批量删除数据可以使用DELETE语句结合IN、BETWEEN、LIKE等条件进行操作，也可以使用子查询来实现批量删除。以下是一些常用的批量删除技巧：
DELETE FROM table_name
WHERE column_name IN (value1, value2, value3, ...);
DELETE FROM table_name
WHERE column_name BETWEEN value1 AND value2;
DELETE FROM table_name
WHERE column_name LIKE 'pattern';
DELETE FROM table_name
WHERE column_name IN (SELECT column_name FROM other_table WHERE condition);
DELETE t1
FROM table_name1 t1
JOIN table_name2 t2 ON t1.column_name = t2.column_name
WHERE condition;
请注意，在执行批量删除操作时应格外小心，避免误删重要数据。建议先备份数据或者使用事务来确保数据的安全性。
