SELECT phone from authors WHERE au_name= "Ringer"
When the input is complete, click the Execute Query button (a green triangle that looks like a VCR playback key). When you click this button, any statements that appear in the query window are executed. The query window automatically becomes the result display window, and you can see the results of the query (see Figure 10.3).

The server running environment is Tomcat. The purpose is to allow only specific IP addresses to access a directory,
One way is to use RemoteAddrValve to control access to the VM in the tomcat configuration file server. conf.
You can also use iptables rules. I personally prefer iptables.
For example, to prohibit access to the path http: // 192.168.137.254: 10000/managersns, only access from 192.168.137.101 is allowed.

The server runtime environment is Tomcat and is now implemented to allow only specific IP access to a directory,One approach is to use Remoteaddrvalve to access control of the virtual host in the Tomcat configuration file server.conf.Another way to do this is through iptables rules. Personally prefer IptablesFor example: Access to Http://192.168.137.254:10000/managersns is forbidden and only 192.168.137.101 access is allowed

If you configure SQL Sever to use full security or mixed security, you can use a trusted connection. If you use standard security, you will need to provide a user account and password.
