Idea: Generate from column

Postby danfountain » Tue Oct 22, 2013 9:12 am


I have some tables that are not normalised correctly due to being denormalised for OLAP reasons.

So basically i would like to see a way that you can generate for instance a company name, but base it on the data already in the column. Some from of obfuscation. That way the column will still match for all the instances of the same thing.

Many thanks for your products.

Hi Dan,
This should be possible in the next data generator release (v3?). It's been a very popular suggestion to base data in one column from another generated column. For this you will be able to use a CSV of existing data or a Python script for data manipulation. Version 2 introduced Python scripts for manipulating generated data but the ability to retrieve data from another column of generated data does not exist in that version. The only immediate workaround is to compile and add a very complicated Ruby generator to SDG.

Unfortunately I don't have a firm release date for the next version as yet.
