When a coordinator of a sharded DBMS receives from a client a query that has an XML operator that references a column in a sharded table and returns an XML image having an XML image type, then the coordinator issues a remote query that uses a new operator to ensure that the shard returns a TBX BLOB having a TBX type. In response to receiving the remote query with the new operator, each shard extracts a binary large object (BLOB) out of the XML image at the shard and returns the TBX BLOB data to the coordinator. In addition, the sharded DBMS provides a make-XML operator that the coordinator uses to work with the TBX BLOB received from each shard and recreate an XML type image, which is the result that the client expects.
