The following is my understanding. please correct me if there is anything wrong:
String S = SC. nextline ();Here we read an empty string.

Index full scan and index fast full scan look similar to each other. They are both common and personalized. The commonality between the two is that scanning is not required.You can directly return all the required data through the index. This is undoubtedly one of the rare data access methods to improve query performance, because the data stored in the index is usuallyIs much smaller than the original table
In front, you Xia introduced some knowledge about database vulnerability scanning and launched an "Authorization scan" for Oracle databases. Now we perform a "weak password scan ", because weak passwords are almost the biggest threat to databases, we listed "weak password scanning" in database vulnerability scanning ". The target of this project is still the Oracle database.

1) Full Table scan (Full Table Scans, FTS)To scan the entire table, Oracle reads all rows in the table and checks whether each row meets the WHERE restrictions of the statement. Oracle reads each data block allocated to the table sequentially until it reads the highest waterline of the table (high water mark, HWM, marking the last data block of the table ). One multi-block read operation enables I/O to read
