In the following SQL:
SELECT * FROM X WHERE Y LIKE "%s"; the % will match any characters before an s. The % can be x, xx, xrf, etc.
Is there any symbol that will only match one character, like:
SELECT * FROM X WHERE Y LIKE "?s" where ? will match only one character like a, b, c, etc.?

SQL pattern matching enables you to use _ to match any single character and % to match an arbitrary number of characters (including zero characters). In MySQL, SQL patterns are case-insensitive by default. Some examples are shown here. Do not use = or <> when you use SQL patterns.
Example - Equality Operator In MySQL, you can use the = operator to test for equality in a query. The = operator can only test equality with values that are not NULL. For example: SELECT * FROM contacts WHERE last_name = 'Johnson';
A wildcard character is used to substitute one or more characters in a string. Wildcard characters are used with the LIKE operator. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column.
In MySQL you do not have ILIKE. Checkout MySQL docs on string comparison functions.
You want to use an underscore (_) character. See the documentation here.
