 * Incompatible 
 
  >> The functional sql interface 
   
     SELECT 
       o keyword arg :refresh should function as advertised 
-      o should accept type-modified database identifiers (e.g., 
-        [foo :string] which means that the values in column foo are returned 
-        as Lisp strings) 
 
- >> The object-oriented sql interface
+ >> Symbolic SQL syntax 
 
-    DEF-VIEW-CLASS
-      o get :target-slot working 
-      o implement :retrieval :immediate 
+      o userenv (Oracle specific but deprecated in Oracle 9) 
 
-    LOOP
-      o should work with object queries as well as functional ones 
+VARIANCES FROM COMMONSQL
 
- >> Symbolic SQL syntax 
+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.
 
-      o Complete sql expressions (see operations.lisp)
+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.
