grant execute on dbms_crypto to system * ERROR at line 1: ORA-00942: table or view does not exist怎么解决

这个错误提示表明当前用户(可能是system)没有DBMS_CRYPTO包的执行权限,或者包不存在。
首先,确认该包是否存在于数据库中:
```
SELECT object_name, object_type
FROM dba_objects
WHERE object_name = 'DBMS_CRYPTO';
```
如果结果集为空,则说明该包并不存在,你需要安装该包。如果结果集中有该包,则需要授予执行权限给当前用户:
```
GRANT EXECUTE ON DBMS_CRYPTO TO system;
```
请注意,如果当前用户不是SYS或者拥有DBMS_CRYPTO权限的用户,则需要使用SYS用户或者该用户授予EXECUTE任何包的权限。
另外,如果你使用的是Oracle Database 11g Release 1或更早版本,则DBMS_CRYPTO包可能不存在。在这种情况下,你需要升级到Oracle Database 11g Release 2或更高版本才能使用该包。

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。
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.
