Hi!
I have a problem with getting the order I want on a table after new rows
have been inserted. I try to simplify it...:
I want to have a one-to-one relationship between 'name' and 'full'.
Every 'name' (or'full') have one or more 'parts'. The higher the 'score'
the lower the 'full', but for my program I have to keep every row with
the same 'name' next to each other, with ascending 'part' number. I
don't want to use 'name' as an identifier since they can be long
sentences.
In other words, I have this old table:
SELECT * from table ORDER BY full,part;
name    full    part    score
----    ---     ---     -----
a       1       1       900
a       1       2       500
b       2       1       800
c       3       1       700
c       3       2       600
c       3       3       500
and I insert these rows into the same table:
(there's nothing I can do about these 'full' values)
d       1       1       1000
d       1       2       400
e       2       1       900
e       2       2       500
f       3       1       700
g       4       1       600
And after some manipulation (that I hope someone can help me with) I
want the query above (SELECT * from table ORDER BY full,part) to give
this:
d       1       1       1000
d       1       2       400
a       2       1       900
e       3       1       900
b       4       1       800
c       5       1       700
c       5       2       600
c       5       3       500
f       6       1       700
g       7       1       600
rather than
a       1       1       900
a       1       2       500
d       1       1       1000
d       1       2       400
b       2       1       800
e       2       1       900
e       2       2       500
c       3       1       700
c       3       2       600
c       3       3       500
f       3       1       700
g       4       1       600
Very grateful for any feedback!
Marcus
