输出文件的名称是文字，而不是参数，并且不会替换为变量值。此外，文件名必须加引号。
使用准备好的语句：
CREATE EVENT IF NOT EXISTS write_to_log_event
ON SCHEDULE
EVERY 1 DAY
DO
BEGIN
SET @write_to_log_event_sql := CONCAT('SELECT * INTO OUTFILE ''/var/log/sync_db_log_' ,
DATE_FORMAT(NOW(), '%Y%m%d%H%i%S'),
''' FROM sync_logger');
-- SELECT @write_to_log_event_sql; -- for debugging purposes
PREPARE stmt FROM @write_to_log_event_sql;
EXECUTE stmt;
DROP PREPARE stmt;
TRUNCATE sync_logger;
END
PS。TRUNCATE比DELETE快。

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

有用。非常感谢你。
