Concatenating output from a SELECT statement is a pretty basic thing to do in SQL. The main ways to perform this would be to use either the CONCAT() function, the || operator or the + operator. It really all depends on which version of SQL you are using. The following examples use T-SQL (MS SQL Server 2005) so it uses the + operator but other SQL versions have similar syntax.

If you wanted to join two fields together for a full name:

SELECT (lname + ', ' + fname) AS Name
FROM tblCustomers

To add some static text to a value:

SELECT (lname + ' - SS') AS Name
FROM tblPlayers
WHERE PlayerPosition = 6

Or to select some text and an integer together:

SELECT (lname + cast(playerNumber as varchar) AS Name
FORM tblPlayers

Remember that when you do "cast(playerNumber as varchar)" it is interpreted as "cast(playerNumber as varchar(10))". This could potentially cause problems for very large numbers.
