Mysql實現查詢當天、一周、一月，一年的數據

查詢當天的數據

方法一：

SET @dt = CURDATE();
SELECT * FROM table_name WHERE condition1 AND conditions2 AND column_name=@dt;

方法二：

/*使用函數*/
SELECT * FROM table_name WHERE condition1 AND condition2 AND date(column_name)= CURDATE();

方法三：

SELECT * FROM table_name WHERE condition1 AND condition2 AND TO_DAYS(column_name)= TO_DAYS(NOW());

查詢一周的數據

SELECT * FROM table_name WHERE condition1 AND condition2 AND DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(column_name);

方法二：

SELECT * FROM table_name WHERE condition1 AND condition2 AND DATE_SUB(CURDATE(), INTERVAL 1 WEEK) <= date(column_name);

查詢一月的數據

SELECT * FROM table_name WHERE condition1 AND condition2 AND DATE_SUB(CURDATE(), INTERVAL 1 MONTH) <= date(column_name);

查詢一年的數據

SELECT * FROM table_name WHERE condition1 AND condition2 AND DATE_SUB(CURDATE(), INTERVAL 1 YEAR) <= date(column_name);
