MySQL中可以使用ORDER BY子句对结果集进行排序，可以使用WHERE子句对结果集进行过滤。以下是一些常用的排序和过滤技巧：
SELECT * FROM table_name ORDER BY column_name;
SELECT * FROM table_name ORDER BY column1, column2;
SELECT * FROM table_name ORDER BY column_name ASC;
SELECT * FROM table_name WHERE column_name = 'value';
SELECT * FROM table_name WHERE column1 = 'value1' AND column2 = 'value2';
SELECT * FROM table_name WHERE column_name LIKE 'value%';
SELECT * FROM table_name WHERE column_name IN ('value1', 'value2', 'value3');
SELECT * FROM table_name WHERE column_name BETWEEN value1 AND value2;
通过以上技巧，可以灵活地对MySQL的结果集进行排序和过滤，满足不同的查询需求。
