For a source pytbon if you wish to build Ingres from source code, see http: Start the build process by extracting the necessary files from the Ingres DBI compressed archive:.

For further information, see Python mailing list http: Enter the newly created source directory, ingresdbi Connection pooling non-Windows only The following extended Cursor attributes and methods: An example without keywords is shown here:.
