MySQL 统计当天、一周、一月等的数据

 

## NOW() 函数返回当前的日期和时间 ( 执行SQL语句时的时间 )
SELECT NOW();

## CURDATE() 函数返回当前的日期
SELECT CURDATE();
## CURTIME() 函数返回当前的时间
SELECT CURTIME();
## CURRENT_DATE() 函数返回当前的日期
SELECT CURRENT_DATE();
SELECT CURRENT_DATE;
## CURRENT_TIME() 函数返回当前的时间
SELECT CURRENT_TIME;
SELECT CURRENT_TIME();
## CURRENT_TIMESTAMP 是NOW的同义词 函数返回当前的日期和时间
SELECT CURRENT_TIMESTAMP();
SELECT CURRENT_TIMESTAMP;

## 当前日期和时间其他的 是MySQL的
SELECT LOCALTIME();
SELECT LOCALTIMESTAMP();
SELECT SYSDATE();

## UNIX_TIMESTAMP() 转为时间戳 -- 1天86400秒 时间戳以 秒 为单位
-- 返回当前时间的UNIX格式数字串，或者说是 UNIX 时间戳（从 UTC 时间'1970-01-01 00:00:00'开始的秒数），通常为十位，如 1344887103。
SELECT UNIX_TIMESTAMP(NOW()); -- 当前的时间戳
SELECT UNIX_TIMESTAMP(LEFT(NOW(),10)); -- 当天00:00:00 秒的时间戳
SELECT UNIX_TIMESTAMP(CURRENT_DATE); -- 当天00:00:00 秒的时间戳
SELECT UNIX_TIMESTAMP(CURRENT_DATE()); -- 当天00:00:00 秒的时间戳

SELECT UNIX_TIMESTAMP(CURRENT_DATE) + 86399; -- 当天23:59:59 秒的时间戳
SELECT UNIX_TIMESTAMP(CURRENT_DATE()) + 86399; -- 当天23:59:59 秒的时间戳
SELECT UNIX_TIMESTAMP(CONCAT(CURDATE(),' ','23:59:59')); -- 当天23:59:59 秒的时间戳 拼接
SELECT UNIX_TIMESTAMP(DATE_ADD(CURRENT_DATE, INTERVAL 86399 SECOND)); -- 当天23:59:59 秒的时间戳 -- 当天的00:00 向后+86399秒
SELECT UNIX_TIMESTAMP(DATE_ADD(CURRENT_DATE, INTERVAL 1 DAY)) - 1; -- 当天23:59:59 秒的时间戳 -- 当天的00:00 向后的一天 减1秒

 

今天

SELECT * FROM 表名 WHERE TO_DAYS(时间字段名)=TO_DAYS(NOW());

SELECT * FROM 表名 WHERE TO_DAYS(时间字段名)=TO_DAYS(CURRENT_DATE());

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) = 1;

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) = TO_DAYS( 时间字段名) + 1;

近7天

SELECT * FROM 表名 WHERE TO_DAYS(CURDATE()) - TO_DAYS(时间字段名)<=7;

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名);

近30天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)

本月

SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )

上一月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 时间字段名, '%Y%m' ) ) =1
