SQL模糊查询 ---- 编号和名字(模糊查询)

1.背景

使用编号和名字查询数据,其中名字为模糊查询.

2.解决方案

  <select id="selectAccordingTotheNumberandname" parameterType="java.util.Map" resultMap="DegreeBaseResultMap">
    SELECT
    pd.tuid,pd.donation_logo,pd.donation_degree,pd.donation_code,pd.slogan,
    pd.create_by,pd.owner_id,pd.created,pd.updated,pd.delete_flag,pd.delete_by,pd.donation_num,
    pd.donation_name,pd.start_age,pd.end_age,pd.join_type,pd.fruit_balance,pdd.ren_num
    FROM pm_donation pd
    LEFT JOIN
    pm_donation_degree pdd
    ON
    pd.donation_degree = pdd.degree
    WHERE
    delete_flag = #{deleteFlag}
    <if test="donationMessage != null">
    AND
    (
    donation_code = #{donationMessage}
    OR
     LOCATE(#{donationMessage},donation_name)>0
     )
    </if>
  </select>

最后一个AND连接的( donation_code = #{donationMessage} OR LOCATE(#{donationMessage}, donation_name)>0)
