1 数据库字段pk_time(Varchar)

当天的数据

     SELECT * FROM 表 WHERE date(fk_time) = curdate();

当月的数据

SELECT *FROM 表 WHERE DATE_FORMAT(fk_time,'%Y%m')=DATE_FORMAT(CURDATE( ),'%Y%m')

昨天

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

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();

2 时间段数据

id 为方法名,parameterType参数用map保存,resultType为返回对象 参数tj_start tj_end 提交开始和结束时间

<select id="方法名" parameterType="参数类型" resultType="返回类型">
   select *from jw_order where 1=1            
    <if test="tj_start!= null and tj_start!=''">
     AND submittime&gt;=#{tj_start}
    </if>
    <if test="tj_end!=null and tj_end!=''">
     AND submittime&lt;=#{tj_end}
    </if>
 </select>

3 模糊查询sql(Mybatis)

 <select id="方法" parameterType="参数类型" resultType="返回类型">
 select *from 表名 where 1=1       
 AND 字段 LIKE CONCAT(CONCAT('%', #{参数}), '%')
</select>
