Hi,
I'm not replying with an answer, but with a similar problem. I am using a
TRAC database on top of a SQLite DB and I want to provide a percentage of
the sum total hours/sum estimated hours. Here's what I'm seeing.
- when only one value (a natural number) is summed and divided, the answer
is 0 (should be 73/100=73%).
- when multiple lines are summed and divided && the some of the lines have
fractions (like 7.25, 1.33, etc.), then the answer is correct.
- when multiple lines are summed and divided && the lines are all natural
numbers, then the answer is 0.
My query is below. Does this make any sense?
SELECT __color__, __group__, __style__, ticket, summary, component ,
__milestone__, status, owner, Estimated_work, Total_work,
Percentage_Complete, _ord

SELECT p.value AS __color__,

'' as __style__,

CASE WHEN EstimatedHours.value = '' OR EstimatedHours.value IS NULL
THEN 0
ELSE CAST( EstimatedHours.value AS DECIMAL ) END as Estimated_work,
CASE WHEN totalhours.value = '' OR totalhours.value IS NULL THEN 0
