The repository contains scripts in various languages with SQL queries as practice.
The datasets are taken from a homework set for one of the classes of my Master's program. The homework consisted of various SQL queries done in SAS, most of which I have replicated and modified in the various scripts. The datasets originate from the sql.cpo file in data. I wrote a SAS script (src/extract_data.sas) to extract the datasets from this proprietary SAS format and save the tables as CSV files.
