Description:
When I try to connect to a non-existing database with hyphen in the name, the create query failed because the name is not quoted.

How to repeat:
Connect to a non-existing database with hyphen in name and createDatabaseIfNotExist set to true. Example: jdbc:mysql://localhost:3306/my-db?createDatabaseIfNotExist=true

Suggested fix:
In NativeProtocol.java on row 543:

sendCommand(this.commandBuilder.buildComQuery(getSharedSendPacket(), "CREATE DATABASE IF NOT EXISTS " + database), false, 0);

Variable database should be quoted.

Still actual. Can't use createDatabaseIfNotExist on any DB with hyphens in names.

Added the following entry to the C/J 8.0.27 changelog: 

"When the connection property createDatabaseIfNotExist was set to true, a non-existing database could not be created when its name included a hyphen. Thanks to Lukasz Sanek for contributing the fix."
