Take a look at this code, will the select return anything or not? Look at the subquery and notice that there is no FROM there.
CREATE TABLE TestQuery (TestID int)
SELECT * FROM information_schema.columns
WHERE column_name =( SELECT column_name
WHERE column_name = 'TestID')

About Denis Gobo
I was born in Croatia in 1970, when I was one I moved to Amsterdam (and yes Ajax is THE team in Holland) and finally in 1993 I came to the US. I have lived in New York City for a bunch of years and currently live in Princeton, New Jersey with my wife and 3 kids. I work for Dow Jones as a Database architect in the indexes department, one drawback: since our data goes back all the way to May 1896 I cannot use smalldates ;-( I have been working with SQL server since version 6.5 and compared to all the other bloggers here I am a n00b. Some of you might know me from http://sqlservercode.blogspot.com/ or even from some of the newsgroups where I go by the name Denis the SQL Menace If you are a Tek-Tips user then you might know me by the name SQLDenis, I am one of the guys answering SQL Questions in the SQL Programming forum.
