将一个表的每一列作为一行插入到另一个表中

Question

I have one table with the following columns:

c1, c2, c3, c4, c5

And another table with the following columns:

id, column_info

...there are some other columns but here's the main problem.

For each column in table 1, I'd like to insert a row in table 2, like this:

id | column_info
---|------------
 1 | c1
 2 | c2
 3 | c3
 4 | c4
 5 | c5

Is this possible as an SQL statement?

Answer 1

INSERT INTO Some_Table (id, column_info)
SELECT id, c1 UNION ALL
SELECT id, c2 UNION ALL
SELECT id, c3 UNION ALL
SELECT id, c4 UNION ALL
SELECT id, c5
