SQL state S1090: Almost connected to mysql via PHP/odbc

Hello, thanks to the precious suggestions I had on this list some day ago, I have made some progresses, or at least have something new to report. I would like to ask now above the error mentioned in the subject, because I have not found it inside www.,mysql.com I have a database called m97. It *is* listed when I run "show databases" in themysql monitor. It *shows* when I run isql -v m97. I have modified /etc/odbc.ini and /etc/odbcinst.ini and /etc/odbc.ini as follows: /etc/odbc.ini [m97] Trace = On TraceFile= stderr Driver = /usr/lib/libmyodbc.so DSN = m97 SERVER = localhost USER = test PASSWORD = gee PORT = 3306 OPTIONS = 1 DATABASE= m97 SOCKET = /tmp/mysql.sock ############################################# /etc/odbcinst.ini # From the MyODBC package [MySQL] Description = ODBC for MySQL Driver = /usr/lib/libmyodbc.so FileUsage = 1 In the PHP file I have: putenv("LD_LIBRARY_PATH=/usr/lib/"); putenv("ODBCINSTINI=/etc/odbcinst.ini"); putenv("ODBCINI=/etc/odbc.ini"); $DSN="m97"; $cnx = odbc_connect( $DSN , 'test', 'gee' ); The result in netscape is still: Warning: SQL error: [unixODBC][TCX][MyODBC]Invalid DSN specified, SQL state S1090 in SQLConnect in /home/mweb/public_html/test.php on line 360
