-- SQL State: 56023 Vendor Code: -512 Message: [SQL0512] Statement references objects in multiple databases. Cause . . . . . :   The statement refers to objects that reside on multiple databases.  The objects could be either explicitly qualified object names or alias names that are defined to reference a different database. This SQL statement can only refer to a single database. A CREATE TABLE AS that selects from a remote database cannot reference a table that has a FIELDPROC defined.  It cannot define a materialized query table. If the remote database is not on an IBM i server, the INCLUDING clauses are not allowed. Recovery  . . . :   Ensure all objects used in the statement reside at the same database.  Try the request again.
