But if after checking above you still face error "ORA-00942: Table or view does not exist". Here are possible solutions:-

1. Check the object name
2. Qualify the object name
3. Check privileges
4. Refresh materialized view or synonyms
5. Check the database link
6. Re-compile invalid objects
7. Verify schema ownership
8. Check recycle bin
9. Check synonyms
10. Check object existence 

1. Check the object name

Verify that the table or view name is correct and matches the case sensitivity defined in the database. Ensure that there are no typographical errors or misspellings as this is a very common mistake for "ORA-00942: Table or view does not exist".

2. Qualify the object name

 If the object is in a different schema, make sure to prefix the object name with the appropriate schema name followed by a dot (e.g., SCHEMA_NAME.TABLE_NAME). This is especially important if you are accessing tables/views across multiple schemas and most cases are the reason for "ORA-00942: Table or view does not exist".

3. Check privileges

Confirm that the user has the necessary privileges to access the table or view. The user should have at least the SELECT privilege on the object or the necessary roles assigned and most cases are the reason for "ORA-00942: Table or view does not exist".

4. Refresh materialized view or synonyms

If the error is related to a materialized view or synonym, try refreshing the materialized view or recreating the synonym to ensure they are up to date and pointing to the correct object and most cases are the reason for "ORA-00942: Table or view does not exist".

5. Check the database link

 If the object is located in a different database accessed through a database link, verify that the database link is properly defined and functional. ORA-00942: Table or view does not exist

6. Re-compile invalid objects 

If the error occurs after a recent database upgrade or object modification, there may be invalid objects in the database. Run the following command as a privileged user to recompile all invalid objects: ALTER DATABASE COMPILE.

7.  Verify schema ownership

 Ensure that the object is owned by the expected schema. If it has been accidentally dropped or the schema has been renamed, the error may occur. Verify the object's existence in the correct schema.

8. Check recycle bin

If the table or view has been dropped recently, it might be present in the recycle bin. You can try restoring it from the recycle bin using the FLASHBACK TABLE or FLASHBACK DROP command. ORA-00942: Table or view does not exist

9. Check synonyms 

If the object is accessed through a synonym, verify that the synonym exists and points to the correct object. If necessary, drop and recreate the synonym.

10. Check object existence 

If none of the above solutions work, it's possible that the object has been mistakenly dropped. Double-check with other database users or administrators to confirm if the object still exists.
