Question

创建一个名为insert_credit的过程，以通过将5个输入作为参数传递到credit_card表中。

程序名称：insert_credit

输入参数：credit_id with data type as number,credit_card_number with data type as varchar,credit_card_expire with data type as varchar,holder_name with data type as varchar and card_type with data type as varchar

使用的表：credit_card

我写了这个：

CREATE OR REPLACE PROCEDURE insert_credit(
       p_credit_id IN credit_card.credit_id%TYPE,  
       p_credit_card_number IN credit_card.credit_card_number%TYPE,  
       p_credit_card_expire IN credit_card.credit_card_expire%TYPE,  
       p_holder_name IN credit_card.holder_name%TYPE,  
       p_card_type IN credit_card.card_type%TYPE)  
IS  
BEGIN  

   INSERT INTO credit_card ("credit_id", "credit_card_number",   "credit_card_expire", "holder_name","card_type")   
  VALUES (p_credit_id, p_credit_card_number,p_credit_card_expire,  
 p_holder_name,p_card_type);  

  COMMIT;  

END;  
/

执行时，我得到：

“警告：由于编译错误而创建的过程。”

Answer 1

如果要调试过程，可以像匿名块一样运行它，并声明所有输入参数。

/*CREATE OR REPLACE PROCEDURE insert_credit(
       p_credit_id IN credit_card.credit_id%TYPE,  
       p_credit_card_number IN credit_card.credit_card_number%TYPE,  
       p_credit_card_expire IN credit_card.credit_card_expire%TYPE,  
       p_holder_name IN credit_card.holder_name%TYPE,  
       p_card_type IN credit_card.card_type%TYPE)  
IS  */
declare
p_credit_id credit_card.credit_id%TYPE := somevalue
...
..
...
P_card_type

BEGIN  

   INSERT INTO credit_card ("credit_id", "credit_card_number",   "credit_card_expire", "holder_name","card_type")   
  VALUES (p_credit_id, p_credit_card_number,p_credit_card_expire,  
 p_holder_name,p_card_type);  

  COMMIT;  

END;

现在，您将能够获得出现错误的行。程序段运行无误后，您可以删除声明部分并取消注释注释的代码。

Answer 2

CREATE OR REPLACE
PROCEDURE insert_credit(
credit_id IN credit_card.id%TYPE,
credit_card_number IN credit_card.card_number%TYPE,
credit_card_expire IN credit_card.card_expire%TYPE,
holder_name IN credit_card.name%TYPE,
card_type IN credit_card.cc_type%TYPE) AS
BEGIN
INSERT INTO credit_card(id,card_number,card_expire,name,cc_type)
VALUES(credit_id,credit_card_number,credit_card_expire,holder_name,card_type);
END insert_credit;
/
