+UPDATE-OBJECT-JOINS:
+ Rather than simply reading the values for each
+ object, to meet CommonSQL spec need to generate a single
+ query to read values for all objects, up to max-len count.
+
+COMMIT,ROLLBACK,START-TRANSACTION: 
+ When COMMIT or ROLLBACK are called outside of WITH-TRANSACTION, an sql 
+ transaction must be explicitly started first with START-TRANSACTION.

+OPTIMIZATIONS

 * Revisit result-type list creation,perhaps caching
-* Use an inner join for :target-slot in SELECTS rather than multiple
-  queries. For example, in the test suite:
-    SELECT address.addressid,address.street_number,... FROM address
-      INNER JOIN employee_address ON employe_address.address_id=address.address_id
-      AND emplid=<id>
