Display different variables in MySQL using LIKE?

Following is the syntax −

show variables where Variable_name like 'yourVariable1%' or Variable_name like 'yourVariable2%',.............N;

Let us implement the above syntax to show(more than one) variables −

mysql> show variables where Variable_name like 'key%' or Variable_name like 'innodb_undo%' or Variable_name like 'innodb_log%';

Output
