Hi, I am trying to retrieve the emp_id from my table by using a combination on first and last name, actually in my app i m allowing the user to select name from a list box, and filling the list box from the user_details table from first and last name column with a space in between, i.e. "Mohit Roy", if the user select the name i want my app to do some operation using the emp_id of that name, please help me to write the query which can retrieve the emp_id using first and last name column with a space between in it. Thanks in advance.

Mysql:

SELECT CONCAT_WS(' ', `name`, `surname`) AS `emp_id` FROM `employees`

PostgreSQL:

SELECT name || ' ' || surname FROM employees

SQLServer 2005:

SELECT name + ' ' + surname FROM employees

check this ;)

don't have SQLServer 2005 near. In MySQL following works:
SELECT * FROM `gifts` WHERE CONCAT_WS(' ', `from`, `ts`) = '1 1'

try:
SELECT (name + ' ' + surname) AS emp_id FROM employees WHERE emp_id = 'Mohit Roy'
