What is the difference between SYS and system accounts? has been ignorant, just take it for granted that the size of the permission is not the same. However, they are all administrators. Now, I know there's a difference: ' SYS ' can only be logged in as SYSDBA (and perhaps sysoper.) , both the client and the server can"System" can be logged on to the client only as normal, and both normal and SYSDBA are ava

mysql5.7 adds the SYS system database, which provides a quick overview of the system's meta-data. This library does make it easy for DBAs to discover a lot of information about a database, and it can help to solve performance bottlenecks. This library is the default in mysql5.7, which can be imported manually above the mysql5.6 version, and what does the database package find on GitHub by itself? This library is a view of the form of Information_schem
