Question

id

我做错了什么？它正在开发其他程序，所以我很难确定究竟是什么阻止它工作。该过程也成功运行。有什么想法吗？感谢您的任何帮助。我确信我只是遗漏了一些非常明显的东西。

当我运行时：

SET SERVEROUTPUT ON
SET VERIFY OFF
DECLARE

v_idno          oilcust1.custid%TYPE :=&input_idno;
v_tank          oilcust1.tankcapacity%TYPE;
v_name          oilcust1.custname%TYPE;
v_state         oilcust1.custstate%TYPE;
v_city          oilcust1.custcity%TYPE;
BEGIN
        SELECT custid, custname, tankcapacity, custstate, custcity INTO v_idno, v_name, v_tank, v_state, v_city
                FROM oilcust1
                WHERE custid = v_idno;
        IF v_state = 'NC' THEN
           IF v_tank > 500 THEN
                IF v_city = 'Asheville' THEN
                                DBMS_OUTPUT.PUT_LINE(v_name || ' is a in an immediate city
                                and holds an above average tank.');
                ELSE
                                DBMS_OUTPUT.PUT_LINE(v_name || ' is not of priority at this time.');
                END IF;
            END IF;
         END IF;

END;
/
SET VERIFY ON
SET SERVEROUTPUT OFF

没有DBMS线。

我尝试复制同样的问题，问题仅在于会话的set serveroutput on。请参阅下面的代码，尝试使用Minimal, Complete, and Verifiable example

复制您的问题

File: p1.sql

declare
v_empno integer :=&input_empno;
v_ename varchar2(10);
begin
select ename into v_ename from emp where empno = v_empno;
 if v_empno > 7700 then
    if v_ename is not null then
        dbms_output.put_line(v_ename);

     else
        dbms_output.put_line('empno doesn''t exist');
    end if;
 else
 dbms_output.put_line('please enter empno < 7700');
 end if;
end;
/

没有set serveroutput on;

的执行

服务器输出

之后

SQL> set serveroutput on;

Enter value for input_empno: 7782
old   2: v_empno integer :=&input_empno;

dbms_output.put_line无法在这个简单的嵌套if中工作
