Foundation Db2 and Python: Access Db2 with Module-Based API Examples Using Python de W. David Ashley

Foundation Db2 and Python: Access Db2 with Module-Based API Examples Using Python

Autor W. David Ashley
en Limba Engleză Paperback – 5 aug 2021
Work with Db2 to write SQL and access databases using optimized code for the fastest response. This book will give you complete documentation on DB2 via Python for the IBM_db module and provide a number of examples for the usage of each module API.

Begin by getting your free version of Db2 for Linux and Windows. While the book concentrates more on the Linux version of Db2, it also covers enough of the Windows version so that you're comfortable with obtaining and installing Db2 on your version of Windows. Next, you'll see how to install the sample database that comes with Db2, and take some data from the web to design a database around it, including tables and indexes.

For Db2 to be really useful you need to use strong SQL expressions. This book provides specific examples of how to avoid using poor ones that can cause extra processing time for the query. Lastly, you'll look at each API in the ibm_db and ibm_db_dbi module. This module is not sponsored by IBM and must be installed separately from the Db2 database.

After reading Foundation Db2 and Python you'll be able to install Db2 on Windows or Linux, and perform backups and restore data. 

What You'll Learn
  • Obtain and install Db2 properly on Linux and Windows
  • Create databases and load them on Db2
  • Work with ibm_db and ibm_db_dbi API modules for Python
  • Write SQL for Db2
  • Review the future of the ibm_db Python module
