sql - PL SQL Oracle PLS-00103 : Encountered the symbol “CREATE”

Question

此代码接受邮政编码，城市和州的输入，然后将其插入到创建的地址表中。在插入数据之前，它将检查邮政编码是否已在表中，如果是，则调用procedure(error)以显示错误代码。

我收到错误代码pls-00103:尝试执行该代码时遇到符号“CREATE”。到目前为止，这是我的代码。感谢您的任何提前帮助。

drop table address;

create table address(zipcode NUMBER, city varchar2(30), state varchar2(20));

create or replace procedure error as
begin
  dbms_output.put_line('Error Zip Code already found in table');
end error;

declare
 zzip number;
 ccity varchar2(30);
 sstate varchar2(30);

create or replace procedure location(p_zipcode NUMBER,
                                     p_city varchar2,
                                     p_state varchar2) is
zip address.zipcode%type;
cit address.city%type;
st address.state%type;

begin
  select count(*) from address into zip where zipcode = zip;
  if any_rows_found then 
    error;
  else
  Insert into address values(zip, cit, st);
  end if;
end location;

begin
  select &zipcode into zzip from dual;
  select &city into ccity from dual;
  select &state into sstate from dual;
  procedure location(zzip, ccity, sstate);
end;

我不确定您要做什么，但是以下内容可能更接近您的想法:

drop table address;

create table address(zipcode NUMBER, city varchar2(30), state varchar2(20));

declare
 zzip number;
 ccity varchar2(30);
 sstate varchar2(30);

 procedure error is
 begin
  dbms_output.put_line('Error Zip Code already found in table');
 end error;

 procedure location(p_zipcode NUMBER, p_city varchar2, p_state varchar2) is
  zip_count   NUMBER;
 begin
  select count(*)
    into zip_count
    from address
    where zipcode = p_zipcode;

  if zip_count > 0 then 
    error;
  else
   Insert into address
     (zipcode, city, state)
   values
     (p_zipcode, p_city, p_state);
  end if;
 end location;

begin
 select &zipcode into zzip from dual;
 select &city into ccity from dual;
 select &state into sstate from dual;

 location(zzip, ccity, sstate);
end;
/

祝你好运。
