T-SQL: Selecting rows to delete via joins

DELETE TableA
FROM   TableA a
       INNER JOIN TableB b
               ON b.Bid = a.Bid
                  AND [my filter condition]

should work

I would use this syntax

Delete a 
from TableA a
Inner Join TableB b
on  a.BId = b.BId
WHERE [filter condition]

Yes you can. Example :

DELETE TableA 
FROM TableA AS a
INNER JOIN TableB AS b
ON a.BId = b.BId
WHERE [filter condition]
