Comparing the CSV approach with the parameter approach below, which one do
you consider more maintainable and supportable?
Also consider the application will need one line per parameter used on the
stored procedure.
This which takes milliseconds to edit in Management Studio....
create proc getdata_dynamic
@csv varchar(max)
as
set @csv = replace( @csv, '''', '''''' )
exec( ' DECLARE @c int
select @c = count(*)
from somedata
where avalue in ( ' + @csv + ' )'
)
go
Or this which takes over two minutes to edit in Management Studio (on a 4GB
dual proc AMD machine)....

>>No; it would much more likely mean that he wants to pass a set of values
to his function. <<
Not very likely at all. Read the last 5+ years of postings here and
you will see that when they want to pass a list to an IN() predicate,
they explicitly ask about that. When they want to pass a table they
explicitly ask about that, as this guy did.
>> the ability to simply pass a set would make things enormously easier,
faster, and cleaner - which is probably why they're including it in SQL
2008. <<
Right now you can declare a huge number of parameters in a stored
procedure -- more than enough for any practical situation. But
programmers who grew up with BASIC and other interpreted languages
seem to panic at the the thought of a long parameter list.
>>I can think of several scenarios in which doing exactly what he is
asking would be necessary - reporting being the most obvious. <<
The most obvious is a system utility program which treats all tables
as tables rather than as part of a logical model. Now you are at the
meta data level, which has no place in an application or RDBMS
schema.
