single upsert statement

Hi All,

I want to update/insert data in a table based on the value of a primary column

Ex:

Create Table Table1
(
AccountID INT,
LastName Varchar(10),
FirstName Varchar(10),
Email Varchar(50),
Address1 Varchar(10),
Address2 Varchar(10),
City Varchar(20),
State Varchar(20),
Country Varchar(20)
)

Create Table Table2
(
AccountID INT,
LastName Varchar(10),
FirstName Varchar(10),
Email Varchar(50),
Address1 Varchar(10),
Address2 Varchar(10),
City Varchar(20),
State Varchar(20),
Country Varchar(20)
)

Table1 will get new data or updates from another process. Now i need a SQL to update/insert Table2 if the AccountID is existing then i have update all the remaining fields if accountID is not found then i have to insert new record in Table2.

Is there simple way of doing this?

Thanks a  lot for your time.

Eshwar.
