Project Overview

Main SQL file location

Ranking.sql

This file works on the database cities.

However, the cities database takes vc data from vcdb2. See VC Database Rebuild for information on the build.

The output from vcdb2 is roundleveloutput2, which is exported as roundleveloutput2.txt

roundleveloutput2.txt is imported into cities as roundleveloutput2, and then left joined with populationtablecorrected.

Last Population SQL file location

Z:\Hubs\2017\sql scripts

Population issue

One issue is that cities without populations in populationtablecorrected but in roundleveloutput2 get dropped later. For example, roundleveloutput2 contains Brooklyn, NY but populationtablecorrected doesn't (its New York count is therefore suspect too).

populationtablecorrected is loaded from files 'population1.txt' and 'population2.txt'. Dups are removed with a max.

'population1.txt' and 'population2.txt' are in:

Z:\Hubs\2017\clean data\Population

Their construction notes are on Hubs#Population_Data
