Hi
I'm somewhat new to Python and SQLObject (but have worked with ORM Wrappers
before with Java). I have inherited a project which uses the above
extensively. I have a somewhat novice question but couldn't find obvious
answers so am posting here.
So the code I have basically does a .select() on a merge table and creates
an output file (Comma separated say) with columns I'm interested in . I want
to now additionally mark in this file -
a. duplicates that occur in succession only
b. objects that have certain values for a column
So for eg, if row X and row Y are duplicates, I want to have in the file a
single row with the letter D at the end to mark Duplicate.
Whats the best way of doing this?
I thought of this pseudo-code:
for x in merge_table.select()
retrieve next row y ->> (how??)
if x==y //duplicate
add x to file & mark appropriately in file
else
add x and y to file
reposition cursor correctly to next unread row (if needed, how?)
I was trying to find a way to do this with SQLObject but couldn't easily
figure out. I would like to avoid complicated cursor logic if I can help it.
Any pointers would be appreciated.
TIA,
CV
