Autocommit is off by default. If the “dsn” keyword is specified, the other keywords are optional.

Start the build process by extracting the necessary files from the Ingres DBI compressed archive:. An pythno without keywords is shown here:.
Connection pooling non-Windows only The following extended Cursor attributes and methods: If the second member has a value of “None”, the tracing is written to the standard output.
The first member is the tracing level, which can be a value of 0 through 7. The build process has been simplified by the ingress of the Python DistUtils package.
Please review this readme before building or installing this software. All of the above keywords reference string values except for the “trace” keyword. As with the build process, the installation process makes use of DistUtils. For a list of binary downloads, see http: If the database is specified, the other keywords are optional.
Select loops usually have the best performance.
The ability to provide alternate installation locations has not been investigated at this time. For more information, see the Ingres Connectivity Guide. The following values are valid for the “servertype” keyword: For further information, see Python mailing list http: Ingres r3 or above, including Ingres However, only one query string is allowed for each cursor instantiation.
