问题描述
我尝试了以下代码的不同方式,比如取出while或if,但是当我把两者放在一起时(if和while),我总是得到错误...
I tried the following code different ways, like by taking out the while or the if, but when I put both together (if and while), I always get the error at the end...
undefine numero
set serveroutput on
accept numero prompt 'Type # between 100 and 999: '
declare
i number:=1;
a char(25);
b char(1);
c varchar2(10);
d number;
begin
c := №
d := length(c);
b := substr(c, i, 1);
while i <= d loop
if b = '1' then
a:= a||'one ';
end if;
i := i+1;
end loop;
dbms_output.put_line('The number is '||a);
end;
/
错误:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 13
06502. 00000 - "PL/SQL: numeric or value error%s"
通过更改我声明变量的方式进行修复 ato:
a varchar2(2000);
推荐答案
是由于您将字符串声明为固定长度(比如说20),在你的代码中的某个时刻,你给它分配一个长度超过你声明的值的值。
is due to the fact that you declare a string to be of a fixed length (say 20), and at some point in your code you assign it a value whose length exceeds what you declared.
例如:
myString VARCHAR2(20);
myString :='abcdefghijklmnopqrstuvwxyz'; --length 26
将触发此类错误
