Ping an interview review of science and technology

Time:10-23

Today went to the safe application of nanshan operations engineer interview, I feel very bad...

Remember the two problems, a script, SQL, you can try to solve the (didn't write to, I'm too food two SQL was not very hard, also lost for a long time to forget)
SQL:
A table A, B, A field of c, d B have field e, f, please try to A.c=B.e in a. d. value refresh into b.
Script:
With the directory/var/cache saved up some logs to the absolute path to the folder below for
The/var/cache/month/date/log/XXX. The log
Such as/var/cache/201903/20190325/log/root. The log
Otherwise the backup directory/bar/backup/month/date/log/XXX. The log

Requirements: log and the time of the day time in the backup directory, please move the log files within seven days to the corresponding backup directory, do not need to be compressed
