I use the following SQL to concatenate several database columns from one table into one column in the result set:
SELECT (field1 + \'\' + field2 + \'\' + field
If you were using SQL 2012 or above you could use the CONCAT function:
SELECT CONCAT(field1, field2, field3) FROM table1
NULL fields won't break your concatenation.
@bummi - Thanks for the comment - edited my answer to correspond to it.
