How to DROP multiple columns with a single ALTER TABLE statement in SQL Server?

Question

I would like to write a single SQL command to drop multiple columns from a single table in one ALTER TABLE statement.

From MSDN\'s ALTER TABLE documenta

For MySQL (ver 5.6), you cannot do multiple column drop with one single drop-statement but rather multiple drop-statements:

mysql> alter table test2 drop column (c1,c2,c3);
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(c1,c2,c3)' at line 1
mysql> alter table test2 drop column c1,c2,c3;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'c2,c3' at line 1
mysql> alter table test2 drop column c1, drop column c2, drop c3;
Query OK, 0 rows affected (0.64 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> 

BTW, drop is shorthanded for drop column as you can see from drop c3 above.
