ORA-64203: Destination buffer too small to hold CLOB data after character set conversion. ORACLE 报错 故障修复 远程处理

文档解释

ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.

Cause: An attempt was made to convert CLOB to CHAR, where the LOB size was bigger than the buffer limit for CHAR types or the CHAR buffer was not big enough to hold all data after character set conversion.

Action: Do one of the following:
* Make the LOB smaller before performing the conversion. for example, by using SUBSTR on CLOB
* Use DBMS_LOB.SUBSTR to convert CLOB to CHAR.

官方解释

ORA-64203: 在字符集转换后,目标缓冲区太小无法容纳 CLOB 数据。

这是一个缓冲区大小错误,发生在将CLOB数据从一个字符集转换为另一个字符集时。分配的缓冲区空间太小无法存储结果。

常见案例

假设在处理大型文本数据时,使用字符集转换的语法操作表中的CLOB列,出现以下错误:

ERROR at line 1:

ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.

一般处理方法及步骤

1.正确识别和诊断错误原因如何出现此错误。

2.如果错误是由缓冲区限制引起的,可以尝试增加缓冲区大小。

3.可以尝试将字符串截断,以便它容易处理,然后将结果连接到一起,以及强制改变要处理的字符串的长度。

4.考虑重新审查代码,以检查是否有更好的方法来处理CLOB字段而避免任何缓冲区限制问题。
