mysql删除表的前10000行的几种方法，

有以下几种方法可以删除 MySQL 表的前 10000 行：

1. 使用 DELETE 命令和 LIMIT 子句

DELETE FROM table_name LIMIT 10000;

2. 使用子查询和 DELETE 命令

DELETE FROM table_name WHERE id IN (SELECT id FROM table_name LIMIT 10000);

3. 使用临时表

CREATE TEMPORARY TABLE tmp_table_name SELECT * FROM table_name LIMIT 10000;
TRUNCATE table_name;
INSERT INTO table_name SELECT * FROM tmp_table_name;
DROP TEMPORARY TABLE tmp_table_name;

4. 使用游标

DECLARE cursor_name CURSOR FOR SELECT * FROM table_name LIMIT 10000;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
OPEN cursor_name;
REPEAT
    FETCH cursor_name INTO @var1, @var2, ...;
    DELETE FROM table_name WHERE CURRENT OF cursor_name;
UNTIL done END REPEAT;
CLOSE cursor_name;

需要注意的是，以上方法都有一定的风险，操作前应该先备份数据。另外，如果表中有外键约束，需要先删除相关的子表数据。
