mysql merge two columns into one column

I am trying to merge two columns into one column. Not sure what I am doing wrong..


here what I have
id stuff something
1 2 5
0 2 1
2 2 5
3 2 5
1 2 4

What I want it to combine into

THIS IS WHAT I WANT IT TO LOOK LIKE //////////
stifething
25
21
25
25
24

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
What I tried...

INSERT INTO test3 (combined)
SELECT  test2column2  FROM test2
UNION ALL
SELECT two FROM test

Code (markup):

And what this did...

stifething
2
5
2
1
2
5
2
5
2
4


Any pointers or suggestions would greatly be appreciated.

 

I figured this out.. It was as simple as... update test set third = concat(one,two);
