Question

如何在将数据插入表之前对存储过程中的表执行删除操作？

create or replace procedure proc_test is
begin
delete * from table1

insert into table1
select * from table2
end proc_test;

似乎没有用，语法有什么问题？错误是

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

啊，问题在于缺少分号！这工作

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

删除时不需要*：delete from table1。此外，如果要删除所有记录，请考虑truncate（但是，truncate是ddl命令，因此您将无法回滚）
