Hi,
I have a query which is needed to run monthly, which pick all the relevant information about all the available policies from different tables and dump all the records into a table for further processing.
The problem is, there are about 6,00,000 policies in the database, and fetching this number of records and dumping the same in a table is really...
Now i want to know the best approach to do this. At query level it is properly tuned. now the question is should i use a single query e.g. insert into select ... or should i go for a cursor and issue commit after some number of records? Along with all that also suggest me about how to reduce the total time taken by the query.
