Dear Learner,

Hope you are doing good.

The possible reason of the error is that you tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn't reference the table by the schema name.

Please try with the below options:

(i) If this error occurred because the table or view does not exist, you will need to create the table or view.
You can check to see if the table exists in Oracle by executing the following SQL statement:

SELECT *
FROM all_objects
WHERE object_type IN ('TABLE','VIEW')
AND object_name ='TABLE_NAME';


(ii) If this error occurred because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant you the appropriate privileges to this object. The syntax for granting privileges on a table in Oracle is:

GRANT privileges ON object TO user;

(iii) If this error occurred because the table/view belongs to another schema and you didn't reference the table by the schema name, you will need to rewrite your SQL to include the schema name.

Please try with the above options and let us know if the issue persist.

I will wait for your response.
