Time range query in mybatis

an oracle database

The database time type is DATE
Insert image description here
TO_CHAR Convert the date or number to a string
TO_DATE Convert the string to the date type in the database TO_DATE(char, 'format')
TO_NUMBER Convert the string to a number TO_NUMBER(char, 'format')

1. The input parameter is String type data.

Use the TO_DATE function to convert the String type time into the yyyy-MM-dd format time.
There will be problems with time range queries in this way. The = sign will be invalid at this time, because VOUCHER_TIME is specific to hours, minutes and seconds, and TO_DATE(#{jyzbLedger.voucherTimeFrom},'yyyy-MM-dd') is lost when it is converted into time. Hours, minutes and seconds cause the == judgment to be invalid. Eventually the equivalent data is lost

  <if test="jyzbLedger.voucherTimeTo != null and jyzbLedger.voucherTimeTo != ''">
     and VOUCHER_TIME <![CDATA[>= ]]> TO_DATE(#{jyzbLedger.voucherTimeTo},'yyyy-MM-dd')
   </if>
   <if test="jyzbLedger.voucherTimeFrom != null and jyzbLedger.voucherTimeFrom != ''">
      and VOUCHER_TIME <![CDATA[<= ]]> TO_DATE(#{jyzbLedger.voucherTimeFrom},'yyyy-MM-dd')
   </if>

correct way to write
First try TO_CHAR to convert the date into a yyyy-MM-dd format string, and then use TO_DATE to convert it into a date.

  <if test="jyzbLedger.voucherTimeTo != null and jyzbLedger.voucherTimeTo != ''">
     and TO_DATE( TO_CHAR( VOUCHER_TIME, 'yyyy-MM-dd' ), 'yyyy-MM-dd' ) <![CDATA[>= ]]> TO_DATE(#{jyzbLedger.voucherTimeTo},'yyyy-MM-dd')
   </if>
   <if test="jyzbLedger.voucherTimeFrom != null and jyzbLedger.voucherTimeFrom != ''">
      and TO_DATE( TO_CHAR( VOUCHER_TIME, 'yyyy-MM-dd' ), 'yyyy-MM-dd' ) <![CDATA[<= ]]> TO_DATE(#{jyzbLedger.voucherTimeFrom},'yyyy-MM-dd')
   </if>

Time range query in MybatisPlus

 queryWrapper
   .apply(ObjectUtils.isNotEmpty(jyzbLedger.getVoucherTimeTo()),
     "TO_DATE( TO_CHAR( VOUCHER_TIME, 'yyyy-MM-dd' ), 'yyyy-MM-dd' ) >= TO_DATE ({0},'yyyy-MM-dd')", jyzbLedger.getVoucherTimeTo())
   .apply(ObjectUtils.isNotEmpty(jyzbLedger.getVoucherTimeFrom()),
     "TO_DATE( TO_CHAR( VOUCHER_TIME, 'yyyy-MM-dd' ), 'yyyy-MM-dd' ) <= TO_DATE ({0},'yyyy-MM-dd')", jyzbLedger.getVoucherTimeFrom());

TO_DATE( TO_CHAR( VOUCHER_TIME, ‘yyyy-MM-dd’ ), ‘yyyy-MM-dd’ )

2. The input parameter is time data of Date type.

Date类型To receive parameters, you need to fix the parameter transfer format with the front end yyyy-MM-dd, and then use it @DateTimeFormat格式化. If you do not use @DateTimeFormat and then use the Date type to receive parameters, an error will be reported !

TO_CHAR Convert date or number to string

Use the TO_CHAR function to convert the input date format into a specified format string, and convert the query parameters into a specified format string.

<!-- voucherTimeTo为Date类型时不能用 jyzbLedger.voucherTimeTo != '' 判空会报错的          -->
 <if test="jyzbLedger.voucherTimeTo != null ">
     and to_char(VOUCHER_TIME,'yyyy-MM-dd') <![CDATA[>= ]]> to_char(#{jyzbLedger.voucherTimeTo},'yyyy-MM-dd')
 </if>
 <if test="jyzbLedger.voucherTimeFrom != null ">
      and to_char(VOUCHER_TIME,'yyyy-MM-dd') <![CDATA[<= ]]> to_char(#{jyzbLedger.voucherTimeFrom},'yyyy-MM-dd')
 </if>

date_format formats Date type parameters into the specified type of time

   <if test="oppConditionVO.achievementDateStart != null and oppConditionVO.achievementDateStartEnd != null">
     and date_format( achievement_date, '%Y-%m-%d' )
      BETWEEN date_format( #{oppConditionVO.achievementDateStart}, '%Y-%m-%d' )
