Invalid column ora-00904

Question

Good Morning,
I know you have seen this all before but I keep getting this error above and can't seem to locate this error in the code. I simplified the code to be able to id it more easily but no luck.
Thanks in advance.

cursor c1 is select owner from dba_tables where owner = 'X';

sql_stmt := 'select table_name, index_name, column_name, column_position
from dba_ind_columns
where table_owner= '||c1_rec.owner;
execute immediate sql_stmt;
end loop;
end;

Good Evening Everyone,
After I had left work and was cruising home on my Harley here in the Washington DC area that thought had occurred to me about those quotes also. I believe that is the solution to the problem. The column name is without quotes. I will try this tommorrow and let you know how it turns out. I know there are alot of easier ways to get the data I need from the tables but how is one to learn if you don't take the rough road once in a while? I am just creating a general script to identify all the user tables who have index columns and what position they are. This information is important to me for database tuning purposes. Once I have these indexes they will be readily available for me to use in perfomrance tuning efforts in the sql scripts as hints. Such as FF_S(table_name index_name). It is just a pain to keep running a short script again and again.
Thanks to everyone who responded.
