问题

I'm trying to import data from a MySQL Database to an Excel 365 (32 bit) Workbook.

This is a DB I can link to without any issues :

This is the DB I can't link to :

I've downloaded the following connector : MySQL Connector Net 6.10.6

I suspect that this is not the correct connector for the second DB. The error is this :

[MySQL: Unable to connect to any of the specified MySQL hosts.]

Could someone point me to the beginning of a solution ?

I've also tried to connect via VBA but I also get an error which must be due to the same causes as above.

回答1:

If the database server and the database client (Excel) are running on different machines then they cannot communicate via UNIX filesystem sockets.

If you specify localhost as the target host in a libmysql client, then the client will try to connect via the (Unix) filesystem socket.

On the other hand, if you instead specify 127.0.0.1, it will use a TCP socket.

EDIT:

In response to your comment, the target host would be specified in the location specified on this page, or it can also be installed via command line with these steps.

Setting up a MySQL ODBC DSN on Windows 7 64-bit:

I have a faint recollection of the last time I setup an ODBC DSN to MySQL.

It was a while ago so I might be mistaken on the details but I'm pretty sure that the only was I was able to get it working on a 64-bit system (possibly because the server was 32-bit?) was to install both the 32-bit and 64-bit drivers (from here) into separate folders, rebooting between each install. As I recall, it took a dozen install/uninstalls before I got it right.

Once it was properly installed, I had to administer it with Window's 32-bit version of ODBC Administrator.

There's 2 versions of ODBC Administrator (aka 'Data Sources'), confusingly:

My 64-bit version is located at : c:\windows\system32\odbcad32.exe
My 32-bit version is located at : c:\windows\SysWOW64\odbcad32.exe

_{Note that much of this is from memory and unverified!}

I have this text file sitting in my "mySQL Notes" folder, so I gather I ended up using the command line to get it installed:

myodbc-installer -s -a -c1 -n " mysqlDSN " -t "DRIVER=MySQL ODBC 5.3 Unicode Driver;SERVER= (server name) ;DATABASE= (database name) ;UID= (user name) ;PWD= (password) "

In my case I was setting up connection to a web host server, so I referred to my CPanel for the server / database / uid values.

...and as I recall, I had to run it from the location of the 32-but version of the myodbc-installer. Also, you'll have an ODBC.INI text file somewhere showing the configuration.
