Pl SQL Oracle PLS-00103: 遇到符号 "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 table 创建的地址中。在插入数据之前，它将检查邮政编码是否已经在 table 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：尝试执行代码时遇到符号 "CREATE"。到目前为止，这是我的代码。提前感谢您的帮助。

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。

我不知道我是否理解正确你的问题，但我想解决一些更正来回答你的问题

First, if you are going to create a procedure/function, do it in a separate worksheet then compile it. Dont compile it together with other anonymous blocks because most of the time, if you dont end your other blocks with '/', errors will surely generate.
Second, your DECLARE statement is misplaced, if you are going to make an anonymous block, make sure DECLARE, BEGIN and END are in line, dont create a procedure/function inside an anonymous block.
Third, you are declaring variables in your procedures and using them but doesnt have an initial value, so it will just pass a null value to the DML statement in your procedure. just use the parameter directly.
Fourth, avoid creating a procedure that only contains dbms_output.put_line. Its silly.
Lastly, your anonymous block that should be calling your procedure, uses '&', please avoid using '&' inside pl/sql as '&' is a feature in SQL*Plus and doesnt have any meaning in PL/SQL, instead, you can use ':' as for binding variables. But you use '&' not in binding variables so you should remove that;

试试这个：

drop table address;

 /

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

 / 

create or replace procedure location(p_zipcode NUMBER, 
                                     p_city varchar2,    
                                     p_state varchar2) is

zip address.zipcode%type;


begin
  select count(*) 
    from address 
    into zip 
    where zipcode = p_zipcode 
             and city =p_city 
                and state = p_state;

  if zip > 0 then 
   dbms_output.put_line('Error Zip Code already found in table');
  else
  Insert into address values(p_zipcode, p_city, p_state);
  end if;
end location;

/


begin

 location(:zzip, :ccity, :sstate);

end;
