Re: can't get the order I want after inserting new rows

Yes, that's exactly it. There's no mistake. The only column I need to
update is 'full', by giving every row a new 'full', based on its
'score'. The tricky thing is that if a 'name' has several 'parts', then
all those 'parts' should have the same new 'full' value. Not sure if I'm
making much sense here...Just ask away if it's still unclear.

I'm trying to summarize parsed outputs from the bioinformatics
application 'blast', where 'name' is hit-name, 'full' is hit, and 'part'
is sub-hits called HSPs (within the same hit). Score is score.

If I was doing it by hand I would sort the rows descending according to
score, and give them new 'full' values, starting from 1. But if a 'name'
has more than one 'part' I would give them the same new 'full' value as
its first 'part', even if they would have lower scores.

Actually, I could add the new data in two different ways. Either as
before:

d       1       1       1000
d       1       2       400
e       2       1       900
e       2       2       500
f       3       1       700
g       4       1       600

or (by using the old data's highest 'full' as offset)

d       3       1       1000
d       3       2       400
e       5       1       900
e       5       2       500
f       6       1       700
g       7       1       600


The table defintion would be
CREATE TABLE table(name TEXT NOT NULL,full INTEGER,part INTEGER)

Hope I haven't confused you more...;)
