3)Questions: How I write a query make to delete records? From table 'old_data' delete match records reference to table 'current_data' and keep the remain good records are from 'current_data' table.

****Here's below my test query that came up with if there are any error and please provide me any suggestion or new query. Very important task ....Thanks you to all.

/*******

From old_data Cross Join current_data
Where old_data.FirstName = current_data.FirstName and old_data.LastName = current_data.LastName
and old_data.Address = current_data.Address
