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经在表中,如果是,则调用 procedure(error) 以显示错误代码。
我收到错误代码 pls-00103:尝试执行代码时遇到符号“CREATE”。到目前为止,这是我的代码。感谢您提前提供任何帮助。
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);
