InitializeDBObjects(Conn, Comm)'This is a
Function to set the Connection and the
'Command Object
Comm.Connection = Conn

Firstly dont use a * in your select  statment, this is very bad practice for
several reasons, but to do what you want do...

select FName + ' ' + LName as fullname from library_Author

(Along with any other columns that you require)

Since there were only 3 Fields I used *
But then as you said Its a Bad Practise thanx a Lot
for the Solution.

Once other thing you are probably best doing as well is using the IsNull
operator, any nulls in either column will make the whole statement return a
null (A NULL + a string  always = NULL)...

select IsNull(FName, '') + ' ' + IsNull(LName, '') as fullname

That is assuming you are using MS SQL?
