Things i wish SQL supported. The lazy man's list.

Question

Things i wish SQL supported. This is the lazy man's list. Just to make things easier.
1) IT - refer to the first COLUMN in the SELECT clause.
- SELECT Name FROM Item WHERE IT is LIKE 'ABC%';
2) THEY - refer to each COLUMN in the SELECT list, individually.
- SELECT Name, Type FROM Item WHERE THEY ARE NOT NULL;
3) PK - refer to the PRIMARY KEY of the TABLE.
- SELECT * FROM Item WHERE PK = 12345;
Number 1 is what i'd like best.

Answer 1

"> Number 1 is what i'd like best.
That one is (arguably) the least useful. Just typing "IT" vs. the actual column name?"
Yep. For ad-hoc queries, it would save quite a bit of time.
3) is dangerous because constraints can be altered (granted, PK is less likely). And
then when I debug a sql statement like this, Firstly, i would not want this in production code. Just like i'd never use * in production code (outside of COUNT and EXISTS).
Secondly, the PK is not just a constraint, it defines the entire TABLE. Indeed, a FOREIGN KEYs default REFERENCING refers to the PK. So, this isn't something unheard of.
I would have to refer to the constraints to >see what column(s) are being used. Yuck.You run queries on TABLEs where you donlt know which COLUMN is the PRIMARY KEY? Shame on you! :)
2) I can't imagine ever using this one. I don't remember ever selecting a dozen columns
followed by a dozen and...is not null conditions.I have. But even if it's not for NULL, there are times where i want to check things like UPPER, or the like. Similarly, using them for IN, like WHERE THEY are IN (SELECT * FROM some_other_TABLE) or the like.
Just a thought. I appreciate your comments.
