That's a great question! Besides the _ (underscore) and % (percent) wildcards, there are no other standard wildcards for the LIKE operator in SQL.
The _ and % are the only two special characters universally used for pattern matching with LIKE across most SQL database systems.
However, some database systems might offer extended regular expression capabilities through other operators (like REGEXP or RLIKE in MySQL, or ~ in PostgreSQL) which provide more powerful pattern matching features. But for the standard LIKE operator, it's just the _ and %.
Do you have any specific pattern matching you're trying to achieve? Knowing that might help me guide you to the right tools!
