-GENERAL 
+TESTS TO ADD
 
-* test on mcl. SCL no longer affordable to individuals;
-* implement remaining functions for CLSQL AODBC backend;
-* port Oracle backend to UFFI.
+* 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.
+* Test bigint type
+* :db-constraint tests
+* test *db-auto-sync* 
+* for-each-row macro
+* universal-time 
+* owner phrases for postgresql and oracle backends
+* test of large table with large numbers of rows, greater than 2x the number of
+  rows (200) returned by the oracle backend at a time
+* Number and Char field types
 
-COMMONSQL SPEC
+COMMONSQL INCOMPATIBILITY
 
-* Missing: 
+   o userenv (Oracle specific but deprecated in Oracle 9) 
+ 
+VARIANCES FROM COMMONSQL
 
-  CACHE-TABLE-QUERIES 
-  *CACHE-TABLE-QUERIES-DEFAULT*
-  *DEFAULT-UPDATE-OBJECTS-MAX-LEN* 
-  UPDATE-OBJECT-JOINS 
-  INSTANCE-REFRESHED
+CLSQL starts with in transaction AUTOCOMMIT mode. To begin a transaction,
+START-TRANSACTION has to be called.
 
+OPTIMIZATIONS
+ 
+* Revisit result-type list creation, perhaps caching
 
-* Incompatible 
+POSSIBLE EXTENSIONS
 
+* extend large object support to databases beyond postgresql, improve large object api
+* add support for prepared statements
+* port Oracle backend to UFFI
 
- >> 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 should accept keyword arg :refresh and call INSTANCE-REFRESHED
-      o should return (values result-list field-names)
-      o should coerce values returned as strings to appropriate lisp type
-
-    QUERY 
-      o should return (values result-list field-names) 
-      o should coerce values returned as strings to appropriate lisp type
-
-    LIST-ATTRIBUTE-TYPES
-      o should return list of (attribute datatype precision scale nullable)    
-
-
- >> The object-oriented sql interface
-
-    DEF-VIEW-CLASS
-      o get :target-slot working 
-      o implement :retrieval :immediate 
-
-    DO-QUERY,MAP-QUERY,LOOP
-      o should work with object queries as well as functional ones 
-
-
- >> Symbolic SQL syntax 
-
-      o Complete sql expressions (see operations.lisp)
-
-         substr
-         some 
-         order-by 
-         times 
-         nvl
-         null 
-         distinct
-         except 
-         intersect 
-         between
-         userenv
-
-      o variables (e.g., table identifiers) should be instantiated at runtime

-NOTES ABOUT THE BACKENDS

-MYSQL 
-
-drop-index:   requires a table to be specified with the :from keyword parameter
-transactions: don't seem to work  
-views:        mysql does not support views  
-queries:      nested subqueries do not seem to work 
-
-SQLITE 
-
-create-view: column-list parameter not supported
