Question

从oracle查询时出现以下错误：

ORA-06502：PL / SQL：数字或值错误：字符串缓冲区太小 ORA-06512：在第1行

这是我的查询：

with my_clob as ( select ID,SUBJECT,EMAIL_LAYOUT,EMAIL_SENDER_TYPE from BMS_EMAIL_TEMPLATE where ID = 26 ) select ID,SUBJECT,EMAIL_SENDER_TYPE, dbms_lob.substr(EMAIL_LAYOUT, 4000, (level - 1) * 4000 + 1) AS EMAIL_LAYOUT from my_clob connect by level <= ceil(dbms_lob.getlength(EMAIL_LAYOUT) / 4000)

任何人都可以帮助我在这里我想念的东西吗？

Answer 1

请提供表格BMS_EMAIL_TEMPLATE的描述吗？ EMAIL_LAYOUT是克隆还是大型varchar2？

我无法使用以下代码重现您的错误

with bs as (    
    select to_clob( lpad('x',37,'x')) f1 from dual),
bs1 as (select f1||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 as f1 from bs),
bs2 as (select f1||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 as f1 from bs1),
bs3 as (select f1||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 as f1 from bs2),
cl as ( select f1||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 ||f1 as f1 from bs3),
my_clob AS (
    SELECT
        26 id,
        'subj' subject,
        f1 email_layout,
        length(f1) email_length,
        'est' email_sender_type
    FROM
        cl
) SELECT
    id,
    subject,
    email_sender_type,
    email_length,
    dbms_lob.substr(email_layout,4000, (level - 1) * 4000 + 1) AS email_layout
  FROM
      my_clob
CONNECT BY
    level <= ceil(dbms_lob.getlength(email_layout) / 4000);

从Oracle Clob数据获取错误
