Question

我想仅使用一个过程将值插入EVENT表和EventCost表中。

事件的PK为EventID，它是FK表的EventCost。我尝试对SCOPE_IDENTITY()使用EventID，但仍然无法创建该过程。

2）我是否需要在标头中声明v_EventID两次？（一个用于事件表，一个用于eventCost表）

CREATE OR REPLACE PROCEDURE PRC_ADD_OVER_BUDGET_EVENT
(  V_eventID IN VARCHAR
  ,V_EventType IN VARCHAR
  ,V_EventBudget IN NUMBER
  ,V_organizerID IN VARCHAR
  ,v_CostID IN VARCHAR
  ,v_FoodBeverage IN NUMBER
  ,v_wine IN NUMBER 
  ,v_Decoration IN NUMBER
  ,v_rentalfee IN NUMBER
  ,v_facility IN NUMBER
  ,v_EventID IN VARCHAR)

AS
BEGIN

INSERT INTO Event 
values 
(next_eventid_seq,null,v_eventbudget,null,null,null,v_organizerID)


INSERT INTO EventCost 
values 
(next_Costid_seq,v_FoodBeverage,v_Wine,v_Decoration,v_RentalFee,v_Facility,SCOPE_IDENTITY())

End;
/

Answer 1

使用returning into子句：

CREATE OR REPLACE PROCEDURE PRC_ADD_OVER_BUDGET_EVENT
(  V_eventID IN VARCHAR
  ,V_EventType IN VARCHAR
  ,V_EventBudget IN NUMBER
  ,V_organizerID IN VARCHAR
  ,v_CostID IN VARCHAR
  ,v_FoodBeverage IN NUMBER
  ,v_wine IN NUMBER 
  ,v_Decoration IN NUMBER
  ,v_rentalfee IN NUMBER
  ,v_facility IN NUMBER
  ,v_EventID IN VARCHAR)

AS
  event_ID varchar2(64);
BEGIN

INSERT INTO Event 
values 
(next_eventid_seq,null,v_eventbudget,null,null,null,v_organizerID) returning eventID into event_ID;


INSERT INTO EventCost 
values 
(next_Costid_seq,v_FoodBeverage,v_Wine,v_Decoration,v_RentalFee,v_Facility,event_ID);

End;
/

P.S。还有一些注意事项：

使用varchar2数据类型代替varchar。
插入时，请提供要插入的列的名称：insert into Event (col1, col2, col3, ...)。如果您的表结构发生了更改，insert语句仍将起作用。
