2it depends on whether the table and column use case-insensitive collation. – Barmar Feb 07 '22 at 17:09

Case-sensitivity is determined by the collation of a column. The default collations are case-insensitive, so the string comparison you show would match both "sql" and "SQL".
Read https://dev.mysql.com/doc/refman/8.0/en/case-sensitivity.html
If your column has a binary collation, or if the column is a binary string (data types BINARY, VARBINARY, BLOB), then the string comparison will be case-sensitive.
