Hi,
I wondered if anyone could answer the following question:
If I have a table such as the one below:
col1 col_order
-----------
Apple 1
Apple 2
Orange 3
Banana 4
Apple 5
Is there a way I can get the following results:
Apple 2
Orange 1
Banana 1
Apple 1
i.e. Each row is printed ordered by col_order but consecutive
appearances of the same col1 result in only a single line in the result
with the number of consecutive appearances.
Obviously I could store the table as:
col1 col_order col_count
--------------------------
Apple 1 2
Orange 2 1
Banana 3 1
Apple 4 1
But since (in my intended table) most rows will have col_count = 1, this
seems like unnecessary normalization (and semantically "wrong").
Thanks in advance for any help,
Leon Stringer
