[sql] How to copy a row from one SQL Server table to another

I have two identical tables and need to copy rows from table to another. What is the best way to do that? (I need to programmatically copy just a few rows, I don't need to use the bulk copy utility).

Alternative syntax:

INSERT tbl (Col1, Col2, ..., ColN)
  SELECT Col1, Col2, ..., ColN
  FROM Tbl2
  WHERE ...

The select query can (of course) include expressions, case statements, constants/literals, etc.

INSERT INTO DestTable
SELECT * FROM SourceTable
WHERE ... 

works in SQL Server

Jarrett's answer creates a new table.

Scott's answer inserts into an existing table with the same structure.

You can also insert into a table with different structure:

INSERT Table2
(columnX, columnY)
SELECT column1, column2 FROM Table1
WHERE [Conditions]

SELECT * INTO < new_table > FROM < existing_table > WHERE < clause >
