I'd appreciate learning how to correctly write a SELECT statement that
reports the SUM of one returned column.
I can select all relevant rows, but don't know where to put the
SUM(distance) phrase:
SELECT l.llid, l.name, s.endKM - s.beginKM AS distance
FROM lotic AS l, streamlength AS s
WHERE l.llid = s.llid and l.llid = '1226038453652';
I would like SQL to do the work of summing the derived column 'distance'
for me.
