HOW TO GET THE LATEST DATA IN SCD ?..

Answer / bidhar

In SCD 2 you must be generating the surrogate keys.
Example:
Customername Address Customer_id Customer_identifier
Amit Bangalore 100 10
Amit Hyderabad 100 11
Amit Pune 100 12
Amit Mumbai 100 13

Here column Customer_identifier is the surrogate key.
so for latest record ,you can pick up the record which have
maximum surrogate key value(13).

Let me know if i am wrong.
