## Notes

### 2024-07-19

The column name is case insensitive in the dataframe. The column name in the
dataframe is lower case even though the SQL query alias uses upper case (like
`venue_updatedAt` vs `venue_updatedat`)

**Which column is `events_multi_day`?**
```
cat events.old.csv | head -n 1 | awk -F',' '{for(i=1; i<=NF; i++) if($i == "events_multi_day") print i}'
```

**Count multi-day events.**
```
$ zcat events.csv.gz |awk -F',' '$10 == "True"' | wc -l

$ zcat events.csv.gz |awk -F',' '$10 == "False"' | wc -l
