		-- alter table testc add num3 money null

		-- drop table testc 

		

		declare @i int

		select @i = 1

		

		while @i < 100

		begin

		insert into testc (num1, num2, num3) values (rand() * 10000, rand(), rand() * 100000)

		select @i = @i + 1

		end

		

		-- create index myindex_testc on testc (row_id)

		-- select count(*) from testc
