ORA-00955: name is already used by an existing object

Symptom

You are creating a table in the Oracle but you are getting below error.

create table aracici;
ERROR at line 1:
ORA-00955: name is already used by an existing object

Solution

You are getting the error because the respective database object (table, index, view, synonym or cluster) are already existed.

So, you need to enter a different name (should be the safest way) or you can drop/modify the database object so that you can re-use it again.
