Plsql 使用INSERT语句输入新数据时出错-重复密钥？

plsql oracle11g

Plsql 使用INSERT语句输入新数据时出错-重复密钥？,plsql,oracle11g,Plsql,Oracle11g,我正在尝试运行我编写的以下存储过程以满足此要求：编写一个过程ProcedureName（p\u snum，p\u CallNum）以向课程添加/注册学生。但是，在执行此操作时，我在Oracle Developer中遇到以下错误，我不确定如何纠正此问题。这可能是显而易见的，但我想了解正在发生什么来改进我的技术： Error starting at line : 17 in command - Execute ThreeOne(500,10500) Error report - ORA-00001

我正在尝试运行我编写的以下存储过程以满足此要求：编写一个过程ProcedureName（p\u snum，p\u CallNum）以向课程添加/注册学生。

但是，在执行此操作时，我在Oracle Developer中遇到以下错误，我不确定如何纠正此问题。这可能是显而易见的，但我想了解正在发生什么来改进我的技术：

Error starting at line : 17 in command -
Execute ThreeOne(500,10500)
Error report -
ORA-00001: unique constraint (CORY.SYS_C0012641) violated
ORA-06512: at "CORY.THREEONE", line 9
ORA-06512: at line 1
00001. 00000 -  "unique constraint (%s.%s) violated"
*Cause:    An UPDATE or INSERT statement attempted to insert a duplicate key.
           For Trusted Oracle configured in DBMS MAC mode, you may see
           this message if a duplicate entry exists at a different level.
*Action:   Either remove the unique restriction or do not insert the key.

任何指针都将不胜感激。

经过研究，我意识到我实际上是在尝试插入已经存在的重复数据。此外，我意识到我对参数类型使用了错误的赋值，并且不允许为变量pass使用适当的空间量和数据类型

谢谢大家的帮助
