Same name and namespace in other branches
  1. 8.0 core/lib/Drupal/Core/Database/Driver/sqlite/Connection.php \Drupal\Core\Database\Driver\sqlite\Connection::sqlFunctionLikeBinary()

SQLite compatibility implementation for the LIKE BINARY SQL operator.

SQLite supports case-sensitive LIKE operations through the 'case_sensitive_like' PRAGMA statement, but only for ASCII characters, so we have to provide our own implementation with UTF-8 support.
