Sql oracle过程的多值性

我想在Oracle 11g中使用

p\u so\u code

添加多值，其中

so在（A，B，C）

中

---

我尝试了使用

replace（p_so_code，（'，），（'''，''）

，但没有成功。

在p_so_代码中打破逗号分隔的值，返回多行值，然后在

in

子句中使用它

PROCEDURE get_one_so (
     p_SO_CODE in String,
     RES OUT SYS_REFCURSOR
)
    AS
BEGIN
    OPEN RES FOR 

   SELECT
        so.so_code as SOCODE,
        cus.customer_code as CUSTOMERCODE,            
        cus.customer_name as CUSTOMERNAME,
        cus.email as EMAIL,            
        so.receiver_name as RECEIVERNAME,
        so.receiver_phone as RECEIVERPHONE,
        so.receiver_address as RECEIVERADDRESS,
        so.commment as COMMMENT,
        s.name as STAFFCREATE,     
                    to_char( so.CREATED_DATE,'dd/mm/yyyy') as CREATEDDATE,
        st.name as STAFFUPDATE,
        to_char(so.updated_date,'dd/mm/yyyy') as UPDATEDATE,
        sapp.name as STAFFAPPROVE,
       status,            
            so.reason_reject as REASONREJECT,
        so.payment as PAYMENY,
        to_char(so.send_date,'dd/mm/yyyy')   as SENDDATE,
        to_char(so.sended_date,'dd/mm/yyyy')   as SENDEDATE,
        so.staff_comment as STAFFCOMMENT
    FROM
        saleorders so join customer cus on so.customer_code = cus.customer_code
        left join saleorderDetail sod on so.so_code = sod.so_code
        left join staff s on so.staff_create = s.staff_code
        left join staff st on so.staff_update = st.staff_code
        left join staff sapp on so.STAFF_APPROVE = sapp.staff_code
    WHERE
        so.so_code IN (SELECT regexp_substr(p_so_code, '[^,]+', 1, LEVEL) 
                         FROM dual 
                      connect by regexp_substr(p_SO_CODE, '[^,]+', 1, level) is not null);

END;

说“这不管用”没有多大帮助；最好解释一下到底发生了什么以及为什么这不是你想要的。

p_so_code

是否必须是字符串，或者是否可以将参数的数据类型更改为集合？？同样，它显示打开一个ref光标；以及如何使用集合。可能重复的

PROCEDURE get_one_so (
     p_SO_CODE in String,
     RES OUT SYS_REFCURSOR
)
    AS
BEGIN
    OPEN RES FOR 

   SELECT
        so.so_code as SOCODE,
        cus.customer_code as CUSTOMERCODE,            
        cus.customer_name as CUSTOMERNAME,
        cus.email as EMAIL,            
        so.receiver_name as RECEIVERNAME,
        so.receiver_phone as RECEIVERPHONE,
        so.receiver_address as RECEIVERADDRESS,
        so.commment as COMMMENT,
        s.name as STAFFCREATE,     
                    to_char( so.CREATED_DATE,'dd/mm/yyyy') as CREATEDDATE,
        st.name as STAFFUPDATE,
        to_char(so.updated_date,'dd/mm/yyyy') as UPDATEDATE,
        sapp.name as STAFFAPPROVE,
       status,            
            so.reason_reject as REASONREJECT,
        so.payment as PAYMENY,
        to_char(so.send_date,'dd/mm/yyyy')   as SENDDATE,
        to_char(so.sended_date,'dd/mm/yyyy')   as SENDEDATE,
        so.staff_comment as STAFFCOMMENT
    FROM
        saleorders so join customer cus on so.customer_code = cus.customer_code
        left join saleorderDetail sod on so.so_code = sod.so_code
        left join staff s on so.staff_create = s.staff_code
        left join staff st on so.staff_update = st.staff_code
        left join staff sapp on so.STAFF_APPROVE = sapp.staff_code
    WHERE
        so.so_code IN (SELECT regexp_substr(p_so_code, '[^,]+', 1, LEVEL) 
                         FROM dual 
                      connect by regexp_substr(p_SO_CODE, '[^,]+', 1, level) is not null);
