13// setup: set PDOTEST_DSN environment variable
14//        for MyODBC (MySQL) and MS SQL Server, you need to also set PDOTEST_USER and PDOTEST_PASS
15//
16// can use MS SQL Server on Linux - using unixODBC
17//   -RHEL6.2
18//   -download & instructions: http://www.microsoft.com/en-us/download/details.aspx?id=28160
19//      -Linux6\sqlncli-11.0.1790.0.tar.gz (it calls RHEL6.x 'Linux6' for some reason)
20//   -follow instructions on web page and install script
21//   -may have to specify connection info in connection string without using a DSN (DSN-less connection)
22//      -for example:
23//            set PDOTEST_DSN='odbc:Driver=SQL Server Native Client 11.0;Server=10.200.51.179;Database=testdb'
24//            set PDOTEST_USER=sa
25//            set PDOTEST_PASS=Password01
26//
27// on Windows, the easy way to do this:
28// 1. install MS Access (part of MS Office) and include ODBC (Development tools feature)
29//       install the x86 build of the Drivers. You might not be able to load the x64 drivers.
30// 2. in Control Panel, search for ODBC and open "Setup data sources (ODBC)"
31// 3. click on System DSN tab
32// 4. click Add and choose "Microsoft Access Driver (*.mdb, *.accdb)" driver
33// 5. enter a DSN, ex: accdb12
34// 6. click 'Create' and select a file to save the database as
35//       -otherwise, you'll have to open MS Access, create a database, then load that file in this Window to map it to a DSN
36// 7. set the environment variable PDOTEST_DSN="odbc:<system dsn from step 5>" ex: SET PDOTEST_DSN=odbc:accdb12
37//         -note: on Windows, " is included in environment variable
38//
39// easy way to compile:
40// configure --disable-all --enable-cli --enable-zts --enable-pdo --with-pdo-odbc --enable-debug
41// configure --disable-all --enable-cli --enable-pdo --with-pdo-odbc=unixODBC,/usr,/usr --with-unixODBC=/usr --enable-debug
