All we need is an easy explanation of the problem, so here it is.
I’m trying to learn about indexes in Oracle 18c.
As a novice, it’s occurred to me that it might be interesting to view the actual data that’s in a function-based index:
create index sidewalk_endpoint_list_idx on my_owner.sidewalks(my_owner.endpoint_list(shape),objectid);
Is there a way to SELECT an index’s data in a query?
select * from sidewalk_endpoint_list_idx
That might be a silly question. Maybe indexes aren’t stored in tables. But I thought it was worth asking, just so I can learn.
How to solve :
I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
You can’t, but you can select it from the table:
select my_owner.endpoint_list(shape),objectid,rowid from my_owner.sidewalks;
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
