t-sql

I need to take data from one table and import it into another table. In pseudocode, something like this: For Each row in table1 If row.personid is in table2 then update table2.row Else insert row into table2 End If Next What is the best way to do this in T-SQL? As I understand it T-SQL doesn't support For Each..Next, so what alternatives do I have?
