Change Password - (Oracle Misc)

In Oracle, users can change their password easily with the ALTER USER statement. This allows users to update their password to a new value without having to contact the database administrator directly.

Syntax

The syntax for changing a user's password in Oracle is as follows:

ALTER USER username
IDENTIFIED BY new_password;

Here, username is the name of the user whose password you want to change, and new_password is the desired new password.

Example

Here is an example of how to use the ALTER USER statement to change a user's password in Oracle:

ALTER USER john
IDENTIFIED BY secret123;

This will change the password for the user "john" to "secret123".

Output

The ALTER USER statement will not produce any output unless there is an error. If the statement is successful, you will simply see a message saying "user altered".

Explanation

In the above example, we are changing the password for the user "john" to "secret123". By using the ALTER USER statement with the IDENTIFIED BY clause, we are able to update the user's password without having to go through a database administrator.

Use

Changing a user's password is a common task in databases, and the ALTER USER statement makes it simple to do. This is especially useful for systems with a large number of users, as it allows users to reset their passwords themselves without adding extra work for the database administrator.

Important Points

• The ALTER USER statement can be used to change a user's password in Oracle.
• The IDENTIFIED BY clause is used to specify the new password.
• The ALTER USER statement does not produce any output unless there is an error.

Summary

In summary, changing a user's password in Oracle is a simple task that can be accomplished using the ALTER USER statement. This allows users to reset their passwords without having to contact a database administrator, which is especially useful for systems with a large number of users.
