如何刪除數據並將其插入存儲過程中的同一個表中？

Question

在將數據插入表之前，如何在存儲過程中對錶進行刪除操作？

create or replace procedure proc_test is 
begin 
delete * from table1 

insert into table1 
select * from table2 
end proc_test; 

似乎沒有工作，語法有什麼問題？該錯誤是

ERROR at line 8: PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following: 

    begin case declare end exception exit for goto if loop mod 
    null pragma raise return select update while with 

    << close current delete fetch lock insert 
    open rollback savepoint set sql execute commit forall merge 
    pipe 
6. select * from table1 
7. 
8. end proc_test; 

Answer 1

嗯，問題是缺少分號！此作品

create or replace procedure proc_test is 
begin 
delete * from table1; --semicolon here 

insert into table1 
select * from table2; --semicolon here 
end proc_test; 

Answer 2

不需要*中刪除：delete from table1。此外，如果要刪除所有記錄，請考慮truncate（但是，truncate是ddl命令，因此您將無法回滾）
