Subj:   The ORDER BY clause
 
From:   Narayan Murthy

Given you had 4 columns in a table say "T1" and given a query

SELECT * FROM T1 order by 1,2,3,4;


Can the above query contain the following values in the ORDER BY clause

a. null

b. <= 0

c. > 4

d. repeating column specification i.e. ORDER BY 1,2,1


Case a. & d. give no error currently, but do they make sense, if so what.

Case b. & c. give error (this is correct - isn't it)


Narayan
