Hi, We have a vendor product.

The application gives a unique table number for the tables in the database.
when we do import from user interface we can see the numbers right next to the table name.

I know some of them, but would like to generate from database a full list of the table name and its corresponding table number. But I searched all the tables in the database, and I cannot find where is the data stored.

I also did a select * from all_objects, there is a object_id column , but by comparing the data, it is not the table number we have.

Where else could I find the data possible? by the way the product is Powerschool.
I also searched in the data dictionary of their document, and I cannot find that either.

Thanks

I suspect that the desired data resides in application table because by default Oracle does not have a "unique table number".

Basically, you have a table (specific to the application) mapping a unique number to a table name. This mapping table, is itself, also a normal database table which I think should be found in all_tables.

Obviously, if you knew the owner (which is a column in all_tables) of that mapping table, that is, the technical database user of your application kernel, you could limit the scope of your search.

And I would also look for a table having a few number of columns (a mapping table)

Another way of searching, if both column names are known, could be by looking inside all_tab_columns

Yes, I think it should be a user table too .

Actually I did find one table named TableNumberMap. In the documentation of their database dictionary, it said this table contains legacy table names and corresponding number.
There is only one record in it. I guess it may be replaced by some other new tables, but just can find it anywhere in the database.

I suppose there is always this, if you can see it. But it is unreliable in that the numbers will as far as I know anyway change for export/import and drop/create etc.

Utility tools maybe? But I would never use this kind of object number for anything approaching a production piece of code.

This also relies on Oracle's definition of what an object is and this as we know changes when new technology comes along. For example, is a PARTITION and object?
