All I got is this message: Warning: SQL error: [Microsoft][ODBC Microsoft Access Driver] '(unknown)' is not a valid path.

No, just testing some options, we found out that it went from very slow (getting 100 records lasts 1 till 10 seconds) to fast access (almost same speed as with using JDBC from Servlets) to 0.2 till 0.3 seconds.

We simply added the optional parameter Cursortype to odbc_connect, and with the cursortype SQL_CUR_USE_ODBC it changed in that way!

You cannot make a system DSN with a UNC (\Server\resource), so you must map the drive Cute isn't it? I quit on ODBC and went via ADO, this is the code that works:=== CODE ===$db = '\\server\resource\db.mdb';$conn = new COM('ADODB.

Connection');$conn-Open("DRIVER=; DBQ=$db");// Driver do Microsoft Access (*.mdb)// must be the name in your odbc drivers, the one you get// from the Data Sources (ODBC).// In this case, I'm in Mexico but the driver name is in portuguese, thanks Microsoft.$sql = 'SELECT username FROM tbl Usuarios';$res = $conn- [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified If you keep running into this on the 64 bit versions of windows, ie server 2008, and none of the other solutions helped.
