How to switch users from oracle

How to switch Oracle users

In Oracle databases, switching users involves two common methods: ALTER SESSION and CONNECT.

Method 1: ALTER SESSION

• Connect to the Oracle database.
• Switch users using the following syntax:

 <code>ALTER SESSION SET CURRENT_USER = '';</code>

• For example: To switch to user "hr":

 <code>ALTER SESSION SET CURRENT_USER = 'hr';</code>

Method 2: CONNECT

• Disconnect from the current session.
• Reconnect to the database using the following syntax:

 <code>CONNECT / AS SYSDBA;</code>

• If the new user is SYSDBA, use "AS SYSDBA". Otherwise, "AS SYSDBA" is omitted.
• For example: To connect to user "hr" as SYSDBA:

 <code>CONNECT hr/hr_password AS SYSDBA;</code>

Notes:

• When switching users, all settings and variables in the session are reset.
• Only users with the appropriate permissions can switch users.
• If switching to a new user fails, the session will be disconnected.
