Dynamic connection string

I need to have a dynamic connection string:

One is for my local machine, on which I do the coding and testing

and second is for the web server on which I deploy the code.

Since I'm using MySQL, the string is different - for example the server.
I thought on using something like:
sqlDriver="DRIVER={MySQL ODBC 3.51 Driver};"

hostID=request.ServerVariables("LOCAL_ADDR")

if (hostID="127.0.0.1") then

sqlSERVER="SERVER=myServer;"

sqlDB="DATABASE=myDB;"

UID="USER=myUser;"

PWD="PASSWORD=myPass;"

else

sqlSERVER="SERVER=my2Server;Port=serverPort;"

sqlDB="DATABASE=serverDB;"

UID="USER=serverUser;"

PWD="PASSWORD=serverPass;"

end if
Any idea on how to implement something similar?
