在開發中，我們經常需要從數據庫中查詢數據。MySQL作為其中一個常用的關系型數據庫管理系統，提供了豐富的查詢語句來實現各種查詢需求。

下面就來介紹一些常見的MySQL查詢語句。

-- 1. SELECT查詢SELECT column1, column2, ... FROM table_name WHERE condition;-- 2. INSERT插入INSERT INTO table_name (column1, column2, ...) VALUES (value1, value2, ...);-- 3. UPDATE更新UPDATE table_name SET column1 = value1, column2 = value2, ... WHERE condition;-- 4. DELETE刪除DELETE FROM table_name WHERE condition;-- 5. LIMIT限制查詢結果數量SELECT column1, column2, ... FROM table_name LIMIT num;-- 6. ORDER BY排序SELECT column1, column2, ... FROM table_name ORDER BY column1 [ASC|DESC];-- 7. GROUP BY分組SELECT COUNT(*) AS count, column1 FROM table_name GROUP BY column1;-- 8. JOIN連接多張表SELECT table1.column1, table2.column1 FROM table1 JOIN table2 ON table1.join_column = table2.join_column;

以上就是MySQL中常見的查詢語句，希望在實際開發中可以有所幫助。
