The iussue:
Sql 2K
I have to keep in the database the data from the last 3 months.
Every day I have to load 2 millions records in the database.
So every day I have to export (in an other database as historical data
container) and delete the 2 millions records inserted 3 month + one day ago.
The main problem is that delete operation take a while...involving
transaction log.
The question are:
1) How can I improve this operation (export/delete)
2) If we decide to migrate to SQL 2005, may we use some feature, as
"partitioning" to resolve the problems ? In oracle I can use the "truncate
partition" statement, but in sql 2005, I'm reading, it cant be done.
This becouse we can think to create a partition on the last three mounts to
split data. The partitioning function can be dinamic or containing a
function that says "last 3 months ?" I dont think so.
May you help us
thank you
Mastino
