Hi,

Posted something similar to this before, still require help...

I have a table with 60 million rows and am attempting to Insert to a new table based on a Select on the table with 60 million rows.

The query is as follows...

INSERT INTO new_table SELECT * FROM 60_million_rec_table WHERE x BETWEEN * and * AND y BETWEEN * and *

I have the 60 million rows table indexed on the x and y columns.

Currently the query, which is running on my own windows machine, takes on avearage about 90 secs to Insert 100 rows.

Is there any way of speeding this up..?

Regards,
Jorden
