Easy Loader creates Additional tables in Oracle 10G

Question

Hellow everybody
I have uploaded a MapInfo TAB file into OracleSpatial 10G, using EasyLoader utility in MapInfo prof 8.0. To my surprise I found some additional tables created apart from the loaded spatial table. They are
BIN$3K6Am/kGSH6qQR1cSxw1yQ==$0
BIN$uL2fNlZOTHGh1erc17qOIw==$0
BIN$/0NNB59pSo6Bl8t/LzxsQg==$0
BIN$onUlr5+ASVieMUvi/y36rA==$0
What are these tables? and why are they created?
Regards
Sunny

Answer 1

Those tables are not created by Easyloader.- at least not directly.
Starting with 10g, the database now contains a "recycle bin" much like the NTFS file system. Whenever you drop a table, that table does not really get dropped: it gets renamed to objects with obscure names (like BIN$onUlr5+ASVieMUvi/y36rA==$0).
You can see the actual names of the objects in your recyble bin by doing:
SQL> select * from recyclebin;
And restore (undrop) a table by doing, for example:
SQL> flashback my_table to before drop;
So, either you dropped some tables before (or after) running easyloader, or possibly easyloader created some tables which it then dropped.
Oh, and I forgot. To clear out your bin, do:
SQL> purge recyclebin;
If you intend to use this feature, I strongly recommend that you first read the admin manual first (section titled "Using Flashback Drop and Managing the Recycle Bin") - available here: http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10739/tables.htm#sthref2006
