cust_asmm_code ,null) cust_asmm_desc                        
    FROM    CUST,
            DETAIL
    WHERE   cust_examiner_id = detail_id(+)
    AND     detail_change_ind IS NULL               
    -- AND     cust_start_code <= p_year_code
    -- AND     cust_end_code >= p_year_code
    AND     cust_exp_code IN ('4', '5')
    AND     cust_asmm_code IN ('01', '02', '03', '06', '10')
    AND EXISTS (    SELECT 1 
                    FROM ACTIVITY
                    WHERE activity_asmt_code = cust_code
                    -- AND   activity_code = p_year_code
               );

然而，当我运行代码时，我收到错误ORA-00904：“p_year_code”无效标识符（如果有帮助则使用TOAD）我可以访问引用p_year_code的表和包（据我所见）我可以使用注释掉的详细行

来运行它

更新了包裹详细信息：

PROCEDURE pw_process_activity_details (

    p_year_code        IN   cust.cust_start_code%TYPE);

非常感谢有关测试SQL / PLSQL的任何进一步知识/建议。

干杯！杰克

选择查询返回错误：ORA-00904：无效的标识符
