Unix port of psqlodbc, brought to you by:
Gerald Gryschuk(ggryschuk@home.com)
This is the first release of a port of psqlodbc to Unix(specifically Linux),
as such the installation may not be as straight forward as it could be(then
again it might be). As well the only testing of the driver has been with
the real project I'm working on, since it seems to be working there I assumed
it was ready to go out. This port works with Ke Jin's iodbc driver manager
although there is no theoretical reason why it couldn't work with other
driver managers for UNIX(I know of none though). The FreeODBC site
(http://users.ids.net/~bjepson/freeODBC/) has a link to download the current
version of iodbc(iodbc-2.12).
This driver has been successfully compiled and tested on a RedHat 4.1 system
using both gcc 2.7.2 and egcs 1.0.2.
INSTALLATION:
If you have a system any where close to mine this will be easy, just
copy Makefile.lnx to Makefile then type 'make' and see what happens. Note
that if you have not enabled logging(read the file misc.h) then you
may get alot of warning messages, just ignore these, they shouldn't be
a problem. If this doesn't work, well... I don't know what to say, see if
you can figure out what's wrong,fix it and send me a message. If everything
makes o.k. you can 'make install' which will install the shared library
(in /usr/local/lib) and a WINDOWS type INI file in /etc (called odbcinst.ini,
see CONFIGURATION below). If you want to program using this driver do a
'make install-headers' which will install programming header files in
/usr/local/include/iodbc. If you don't like these install locations edit
Config.mk and change the environment variable DESTDIR(and possible DESTINCDIR
to get rid of the /iodbc) to suit your system.
CONFIGURATION:
The psqlodbc driver reads two Windows type INI files for configuration,
one called odbcinst.ini located in /etc which is used for system wide
configuration of the driver and one in the users home directory called
.odbc.ini, which can be used to override the system wide settings. Note that
the location of odbcinst is currently hardcoded into the source so if you
want to change this you have to change it in the source as well. This latter
file is also searched for by iodbc and is where
the DataSource definitions are placed. The format of both files is exactly
like that of a Windows INI file using key,value pairs. A DataSource definition
is started with a section name enclosed in square brackets i.e. [PostODBC].
Comments are started using a ';' character and are restricted to being
only on seperate lines(i.e. no comments are allowed on definition lines).
The important keywords for psqlodbc are:
Driver = (location where the psqlodbc library was installed)
ex. Driver = /usr/local/lib/libpspqlodbc.so
ServerName = hostname or ip-address of postgreSQL server
ex. ServerName = simpsons.springfield.com
or ServerName = 192.1.1.1
Database = name of database to connect to
ex. Database = template1
Port = tcp port that the postgreSQL server is listening on, note
that this need not be set as the driver defaults to the
default postgreSQL port of 5432. Of course if your server
is listening on a different port than you need to say
what it is here.
Username = name of authorized postgreSQL user
ex. Username = homer
Password = the password for the user named in Username. Note
that if you have password checking on in postgreSQL
you have to have this field. Unfortunately this means
storing clear text passwords in a file. If this bothers
you, well... write a dialog box routine and send it
to me.
ex. Password = Doh!
ReadOnly = 0 or 1. Default is 1 => database IS readonly. If
set to 0, database is read-write.
ex. ReadOnly = 0
Protocol = 6.2 to force the use of Postgres 6.2 protocol
The odbcinst.ini file is where sytem wide settings are kept. There are
quite a number of these, all of which have built-in defaults. Since I'm
not even sure what they are all for I won't try to describe them, check
the file dlg_specific.h for a list and some explanation. Two that I found
useful are Debug and CommLog, which can be used to tailor logging of messages
by the driver(note that you have to have defined MY_LOG and Q_LOG during
compilation of the driver, see the file misc.h for an explanation). If
you have logging On(ie. CommLog = 1 and/or Debug = 1) then logging will
occur to the files /tmp/mylog.log(Debug, only developers will be
interested) and /tmp/psqlodbc.log(end user log file).
USE:
run an ODBC enabled application :-) .
O.k. Well, the only ODBC compliant applications that I can
"guarantee" to work are those that are compiled using the following
headers that come with this driver, iodbc.h, isql.h and isqlext.h.
BUGS,etc.
If you have problems with compiling/installing or making this
package send e-mail to me at:
gerald.gryschuk@home.com or to the pgsql-interfaces mailing list
pgsql-interfaces@postgresql.org .
Ports to different Unices are greatly appreciated and can probably be
sent to me for now(although this may change shortly).
Bugs of a general nature should still be sent to the current
maintainer or to the interfaces list.

/* Module: parse.c
*
* Description: This module contains routines related to parsing SQL statements.
* This can be useful for two reasons:
*
* 1. So the query does not actually have to be executed to return data about it
*
* 2. To be able to return information about precision, nullability, aliases, etc.
* in the functions SQLDescribeCol and SQLColAttributes. Currently, Postgres
* doesn't return any information about these things in a query.
*
* Classes: none
*
* API functions: none
