MySQL does not directly support a command to “show available”, but here’s how you can find out various types of information:

– **Show databases:** To see all the databases you have access to, you can use:
“`mysql
SHOW DATABASES;
“`
– **Show tables:** To see all the tables in the currently selected database, you can use:
“`mysql
SHOW TABLES;
“`
– **Show users:** To see all MySQL server users, you need permissions to access the ‘mysql’ database. Then you can use:
“`mysql
SELECT User, Host FROM mysql.user;
“`
– **Show processlist:** To see which threads are running, you can use:
“`mysql
SHOW PROCESSLIST;
“`
– **Show status:** To see server status information, you can use:
“`mysql
SHOW STATUS;
“`
– **Show variables:** To see server system variables, you can use:
“`mysql
SHOW VARIABLES;
“`
Remember that you’ll need appropriate privileges to perform these operations.
