Creating a stored proc that references an optional column

Is it possible to create a stored proc which references a non-existent
field without getting the "invalid column name" error?
The field will only exist in one or two production databases (not in
all) but we still want the stored proc to exist in all databases so
that users in the future may add the new field to their own database
(using a Dictionary builder form that exists in the application) and
then be able to run the report (via the stored procedure) that
references the field.
The stored proc checks that the field exists before proceeding.
ThanksIt is possible only if the table does not exist when the procedure is
created. However, this is not a good idea. It would be better to create
two different procedures.

Creating a Connection to Database that Does Not Yet Exist

Hello All!
I am in the process of developing a DTS package. My
package will behave as follows:
1. Backup my live database.
2. Using the backup from Step 1., the backup will be
restored using a DIFFERENT name (NewDatabase).
3. Manipulate NewDatabase database.
How can I create a connection in my DTS Package when, at
the time I am creating the package, the NewDatabase
database does not exist? Do I have to use Disconnected
Edits? If so, how? Or, do I use Microsoft Data Link?
If so, how? Or, do I use something else. (As you can
tell from my questions, I am not an expert at this :-)
Any suggestions are greatly appreciated!!You should be able to connect to the master database to do what you need to
do initially.

the one to the original database. However, I need my DTS
package to create a connection to the NewDatabase
database once the task of restoring with a new name is
complete.
Thanks in advance!

set it to connect to master, then create a dynamic task properties and a
global variable <dbname> to change the value of catalog property in
Disconnect Edit DE at run time.
then when you execute the dts package need to execute with the /A switch to
pass the <db> variable which u proide at run time see example below
dtsrun /S <servername> /E /N<packagename> /A <db>:8=newdatabase
this way u can connect to a database at runtime.
