very poor, because the database must compare the data one by one when encountering these two statements, if there are tens of thousands of data records on both sides of the in or not in, the number of comparisons is hundreds of millions. It is very likely that a simple SQL statement will be executed for more than half an hour. This efficiency is certainly unacceptable to customers. We can consider two alternative methods. The first one is to use the exist statement and not exist statement, whic
