UnixODBC comes with the isql command to access different DBMS from the command line interpreter. OdbcQuery(ch1, 'select name from master.sysdatabases')Ĭh2 <- odbcConnect(dsn= 'mysql01', uid= 'username', pwd= 'password') Test connections in R: library(RODBC)Ĭh1 <- odbcConnect(dsn= 'sqlserver01', uid= 'username', pwd= 'password') Install RODBC in the R interpreter via install.packages('RODBC'). Test connections in python: import pyodbc as pĬon1 = p.connect( 'DSN=sqlserver01 UID=username PWD=password')Ĭon1.execute( 'select name from master.sysdatabases').fetchall()Ĭon2 = p.connect( 'DSN=mysql01 UID=username PWD=password')Ĭon2.execute( 'show databases ').fetchall() Install pyodbc via sudo pip install pyodbc. # can specify an actual database to each DSN # can't specify username and password for freetds Ruby -e '$( curl -fsSL )' # install freetdsĭriver should be at /usr/local/lib/libtdsodbc.so (symbolic linked).Ĭreate ~/Library/ODBC/odbc.ini: Install via Home Brew: # install homebrew Note: I’m unable to compile the driver from source on Mac OS X.įreeTDS is an open source ODBC driver to access MS SQL Server. Driver should be at /usr/local/lib/libmyodbc5.so or /usr/local/lib/libmyodbc5w.so. I will outline the instructions for setting up MySQL and freeTDS (MS-SQL) drivers for use with RODBC and pyodbc through iODBC. For unixODBC, one could add DSN’s at ~/.odbc.ini.

For iODBC, one could add data source names (DSN’s) at ~/Library/ODBC/odbc.ini. The DBMS drivers used must be compiled for use with iODBC. For example, the R package RODBC and Python package pyodbc are compiled by default to use iODBC on Mac OS X. Whichever one you use, just make sure the DBMS Driver and software you are using are configured/compiled to use with the same ODBC manager (usually set through the configure flags). It doesn’t matter whether you use iODBC or unixODBC.

Different software (e.g., R or Python) can utilize ODBC to access different DBMS through the following logic: Software -> ODBC Manager -> ODBC Driver for the DBMS -> DBMS Server (Software: R, Python, etc. ODBC is kind of like an API for any software to access any DBMS easily, regardless of what DBMS it is and what OS it’s running on. This is the main reason why there’s so much confusion on getting ODBC to work on Mac OS X. Most other Linux/UNIX system uses unixODBC to manage the ODBC drivers. Mac OS X has iODBC installed as it’s default ODBC manager.
