![]() For details about the parameters that can be set for each DSN, see ODBC Configuration and Connection Parameters. Parameters are specified in the form of =.

If you are creating the first DSNįor the driver, you must manually create the odbc.ini file and add the entry to the file.ĭSN name and driver name (Snowflake), in the form of =. If a user or system DSN has already been created for the driver, add the new entry to the odbc.ini file that already exists in the corresponding directory for the type of DSN you are creating. At the same time, it is worth noting that multiple ODBC driver vendors (including my own employer, OpenLink Software) offer ODBC Drivers for SQL Server that are bound to iODBC.įor a more detailed Driver Manager comparison, you can check out this Gsheet.Creating a DSN by Adding an Entry in the odbc.ini File ¶ It is somewhat odd that Microsoft chose to tightly couple their ODBC Driver for SQL Server for macOS to UnixODBC, given that Microsoft Excel and Microsoft Query are bound to iODBC, and that Microsoft is aware that macOS ships with iODBC, but different teams there do not always communicate well with each other. Native GUI apps and ODBC drivers that want that native Mac interface – such as Microsoft Excel, and ODBC drivers from many vendors – are therefore linked to iODBC (and typically, but not always, to the iODBC Frameworks rather than the dylibs). On macOS, native GUI ODBC interaction is only available with iODBC. Today, iODBC supports most Unicode encodings – UCS-2, UCS-4 (a/k/a UTF-32), UTF-8, and UTF-32 (a/k/a UCS-4). Basically it is as you all suggested: pyodbc stays the same and is either Windows or unixODBC, pyiodbc is a new project that is always iODBC and is not supported on Windows. Let me know what you all think of this approach. Second, for testing (I don’t want to have to pay to license something for this), is this the right driver? It builds against the unixODBC headers, but won’t work since there are some different data sizes. (Are we sure this is worth the trouble?). If it works, I’ll do the rest with the others (except SS, maybe? we know it is either on Windows or unixODBC).įirst, does anyone now how to properly get the iODBC header files? Their macOS docs are old and I couldn’t find the installer they mentioned. I updated the pgtests file to accept a -library argument to be able to test both.Since changing the interface wasn’t very popular, I’ve created two subdirectories, each with its own setup.py file. ![]() I made a 444-iodbc branch to test building separate pyodbc and pyiodbc projects but I didn’t get very far.
