Hi
There are many ways to improve the performance of fetching records from a table which 1 million records. This cannot be achieved using just a PL/SQL code even the database design has to adhere to it.
1) Table can be partitioned
2) Necessary index
3) Gather stats for the table regularly
After this, the PL/SQL code has to be written in such a way to prune the partition and use the appropriate index. You can see significant improvement in the performance.
