RE: [sqlite] Sorted index

2007-06-05 Thread Tom Briggs

   When querying the table be sure to put the indexed column(s) in the
ORDER BY clause though - otherwise the index won't do you any good. :)

Re: [sqlite] Sorted index

B-Tree indices are in sorted sequence.  Just raise an index on the column.

I would like to maintain a sorted list of ~3000 entries.
I know that I can create a table and the SELECT from it with the ORDER BY clause
in order to sort it.
However I do not want the overhead of doing this after adding a new entry.
It would be good if I could create an index that was sorted, and then when I
add a new entry to the table it would automatically be inserted in the index at
the correct position.
Is this possibe?
If not, can anyone suggest any other solution, baring in mind that RAM memory
needs to be kep to a minimum?

Thanks
Clive
