How can I get a count at the same time I am inserting into another table

Question

I have a requirement where I have to find out the count(number of records inserted into another table) at the same time I insert into the table:
Like
I am copying records from table B to A, while doing this I have to find out how many records I've inserted since I need this count in subsequent steps
INSERT INTO A
SELECT * FROM B
how can I store the count into any variable while doing above statement
Please advice
