Bill,

Not sure about the refcursor thningy you mentioned.

I think I would do it another way.

Always have a db link available at compile time for your package. The link may simply point back to a user in the same database. The thing to do is to make sure a dblink exists, and that it currently is valid. Remember, a db link is simply another Oracle object. All that is required is to have one in place for the compile to work.

At run time, you can drop and re-create the link, pointing to wherever it needs to point to.

Hope this helps.

Hi,

I'm trying to incorporate a procedure in a package that needs to run using a dblink name supplied at runtime. The dblink is used in the dml inside the procedure, but when I compile the package I get "ORA-00942 table or view does not exist" for all the sql referencing the dblink.

Here is a code snippet:

PROCEDURE CREATE_WC_OVER_DBLINK (     
	DBLINK VARCHAR2)

v_dblink VARCHAR2(100) := dblink;

BEGIN INSERT INTO mm_product_temp (rec, rec_old, name, is_disabled, is_workingcopy)
(SELECT mm_product_seq.nextval, rec, name, is_disabled, is_workingcopy FROM mm_product_at_v_dblink
WHERE last_update IS null);

.....

END;
/

The ORA-00942 shows up for the line with the INSERT statement.

Looking for ideas as to how to do this. I saw a MetaLink forum posting indicating that the way to do this is to create a refcursor, then use a function to return the supplied sql to the refcursor, then open the refcursor, etc. etc.

Is this the only way to do it?

thanks

bill
