/datum/database/database/query/proc/GetColumn(column)
Arguments:
column: The 0-based column number to retrieve information from
Returns:
The contents of the given column

Once the query has been run with /database/query/proc/Execute() and we have started to read rows with /database/query/proc/NextRow(), we can retrieve the data stored in a specific column with this proc. To get the names of the columns, /database/query/proc/Columns() can be used.
