+This is the header of the cadabra source file.
+
+;;;; a CMUCL/OCI implementation of a subset of the DBI interface
+;;;;
+;;;; The original version of this code was copyright (c) 1999-2000 Cadabra Inc.
+;;;; It was placed in the public domain by Cadabra in January 2000.
+;;;;
+;;;; The implementors of the original version were Winton Davies
+;;;; <wdavies@cadabra.com> and William Newman <william.newman@airmail.net>.
+;;;; The code will be maintained by Winton Davies.
+
+;;;; known issues:
+;;;; * The code will leak C resources if errors occur in the the wrong
+;;;; places, since it doesn't wrap its allocation/deallocation
+;;;; logic in the necessary EVAL-WHENs to prevent this. (This could be
+;;;; easily be an issue for long-running processes which recover from
+;;;; database errors instead of simply terminating when they occur. It's
+;;;; not an issue for programs which consider database errors so abnormal
+;;;; that they die immediately when they encounter one.)
+;;;; * Instead of reading Oracle header files automatically, this code
+;;;; uses constants, types, and function signatures manually transcribed
+;;;; from the Oracle header files. Thus, changes in the header files
+;;;; may require manual maintenance of the code. (This version was written
+;;;; for Oracle 8.1.5.)

+;; the hairy part of MAKE-QUERY-CURSOR: Ask OCI for information
+;; about table columns, translate the information into a Lisp
+;; vector of column descriptors, and return it.
+
+;; Allegro defines several flavors of type conversion, but this
+;; implementation only supports the :AUTO flavor.
+
+;; A note of explanation: OCI's internal number format uses 21
+;; bytes (42 decimal digits). 2 separate (?) one-byte fields,
+;; scale and precision, are used to deduce the nature of these
+;; 21 bytes. See pp. 3-10, 3-26, and 6-13 of OCI documentation
+;; for more details.
+
+;; When calling OCI C code to handle the conversion, we have
+;; only two numeric types available to pass the return value:
+;; double-float and signed-long. It would be possible to
+;; bypass the OCI conversion functions and write Lisp code
+;; which reads the 21-byte field directly and decodes
+;; it. However this is left as an exercise for the reader. :-)
+
+;; The following table describes the mapping, based on the implicit
+;; assumption that C's "signed long" type is a 32-bit integer.
+;;
+;; Internal Values SQL Type C Return Type
+;; =============== ======== =============
+;; Precision > 0 SCALE = -127 FLOAT --> double-float
+;; Precision > 0 && <=9 SCALE = 0 INTEGER --> signed-long
+;; Precision = 0 || > 9 SCALE = 0 BIG INTEGER --> double-float
+;; Precision > 0 SCALE > 0 DECIMAL --> double-float
+
+;; (OCI uses 1-based indexing here.)
+
+;; KLUDGE: This should work for all other data types except those
+;; which don't actually fit in their fixed-width field (BLOBs and the
+;; like). As Winton says, we (Cadabra) don't need to worry much about
+;; those, since we can't reason with them, so we don't use them. But
+;; for a more general application it'd be good to have a more
+;; selective and rigorously correct test here for whether we can
+;; actually handle the given DEREF-DTYPE value. -- WHN 20000106
+
+;; Note: The OCI documentation doesn't seem to say whether the COLNAME
+;; value returned here is a newly-allocated copy which we're
+;; responsible for freeing, or a pointer into some system copy which
+;; will be freed when the system itself is shut down. But judging
+;; from the way that the result is used in the cdemodsa.c example
+;; program, it looks like the latter: we should make our own copy of
+;; the value, but not try to free it.
+
+;; WORKAROUND: OCI seems to return ub2 values for the
+;; +oci-attr-data-size+ attribute even though its documentation claims
+;; that it returns a ub4, and even though the associated "sizep" value
+;; is 4, not 2. In order to make the code here work reliably, without
+;; having to patch it later if OCI is ever fixed to match its
+;; documentation, we pre-zero COLSIZE before making the call into OCI.
+
+;; To exercise the weird OCI behavior (thereby blowing up the code
+;; below, beware!) try setting this value into COLSIZE, calling OCI,
+;; then looking at the value in COLSIZE. (setf colsize #x12345678)
