Metamart SQL Server Integration

The SQL Server integration synchronizes metadata from your SQL Server database into your Metamart data lineage graph.

Tests assume you have working installation of pyodbc and a supported ODBC driver installed on your host machine.

Installation Notes

Installing ODBC drivers can be particularly tricky on M1 machines. You'll need to install the unixodbc drivers through brew first

    brew install unixodbc

You can attempt installing pyodbc directly at this point though I was forced to set LDFLAGS and CPPFlags in my bashrc/zshrc file, i.e.

export LDFLAGS="$LDFLAGS -L$(brew --prefix unixodbc)/lib"
export CPPFLAGS="$CPPFLAGS -I$(brew --prefix unixodbc)/include"

At this point you should be able to pip install pyodbc successfully and import the package from within python. However, you'll still require an ODBC driver in order to connect with an MS SQL server. There are multiple options for potential drivers but ODBC 18 from Microsoft has worked in testing.

brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
HOMEBREW_ACCEPT_EULA=Y brew install msodbcsql18 mssql-tools18

If you continue to experience issues you might try creating these symlinks below.

sudo ln -s /opt/homebrew/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /opt/homebrew/etc/odbc.ini /etc/odbc.ini

When installing locally, if you get an error like ImportError: dlopen(/opt/homebrew/lib/python3.11/site-packages/pyodbc.cpython-311-darwin.so, 0x0002): symbol not found in flat namespace (_SQLAllocHandle), you can try uninstalling pip uninstall pyodbc and then reinstall with build pip install --no-binary :all: pyodbc.
