If you want to perform bunch of updates/insert at once ,then we can go for batch.
The entire bunch can be bundled into a single transaction so that entire unit can be commited/rolledback.
Hi swathi
batchUpdate() is for executing more than one query at a time.
Adavatange is,for every sql query u need not send to DB server.
There no n/w traffic b/w client and DB server.So performance wil increase.
