How to do this self-join??

al
Greetings,

Would be thankful for your kind help. I have a table (Northwind
employees table). In the employees table, a column called ReportsTo
which lists the EmployeeID, int data type, of the manager of an
employee.This ReportsTo column is basically the EmployeeID column:

EmployeeID Title ReportsTo FirstName SecondName ......
......
1 Manager 4 Steven Buchan
2 Sale Rep. 1 Janet Leverling
3 Clerk 1 Ropert King
4 Presedint Null Andrew Fuller

My question is how can I get the column ReportsTo to include first and
second name, instead of numbers (employeeid).

What I want is something like this(firsname, lastname OR lastname,
firstname for the ReportsTo columen):

EmployeeID Title ReportsTo FirstName SecondName
.... ...
1 Manager Andrew Fuller Steven Buchan
2 Sale Rep. Steven Buchan Janet Leverling
3 Clerk Steven Buchan Ropert King
4 Presedint Null Andrew Fuller

SELECT E1.EmployeeID,
E1.Title,
E2.FirstName + ' ' + E2.LastName AS ReportsTo,
E1.FirstName,
E1.LastName
FROM Northwind..Empl oyees AS E1
LEFT OUTER JOIN
Northwind..Empl oyees AS E2
ON E2.EmployeeID = E1.ReportsTo

Jag,

Thanks for your help. Does this solution work with CommandBuilder in ADO.NET?

I'd like to subclass int to support list access, treating the integer as if it were a list of bits. Assigning bits to particular indices involves changing the value of the integer itself, but changing 'self' obviously just alters the value of that local variable. Is there some way for me to change the value of the BitSequence object itself?...

The Python FAQ 1.4.5 gives 3 reasons for explicit self (condensed version): 1. Instance variables can be easily distinguished from local variables. 2. A method from a particular class can be called as baseclass.methodname(self, <argument list>). 3. No need for declarations to disambiguate assignments to local/instance variables.
