def date_format(timestamp, format) -> Expression:
"""
Formats a timestamp as a string using a specified format.
- The format must be compatible with MySQL's date formatting syntax as used
by the
- date_parse function.
Review Comment:
@davidradl , the comment I deleted is not accurate.
MySQL's date formatting syntax follows its own date formatting syntax, not
Java's `SimpleDateFormat` or `DateTimeFormatter`. MySQL is written in C++, not
Java, and doesn't have much significance as a reference here.
