Failed to create Oracle Text Index

Question

I want to create an text index for a single column for a table using this command:

CREATE INDEX    product_fulltext_index 
ON              products( computed_name )
INDEXTYPE IS    ctxsys.context

I tried to search but I have not found the solution yet, maybe the error message is too vague

This is my table design:

Error screenshot suggests that you're trying to create index on name column. Text of your question says that column name is computed_name. So, which one of them is it, really?

Anyway: if it is on

name Nvarchar2(500)
     ^
     |
     

then you can't do what you want because you can't create Oracle Text index on a column whose datatype uses the National Character set (NVARCHAR2). Why not? Because Oracle doesn't support it.

Either change column's datatype to e.g. VARCHAR2, or accept the fact that you can't have what you wanted.
