js获取当前月后面12个月–返回所有月份
    var dataArr = [];
    var data = new Date();
    var year = data.getFullYear();
    data.setMonth(data.getMonth() + 1, 1); //获取到当前月份,设置月份
    for (var i = 0; i < 12; i++) {
        data.setMonth(data.getMonth() - 1); //每次循环一次 月份值减1
        var m = data.getMonth() + 1;
        m = m < 10 ? "0" + m : m;
        dataArr.push(data.getFullYear() + "-" + m);
    }
    console.log(dataArr);

留个记录。。
获取当前月数据
SELECT *FROM 表 WHERE DATE_FORMAT(字段名,'%Y%m')=DATE_FORMAT(CURDATE(),'%Y%m)
SELECT *FROM 表 WHERE PERIOD_DIFF(DATE_FORMAT(CURDATE(),'%Y%m),DATE_FORMAT(字段名,'%Y%m'))=0

获取下个月数据
SELECT *FROM 表 WHERE PERIOD_DIFF(DATE_FORMAT(CURDATE(),'%Y%m),DATE_FORMAT(字段名,'%Y%m'))=-1 //以年月为维度

例如当前时间为2018-07-02 则取数据范围为2018-08-01至2018-08-31
SELECT *FROM 表 WHERE PERIOD_DIFF(DATE_FORMAT(CURDATE(),'%m),DATE_FORMAT(字段名,'%m'))=-1 //以月为维度


今天
select * from 表名 where to_days(时间字段名) = to_days(now());

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

近7天
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

查询本季度数据
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());

查询上季度数据
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

查询本年数据
select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());

查询上年数据
select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));

查询当前这周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());

查询上周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;

查询上个月的数据
select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m')

select * from user where DATE_FORMAT(pudate,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m') ; 

select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now()) 

select * from user where MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) 

select * from user where YEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = YEAR(now()) and MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) 

select * from user where pudate between  上月最后一天  and 下月第一天 

查询当前月份的数据
select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')

查询距离当前现在6个月的数据
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();

js根据当前日期获取当前月的第一天和最后一天

/**
 * 获取当前月的第一天
 * @returns {string}
 */
function getCurrentMonthFirst(d){
    var date = new Date(d);
    date.setDate(1);
    var month = parseInt(date.getMonth()+1);
    var day = date.getDate();
    if (month < 10) {
        month = '0' + month
    }
    if (day < 10) {
        day = '0' + day
    }
    return date.getFullYear() + '-' + month + '-' + day;
}

/**
 * 获取当前月的最后一天
 * @returns {Date}
 */
function getCurrentMonthLast(d){
    var date=new Date(d);
    var currentMonth=date.getMonth();
    var nextMonth=++currentMonth;
    var nextMonthFirstDay=new Date(date.getFullYear(),nextMonth,1);
    var oneDay=1000*60*60*24;
    var lastTime = new Date(nextMonthFirstDay-oneDay);
    var month = parseInt(lastTime.getMonth()+1);
    var day = lastTime.getDate();
    if (month < 10) {
        month = '0' + month
    }
    if (day < 10) {
        day = '0' + day
    }
    return date.getFullYear() + '-' + month + '-' + day;
}

调用该方法

//获取当前日期
        var currentDate_mon = new Date();
        //获取当前月的第一天
        var currentMonthFirst = getCurrentMonthFirst(currentDate_mon);
        //获取当前月的最后一天
        var currentMonthLast = getCurrentMonthLast(currentDate_mon);
