27.4.5.2 The extract_table_from_file_name() Function
Given a file path name, returns the path component that represents the table name.
This function is useful when extracting file I/O information from the Performance Schema that includes file path names. It provides a convenient way to display table names, which can be more easily understood than full path names, and can be used in joins against object table names.
Parameters
path VARCHAR(512): The full path to a data file from which to extract the table name.
