T-SQL (SS2K8) :: Get Delta Records Between 2 Tables With Same Structure

I need to get the replacement records between the 2 tables. I have table A and table B with same structure. I have 5 fields. Table A has 50,000 records and table B has 20,000 records. I have fields id , name, address,meter_flag,end_Date.

Some of the records in Table B are just replacement records of table A. I mean for example I have records like this in Table A

id name address meter_flag end_date

23 john 1201 salt lake dr no 2011-12-28

24 tom 1222 gibson ln yes 2011-12-16

25 alex 1334 qayak dr no 2011-12-17

In Table B

23 john 1344 mc kinney st yes 2011-12-18

24 tom 1222 gibson ln yes 2011-12-16

56 gary 1335 pruitt rd no 2011-12-18

25 alex 1334 qayak dr no 2011-12-17

So here in Table B i have an update for john with id 23 in table A in address field and meter_flag has changed to yes. There is new record with id 25 in table b but that is not in table A. so I need to find all these difference records by querying these 2 table
