This will concatenate the Field1 and Field2 together as Field3:

SELECT Field1, Field2, (Field1 + Field2) AS Field3 FROM myTable

this should do:
select field1, field2, field1 + cast(field2 as varchar(20)) as field3 
  from yourtable

If you need a space between them you can do this:
SELECT Field1, Field2, (Field1 + ' ' + Field2) AS Field3 FROM myTable

Actually Angellll is right you'll need to CAST the INT field first.

None of the solutions posted return 2 columns, they all return 3 columns (field1, field2 and field3), so why don't you post your query and we can point out the problem, instead of spending all day guessing.

the suggested code was just "repeating" the field1 and field2 for "demonstration"...
select field1 + cast(field2 as varchar(20)) as field3 
  from yourtable

you will need to cast or convert the int to a varchar to make it work
concatenation of a varchar field and an int field without cast or convert will throw an exception always

    'returnedcolumnname' = stringfield + ' ' + convert (varchar, intfield)
