Re: INSERT ... SELECT DISTINCT - Doesn't work...

I'm sorry. In fact, I was not so carefull with my analisis and the
example I provided you was not exactly like the real problem.

First, I have failed to use the same type in the columns (integer in one
relation, varchar in the other). I think this was the major problem. To
make the example more realistic:

user_operations (
user_id integer,
user_name varchar,
user_operation varchar)

CREATE TABLE users (
user_id varchar,
user_name varchar);

the column user_id from the relation users was with the wrong type
(varchar). I changed it to integer (as user_operations), and the INSERT
works well.
