SQL Execute Insert or Update based if the Data is already in the Table

is it possible to execute a query that inserts the Row if the ID don't exist and Update the Row if the ID already exists in a single sql statment?

i mean not using stored procudures just plain SQL.

i already doing LoadRecord and if noone returned then insert and if any record is returned then update.

but i wanted to know if there is any way to do it without hit开发者_C百科ting on the DB server Twice.

The ID field is an integer Primary Key that is not an auto incriment.

thanks
