當(dāng)天
SELECT * FROM 表名 WHERE TO_DAYS(時間字段名) = TO_DAYS(NOW());

昨天
SELECT * FROM 表名 WHERE TO_DAYS(NOW()) - TO_DAYS(時間字段名) <= 1;

本周
SELECT * FROM 表名 WHERE YEARWEEK(DATE_FORMAT(時間字段名,'%Y-%m-%d')) = YEARWEEK(NOW());

上周
SELECT * FROM 表名 WHERE YEARWEEK(DATE_FORMAT(時間字段名,'%Y-%m-%d')) = YEARWEEK(NOW())-1;

近7天
SELECT * FROM 表名 WHERE DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= DATE(時間字段名);

近30天
SELECT * FROM 表名 WHERE DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= DATE(時間字段名);

本月
SELECT * FROM 表名 WHERE DATE_FORMAT(時間字段名,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m');

上個月
SELECT * FROM 表名 WHERE PERIOD_DIFF(DATE_FORMAT(NOW(),'%Y%m'),DATE_FORMAT(時間字段名,'%Y%m')) = 1;

SELECT * FROM 表名 WHERE DATE_FORMAT(時間字段名,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m') ;?

SELECT * FROM 表名 WHERE WEEKOFYEAR(FROM_UNIXTIME(時間字段名,'%y-%m-%d')) = WEEKOFYEAR(NOW());?

SELECT * FROM 表名 WHERE MONTH(FROM_UNIXTIME(時間字段名,'%y-%m-%d')) = MONTH(NOW());?

SELECT * FROM 表名 WHERE YEAR(FROM_UNIXTIME(時間字段名,'%y-%m-%d')) = YEAR(NOW()) AND MONTH(FROM_UNIXTIME(時間字段名,'%y-%m-%d')) = MONTH(NOW());

近6個月
SELECT * FROM 表名 WHERE 時間字段名 BETWEEN DATE_SUB(NOW(),INTERVAL 6 MONTH) AND NOW();

本季度
SELECT * FROM 表名 WHERE QUARTER(時間字段名) = QUARTER(NOW());

上季度
SELECT * FROM 表名 WHERE QUARTER(時間字段名) = QUARTER(DATE_SUB(NOW(),INTERVAL 1 QUARTER));

本年
SELECT * FROM 表名 WHERE YEAR(時間字段名)=YEAR(NOW());

去年
SELECT * FROM 表名 WHERE YEAR(時間字段名) = YEAR(DATE_SUB(NOW(),INTERVAL 1 YEAR));

Oracle幾個常用的日期計算SQL示例

1、查詢上月的所有日期：SELECT TO_CHAR (TRUNC (TRUNC (SYSDATE, 'MM') - 1, 'month') + LEVEL - 1,'yyyy-MM-dd')AS month_dayFROM DUALCONNECT BY LEVEL <= TO_CHAR (LAST_DAY (TRUNC (SYSDATE, 'MM') - 1), 'dd');2、查詢當(dāng)月的所有日期：SELECT TO_CHAR (TRUNC (SYSDATE, 'month') + LEVEL - 1,'yyyy-MM-dd')AS month_dayFROM DUALCONNECT BY LEVEL <= TO_CHAR (LAST_DAY (TRUNC (SYSDATE, 'MM') - 1), 'dd');3、查詢上月月份：SELECT TO_CHAR(ADD_MONTHS(SYSDATE,-1),'YYYY-MM') FROM DUAL; 4、查詢當(dāng)月天數(shù)：SELECT TO_CHAR (LAST_DAY (TRUNC (SYSDATE, 'mm')), 'DD') mounth_countFROM DUAL;5、查詢當(dāng)月第一天：SELECT TRUNC (SYSDATE, 'month') FROM DUAL;6、查詢當(dāng)月最后一天：SELECT TO_CHAR (LAST_DAY (SYSDATE), 'YYYY-MM-DD') FROM DUAL;7、計算兩個日期之間天數(shù)：SELECT   TO_DATE ('2013-08-05', 'yyyy-MM-dd')- TO_DATE ('2013-08-01', 'yyyy-MM-dd')+ 1AS count_dayFROM DUAL;8、查詢兩個日期之間的所有日期：SELECT ROWNUM, TO_DATE ('2013-01-02', 'yyyy-MM-dd') + ROWNUM - 1 AS alldayFROM DUALCONNECT BY ROWNUM <TO_DATE ('2013-01-07', 'yyyy-MM-dd')- TO_DATE ('2013-01-02', 'yyyy-MM-dd')+ 2;
