我有一个下面的包，它给出了错误
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
请告诉我这里出了什么问题。

答案 0 :(得分：5)
您正在尝试为PL / SQL变量赋值，该变量不够大。例如，你有
...
Lv_rqst_id NVARCHAR2(20);
...
然后：
...
SELECT fnc_gen_request_id
INTO Lv_rqst_id
FROM dual;
....
我不知道fnc_gen_request_id是什么或返回的是什么，但是在你的代码中查看这种赋值并尝试测试它或包装在BEGIN ... EXCEPTION .. END结构中以获得线索。
答案 1 :(得分：3)
除了@Aitor提到的潜在fnc_gen_request_id返回大小问题之外，您还可以将一个值放入调用者无法处理的OUT参数中的一个。例如，当您将最多4000个字符放入Pout_err_msg时，虽然这只会在遇到异常时出现问题，但Pout_Rqst_Id或Lv_rqst_id可能更有可能。您可能还想检查您是否一直使用VARCHAR和NVARCHAR。 （顺便提一下，Pout_err_cd应该被声明为数字吗？）
答案 2 :(得分：1)
您正试图在字符串（缓冲区）变量中插入太多字符。
以下两个方框都会引发ORA-06502: PL/SQL: numeric or value error: character string buffer too small。您的问题是这些简单案例的变体。
declare
str varchar2(2); /* Only room for two characters. */
begin
select 'foo' into str from dual; /* Three is one too many. */
end;
/
declare
str varchar2(2); /* Only room for two characters. */
begin
str := 'foo'; /* Three is one too many. */
end;
