Readme for psqlodbc.dll 4/15/98
-------------------------------------------------------------------------------
Latest binary and source updates available at http://www.insightdist.com/psqlodbc
I. Building the Driver from the source code
This section describes how to build the PostgreSQL ODBC Driver (psqlodbc.dll).
Microsoft Visual C++ version 4.0 or higher is required. There is no manually
constructed Makefile. The visual C++ environment automatically generates one
during the build process. Thus, the project binary files (".ncb", ".mdp", ".aps")
nor the makefile are really distributed as part of the source code release
(although they are probably in there anyway).
1. Create a new project workspace with the type DLL. For the name, type in the
name "psqlodbc".
2. The above step creates the directory "psqlodbc" under the
"\<Visual C++ top level directory>\projects" path to hold the source files.
(example, \msdev\projects\psqlodbc). Now, either unzip the source code release
into this directory or just copy all the files into this directory.
3. Insert all of the source files (*.c, *.h, *.rc, *.def) into the Visual project
using the "Insert files into project" command. You may have to do 2 inserts --
the first to get the 'c' and header files, and the second to get the def file.
Don't forget the .def file since it is an important part of the release.
You can even insert ".txt" files into the projects -- they will do nothing.
4. Add the "wsock32.lib" library to the end of the list of libraries for linking
using the Build settings menu.
5. Select the type of build on the toolbar (i.e., Release or Debug). This is
one of the useful features of the visual c++ environment in that you can
browse the entire project if you build the "Debug" release. For release
purposes however, select "Release" build.
6. Build the dll by selecting Build from the build menu.
7. When complete, the "psqlodbc.dll" file is under the "Release" subdirectory.
(i.e., "\msdev\projects\psqlodbc\release\psqlodbc.dll")
II. Using Large Objects for handling LongVarBinary (OLE Objects in Access)
Large objects are mapped to LONGVARBINARY in the driver to allow storing things like
OLE objects in Microsoft Access. Multiple SQLPutData and SQLGetData calls are usually
used to send and retrieve these objects. The driver creates a new large object and simply
inserts its 'identifier' into the respective table. However, since Postgres uses an 'Oid'
to identify a Large Object, it is necessary to create a new Postgres type to be able
to discriminate between an ordinary Oid and a Large Object Oid. Until this new type
becomes an official part of Postgres, it must be added into the desired database and
looked up for each connection. The type used in the driver is simply called "lo" and
here is the command used to create it:
create type lo (internallength=4,externallength=10,input=int4in,output=int4out,
default='',passedbyvalue);
Once this is done, simply use the new 'lo' type to define columns in that database. Note
that this must be done for each database you want to use large objects in with the driver.
When the driver sees an 'lo' type, it will handle it as LONGVARBINARY.
Another important note is that this new type is lacking in functionality. It will not
cleanup after itself on updates and deletes, thus leaving orphans around and using up
extra disk space. And currently, Postgres does not support the vacuuming of large
objects. Hopefully in the future, a real large object data type will be available.
But for now, it sure is fun to stick a Word document, Visio document, or avi of a dancing
baby into a database column, even if you will fill up your server's hard disk after a while!

/*
** SETUP.C - This is the ODBC sample driver code for
** setup.
**
** This code is furnished on an as-is basis as part of the ODBC SDK and is
** intended for example purposes only.
**
*/
/*--------------------------------------------------------------------------
setup.c -- Sample ODBC setup
This code demonstrates how to interact with the ODBC Installer. These
functions may be part of your ODBC driver or in a separate DLL.
The ODBC Installer allows a driver to control the management of
data sources by calling the ConfigDSN entry point in the appropriate
DLL. When called, ConfigDSN receives four parameters:
hwndParent ---- Handle of the parent window for any dialogs which
may need to be created. If this handle is NULL,
then no dialogs should be displayed (that is, the
request should be processed silently).
fRequest ------ Flag indicating the type of request (add, configure
(edit), or remove).
lpszDriver ---- Far pointer to a null-terminated string containing
the name of your driver. This is the same string you
supply in the ODBC.INF file as your section header
and which ODBC Setup displays to the user in lieu
of the actual driver filename. This string needs to
be passed back to the ODBC Installer when adding a
new data source name.
lpszAttributes- Far pointer to a list of null-terminated attribute
keywords. This list is similar to the list passed
to SQLDriverConnect, except that each key-value
pair is separated by a null-byte rather than a
semicolon. The entire list is then terminated with
a null-byte (that is, two consecutive null-bytes
mark the end of the list). The keywords accepted
should be those for SQLDriverConnect which are
applicable, any new keywords you define for ODBC.INI,
and any additional keywords you decide to document.
ConfigDSN should return TRUE if the requested operation succeeds and
FALSE otherwise. The complete prototype for ConfigDSN is:
BOOL FAR PASCAL ConfigDSN(HWND hwndParent,
WORD fRequest,
LPSTR lpszDriver,
LPCSTR lpszAttributes)
Your setup code should not write to ODBC.INI directly to add or remove
data source names. Instead, link with ODBCINST.LIB (the ODBC Installer
library) and call SQLWriteDSNToIni and SQLRemoveDSNFromIni.
Use SQLWriteDSNToIni to add data source names. If the data source name
already exists, SQLWriteDSNToIni will delete it (removing all of its
associated keys) and rewrite it. SQLRemoveDSNToIni removes a data
source name and all of its associated keys.
For NT compatibility, the driver code should not use the
Get/WritePrivateProfileString windows functions for ODBC.INI, but instead,
use SQLGet/SQLWritePrivateProfileString functions that are macros (16 bit) or
calls to the odbcinst.dll (32 bit).
