ORA-32021: parameter value longer than string characters

文档解释

ORA-32021: parameter value longer than string characters

Cause: An attempt was made to alter a parameter value but the number of characters in the parameter value was longer than the allowed maximum. For a list parameter, one of the values in the list was longer than the allowed maximum.

Action: Reduce the parameter value length and retry the command. For the DISPATCHERS parameter, use listener aliases to reduce value length.

ORA-32021: parameter value longer than string characters是Oracle数据库的一种通用错误，表示尝试将参数值插入某个字符串中时，此参数值的长度超出了该字符串的有效长度。

官方解释

常见案例

my_string VARCHAR2(10);

my_string = ‘This is a test string’;

my_string = ‘This is greater than 10’; — ORA-32021

一般处理方法及步骤

1.查找触发错误的SQL语句。

2.确定参数值和字符串长度是否符合要求。

3.如果要求不符，则根据查找到的SQL语句，对相应的参数做出调整。

4.重新执行经调整后的SQL语句。
