pub fn validate_sql_order_by(order_by: &str) -> Result<(), ParserError>Expand description
Validate the body of an ORDER BY clause (e.g. “ts asc, lsn desc”).
Unlike validate_sql_expression, this accepts the comma-separated,
ASC/DESC/NULLS annotated key list a real ORDER BY allows, and
requires the whole string to parse so a malformed clause fails here rather
than silently dropping every key after the first.
