-GENERAL 
-
-* implement remaining functions for CLSQL AODBC backend;
-* port Oracle backend to UFFI.
+TESTS TO ADD
+
+* CACHE-TABLE-QUERIES
+* Test that ":db-kind :key" adds an index for that key. This is complicated by different
+  backends showing autogenerated primary key in different ways.
+* Large object testing
+* Test bigint type
+* :db-constraint tests
+* test *db-auto-sync* 
+* test SELECT caching
+* for-each-row macro
+* universal-time 
 
 COMMONSQL SPEC
 
-* Missing: 
-
-  CACHE-TABLE-QUERIES 
-  *CACHE-TABLE-QUERIES-DEFAULT*
-  *DEFAULT-UPDATE-OBJECTS-MAX-LEN* 
-  UPDATE-OBJECT-JOINS

- >> Initialisation and connection 
-
-    INITIALIZE-DATABASE-TYPE
-     o should initialise appropriate backend 
-
-    STATUS 
-     o what is the behaviour in CommonSQL (esp :full parameter)? 
-
-
  >> The functional sql interface 
   
     SELECT 
       o keyword arg :refresh should function as advertised 
-      o should return (values result-list field-names)
-      o should coerce values returned as strings to appropriate lisp type
-
-    QUERY 
-      o should coerce values returned as strings to appropriate lisp type
-
-    LIST-ATTRIBUTE-TYPES
-      o should return list of (attribute datatype precision scale nullable)    
 
+ >> Symbolic SQL syntax 
 
- >> The object-oriented sql interface
+      o Complete sql expressions (see operations.lisp)
 
-    DEF-VIEW-CLASS
-      o get :target-slot working 
-      o implement :retrieval :immediate 
+         nvl (Oracle specific) 
+         userenv (Oracle specific) 
+        minus (Oracle specific: does the same as EXCEPT) 
 
-    DO-QUERY,MAP-QUERY,LOOP
-      o should work with object queries as well as functional ones 
+      o variables (e.g., table identifiers) should be instantiated at runtime 
 
 
- >> Symbolic SQL syntax 
+VARIANCES FROM COMMONSQL
 
-      o Complete sql expressions (see operations.lisp)
+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.

+OPTIMIZATIONS
+ 
+* Revisit result-type list creation,perhaps caching
 
-      o variables (e.g., table identifiers) should be instantiated at runtime 
+POSSIBLE EXTENSIONS
 
+* port Oracle backend to UFFI
+* large object support 
+* add support for prepared statements
