Cannot commit DML scripts (DELETE, INSERT, UPDATE)

[dnlw07]

Describe the bug
When I execute Insert or Delete command then the change is not applied in Oracle DB.
After script execution I use COMMIT to finish transaction.

No errors are returned during script insert, delete, and commit execution.

I'm also having this problem. When I execute an update/insert/delete query like:

update db.sample_table
        set client_name = 'Example' 
        where id = '1';

It run with success with the message: 1 rows were affected, but the change it's not represented on table. So I run COMMIT in a separated query, and the message is:

No Data

And the table is still with the previous value.
If I run something like:

update db.sample_table
        set client_name = 'Example' 
        where id = '1';
commit;

I get the following message:
ORA-00933: SQL command not properly ended
