QUESTION
Morning All
Ok so I know how to get the percentage using like.
...ANSWER
Answered 2018-Jan-15 at 08:37This is a tricky question, because to obtain the percentages of each group (requiring one aggregation) we need to normalize those counts with the total count of the entire query (another aggregation). One approach is to place the base join query into a CTE. Then, query that CTE and also get the total count via a subquery on the same CTE.

Install pywk
You can use pywk like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
