文档解释

ORA-24102: invalid prefix for generate_job_name

Cause: generate_job_name was called with a prefix longer than 18 characters or a prefix ending in a digit.

Action: Re-issue the command using a prefix no longer than 18 characters and not ending in a digit.

ORA-24102是一个通用错误，表明你在使用dbms_job.genrate_job_name()函数时，提供的前缀无效。

官方解释

GENERATE_JOB_NAME is an overloaded PL/SQL stored procedure of the DBMS_JOB package that returns a job name in the form of a VARCHAR2 string. GENERATE_JOB_NAME(prefix IN VARCHAR2) takes a single parameter, the prefix. The prefix must be a VARCHAR2 string between 1 and 16 characters in length.

简而言之，传入的前缀应该是1-16个字符的VARCHAR2字符串。

常见案例

常见的错误就是传入一个“空”前缀。在这种情况下，传入的字符串长度为零。

一般处理方法及步骤

要正确处理这个错误，只需确保传入的prefix参数为1-16个字符的VARCHAR2字符串即可。
