Using COALESCE function in MSSQL (cleaner code) (Score 1)

Instead of this:

create procedure myTestProc @someDateTime datetime = '1/1/2050' as
--put insert, delete, update here....
select * from someTable
where (@someDateTime >= someTable.someDate or @someDateTime = '1/1/2050')

Try COALESCE, it is cleaner, and you don't need to worry what happens if your code is still in use 44 years from now.

create procedure myTestProc @someDateTime datetime = NULL as
--put insert, delete, update here....
select * from someTable
where (@someDateTime >= COALESCE(@someDateTime, someTable.someDate)
