How can I correct this error: Data source name not found and no default driver specified

Question

I have a website that runs in Windows server, and it works perfectly fine. I tried to make a copy in my localhost but I get the error:

Warning: odbc_connect() [         


        

Answer 1

It's likely the shortcut for setting ODBC data sources is pointing to the 32bit data sources instead of 64bit.

Go to control panel -> administrative tools --> select data sources(ODBC) --> then right click on that file --> go to properties --> in the shortcut tab -> change the path from

%windir%\System32\odbcad32.exe

to

%windir%\SysWOW64\odbcad32.exe

and make your connection. the driver for MS Access will work fine now.

If it doesnt work, try to connect to the ODBC with a sentence like this:

$conn = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=C:\YourFolder\YourFile.mdb",'Youruser', 'YourPassword');

The last 2 leave then just the the '' if you dont have any user or password

Answer 2

I was getting the same error on PHP 7.0.8 64bit while trying to connect to an Access .mdb.

I had to do two things:

1. Install the 64bit version of "Microsoft Access Database Engine 2010 Redistributable" (even with Access 2016 installed I was getting your error). You can download the driver from:

   https://www.microsoft.com/en-us/download/details.aspx?id=13255

   Then, if you go to the ODBC Data Source Administrator, you should notice the 64bit version.

2. Change the driver string to:

   Driver={Microsoft Access Driver (*.mdb, *.accdb)}

Hope it helps other people.
