```
    从接口复制的说明: JdbcDialect
    
    Constructs the dialects upsert statement if supported; such as MySQL's DUPLICATE KEY UPDATE, or PostgreSQL's ON CONFLICT... DO UPDATE SET...
    If supported, the returned string will be used as a PreparedStatement. Fields in the statement must be in the same order as the fieldNames parameter.
    If the dialect does not support native upsert statements, the writer will fallback to SELECT ROW Exists + UPDATE/INSERT which may have poor performance.
    
    指定者:
