I have a table with 2000 record.
I want to insert a row below the first row in my table. Is it possible?
So I'm just starting to learn about query processing and such in databases and I'm having some trouble. I don't really understand how to compute the minimum number of block reads given a relation and a query I guess you could say. If anyone could help me out, it'd be much appreciated. Here is ...

CREATE TABLE [dbo].[foo](
[foo_id] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[val1_id] [int] NULL,

[val2_id] [int] NULL,
[val2_amount] [int] NULL,
[val3_id] [int] NULL,
[val3_amo...

I can't seem to figure out why sqlsrv_fetch_assoc only returns 1 row when there are 2 rows in the result set according to sqlsrv_num_rows. I've tried to hard code the parameter, but I still get the same result.

The uncanny valley is a hypothesis in the field of robotics and 3D computer animation, which holds that when human replicas look and act almost, but not perfectly, like actual human beings, it causes a response of among human observers. The "valley" refers to the dip in a graph of the comfort level of humans as a function of a robot's human likeness.
The term was coined by the robotics professor Masahiro Mori as Bukimi no Tani Genshō (不気味の谷現象) in 1970. The hypothesis has been linked to Ernst Jentsch's concept of the "uncanny" identified in a 1906 essay, "On the Psychology of t...
