SQL Server equivalent to Oracle LEAST?

Question

I\'ve been looking for a good equivalent to the Oracle LEAST function.

I\'m hoping to implement a user defined function that does about 10 fairly complex calculation

Answer 1

mayby this query could help:

 SELECT  min(c1)  
 from ( 
      select expression1 as c1  
      union all
      select expression2 as c1 
      union all 
      select expression3 as c1
 )

Answer 2

The function Least() is applied horizontally in Oracle (on a row level), while Min() is applied vertically over a column. The example in the question required Min().
