根据你提供的错误信息,可能是因为你的数据库用户没有访问 DBMS_CRYPTO 包的权限。你可以尝试使用以下步骤来解决问题:
1. 确认你的数据库版本支持 DBMS_CRYPTO 包。DBMS_CRYPTO 包是在 Oracle 10g 及以后版本中引入的,如果你的数据库版本低于 Oracle 10g,将无法使用该包。
2. 确认 DBMS_CRYPTO 包已被正确安装。可以使用以下命令来检查 DBMS_CRYPTO 包是否存在:
```
SELECT * FROM all_objects WHERE object_name LIKE 'DBMS_CRYPTO';
```
如果该包不存在,请尝试使用以下命令来安装该包:
```
@?/rdbms/admin/dbmscrypto.sql
```
3. 确认你的数据库用户具有执行 DBMS_CRYPTO 包中函数的权限。可以使用以下命令来为当前用户授权:
```
GRANT EXECUTE ON DBMS_CRYPTO TO <username>;
```
其中,<username> 是你的数据库用户名。你也可以将权限授予其他用户或角色。
如果以上步骤都无法解决问题,可能是因为你的数据库用户没有访问系统表的权限。你可以尝试使用以下命令来为当前用户授权:
```
GRANT SELECT ANY DICTIONARY TO <username>;
```
其中,<username> 是你的数据库用户名。请注意,授予权限给任何用户都是有风险的,需要谨慎处理。

SQL> grant execute on dbms_crypto to SYSTEM; grant execute on dbms_crypto to SYSTEM * 第 1 行出现错误: ORA-00942: 表或视图不存在
这个错误提示说明Oracle数据库中不存在`dbms_crypto`包。可能原因是该数据库版本不支持`dbms_crypto`包,或者该包没有被正确安装。
可以使用以下命令检查当前数据库中是否存在`dbms_crypto`包:
```
SELECT owner, object_name, object_type
FROM dba_objects
WHERE object_name = 'DBMS_CRYPTO';
```
如果查询结果为空,则说明数据库中不存在该包。
如果需要使用`dbms_crypto`包,可以尝试升级数据库版本或者重新安装该包。需要注意的是,安装和升级数据库操作可能会对现有的数据库产生影响,建议在操作前进行备份并谨慎操作。
grant execute on dbms_crypto to system * ERROR at line 1: ORA-00942: table or view does not exist
The error "ORA-00942: table or view does not exist" indicates that the "dbms_crypto" object is not available in the current database schema.
This could be due to the following reasons:
- The object has not been created in the schema.
- The object has not been granted to the user executing the statement.
- The user executing the statement is not connected to the correct schema.
To resolve this error, you can try the following steps:
1. Check if the "dbms_crypto" object exists in the schema by running the command "DESCRIBE dbms_crypto" or "SELECT * FROM dbms_crypto". If it does not exist, you may need to create it.
2. Check if the user executing the statement has been granted access to the "dbms_crypto" object by running the command "SELECT * FROM user_tab_privs WHERE table_name = 'DBMS_CRYPTO'". If the user does not have access, you can grant the necessary privileges using the "GRANT" command.
3. Check if you are connected to the correct schema by running the command "SELECT * FROM user_users". If you are not connected to the correct schema, you can switch to the correct schema using the "ALTER SESSION SET CURRENT_SCHEMA" command.
