选择更多列

Question

The question is a little crazy. I have a table in MySQL with columns 'id', 'from' and 'to'. I want the select to perform on this table and I need more columns for subsequent tasks.

An example:

DROP TEMPORARY TABLE IF EXISTS bla;
CREATE TEMPORARY TABLE bla (SELECT *, (SELECT id) AS test FROM flug WHERE flug_id >= 1 AND flug_id < 11);
UPDATE bla SET test = 100000;
SELECT flug_id, test FROM bla;

Are there other ways to create further columns?

With best regards

Couldn't you just do?

SELECT flug_id, 100000 as test 
FROM flug as f
WHERE flug_id >= 1 
  AND flug_id < 11;
