Answer 1

The database object naming rules explain the namespaces, including:

Within a namespace, no two objects can have the same name.

The following schema objects share one namespace:

• Packages
• Private synonyms
• Sequences
• Stand-alone procedures
• Stand-alone stored functions
• Tables
• User-defined operators
• User-defined types
• Views

The ORA-00942 error is saying there is no table or view with that name, so the ORA-00955 error must be coming from a different object type from that list.

Query the data dictionary to see what exists:

select owner, object_type
from all_objects
where object_name = 'TRANSCLAIMCOUNTS_ITG401223';

(Note that the name is in uppercase in the data dictionary, as you are not using a quoted identifier; you won't find the object causing your issue if you look for object_name = 'transclaimcounts_ITG401223' . That is explained in the same documentation.)

Then you will either have to drop or rename that; or pick a different name for your new table. We can't advise you which action to take, it's your schema. But don't drop anything unless you're 100% sure it should not exist, obviously.
