hi Jon

of course, a workaround with
exec "dynamic script"
or PUTTING conditions into a single SELECT

CREATE	PROCEDURE dbo.test1
	@choice bit = 0
as
	SELECT CASE WHEN @choice=0 THEN 1 ELSE 0 END x INTO #TEMPTABLE

is possible;
but:
* Exec 'SELECT ....'
- is unreadable
- is uncacheable

* conditional select
- can become unreadable
- it can easy confuse the MS SQL optimizer
and create of the inefficient plans

MS SQL it is a good product,
but in some points the team has been overwhelmed from the complexity
