Restoring Deleted Records

After you have deleted records, the records are placed in the Recycle Bin for 15 days, after which they are permanently deleted. While the records are still in the Recycle Bin, you can restore them using the undelete operation. If you accidentally deleted some records that you want to keep, restore them from the Recycle Bin.

Account a = new Account(Name='Universal Containers');
insert(a);
insert(new Contact(LastName='Carter',AccountId=a.Id));
delete a;

Account[] savedAccts = [SELECT Id, Name FROM Account WHERE Name = 'Universal Containers' ALL ROWS]; 
try {
    undelete savedAccts;
} catch (DmlException e) {
    // Process exception here
}
