批量刪除數據可以使用DELETE語句結合IN、BETWEEN、LIKE等條件進行操作，也可以使用子查詢來實現批量刪除。以下是一些常用的批量刪除技巧：
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;
請注意，在執行批量刪除操作時應格外小心，避免誤刪重要數據。建議先備份數據或者使用事務來確保數據的安全性。
