Selecting data from recordset
I've got a database table (Geo) with the following:
ID: int (Autoindex, primary key)
The table consists of an X/Y grid of data.
While I can do individual queries like "SELECT Home from Geo WHERE X=345 and Y=972" to get an individual value for Home, it's a pretty large grid (1000x1000, a million records), so I'm thinking it will probably quicker to do a query like:
SELECT X,Y,Home FROM Geo WHERE (X BETWEEN 50 and 80) and (Y BETWEEN 200 and 220)
Then somehow select from the recordset using the X & Y values. But I have no idea how to "query" the recordset based on values in the recordset. Hoping someone out there will know how!
Also, is there a good way to move the two dimensional data in the recordset into a two dimensional array?
Thanks in advance!
