HI everybody,

I have two database tables

Animal1
ID                  Type               Name
1                    cat                   felix
2                    dog                   ruff
3                    dog                   rover
4                    dog                   skip
5                    cat                    heathcliff

Animal2
ID                 type                   Name
1                  cat                     felix
4                   dog                   skip
3                  horse                   ED

Now if i have duplicate records in both tables I need to delete the duplicates from the "animal2" table. How can i do that?  Is there a way to write a query to do this?
