XML Bulk Load: call

Moved a database over to a new SQL server. That database had a couple
of stored procedures that call two different databases. I linked the
servers, but I know that the tables that show up correspond to the
default database on the security account i have setup to connect to the
server. Is there any way to allow connections to other databases/tables
with the same link?
You can connect to more than just what you see - just use
the four part name qualifier of:
LinkedServerName.Database.Owner.Object
That's controlled by permissions, not by what you "see" in
Enterprise Manager listed as the tables for the linked
server. The tables displayed are based on what the default
database for the login is if you have not specified a
Catalog (database) for the linked server property. If you
want to change the database you are initially connected to,
enter the database name in the Catalog property for the
linked server.

I need a scalar function that I can call from a select statement (with other
criteria) that will dynamically return all the columns (And sometimes their
datatypes with a mode option), from a table or view from any database on tha
t
server. The function needs to work in both SQL 2000 and SQL 2005. I have
listed the function I have tried to create below (using the master database
trying to make a system object but 2005 will not allow me to update system
tables with the UID of 4 - sys in 2005 and system_schema_function in
2000...yes I already know I am a bad developer for trying to cheat). Any
help on this would be greatly appreciated!
Please excuse the formating in advance (was created in VS sql 2005).
Thank You
Jared

First: I really appreciate the feedback
Second: I understand that you cannot execute statements in UDF's which is
why I am looking for help. A sp will not help me in this situation because
I
need the information within another dynamic statement, and you cannot call a
n
sp within inline SQL. I could use the code that makes this UDF and place it
in every instance I need within the sp I call but we are talking about 87
diffrent calls to date and more coming around the corner. I would really
like to find a solution that will allow me to somehow do the following by
making a system function or I will need to start making an xp that can be
called from a UDF (Of cource that calls for me to register the xp and have
code outside of T-SQL that makes things harder to manage).

There is a way: you can call extended stored procedures from UDFs. Thus
you can call xp_cmdshell which in it's turns invokes to OSQL and
runs the query. The query would have to insert the data into a table,
and then you would pick up the data from the table in the UDF.
Now, the design of UDFs is that they are not supposed to change database
state, which is why all those restrictions with them are there. This is
a loophole, and there is not really any guarantees that it will work
as expected - if you get something work now, it could break SQL 2005
or in the next service pack.
Thus, I strongly discourage you from trying this. It's a fun thing to
do at parties, but is unsuitable for production code.
What you really should do is to go back to your original business
problem and analyse why you ended up with all these 87 calls. The best
I can recommend at this point is to bounce data over a temp table, or
a process-keyed table, see http://www.sommarskog.se/share_data.html
for details. But I suspect that you need a complete redesign.

a Storedprocedure as a source of a result set, but this has many
mantrap and is not suggestable.
HTH, Jens Suessmeyer.|||Thank you everyone that replied to this post. The solution is actually
simplified (I was trying to make it way to hard). I hold a master schema
table of all the user databases that are will be using dynamic table/view
creates and dynamic insert/update/delete. So my original code/function that
is not dynamic (listed below) works great but only in the database that the
original objects reside...so the solution is to use OSQL and have a system
wrapper that compiles the same function in every database that is flagged,
that way the dynamic procedure that is already in whatever database that is
flagged will have access to return the results I need. Kinda of a kluge to
have multiple objects with diffrent id's in each database, but it works.
