How to combined first_name and last_name using sql query?

There are two columns in database as name FIRST_NAME and LAST_NAME.i want to join both the name and display in single column. The query which is used by me is give开发者_开发问答n below but it gives error as Incorrect syntax near 'NAME'.

Modify the query:

SELECT [CREATED_ON], MUD.PK_ID AS USER_ID, 
(MUD.FIRST_NAME + ' ' + MUD.LAST_NAME NAME) 
AS NAME FROM USER_TABLE

---

Remove the erroneous 'NAME'. e.g.

SELECT [CREATED_ON], MUD.PK_ID AS USER_ID, (MUD.FIRST_NAME + ' ' + MUD.LAST_NAME) 
AS NAME FROM USER_TABLE

---

SELECT 
   [CREATED_ON], 
   MUD.PK_ID AS USER_ID, 
   (MUD.FIRST_NAME + ' ' + MUD.LAST_NAME) AS [NAME]
FROM
   USER_TABLE

The parentheses around the expression MUD.FIRST_NAME + ' ' + MUD.LAST_NAME are optional.
