Mybatis的直接执行SQL

mybatis直接执行SQL实际就是在mapper里面加个String

mapper.xml

<select id="selectBySql" parameterType="String">
${value}
</select>

对于同结构的表可以统一处理

 <insert id="insertTraject" parameterType="com.piccapp.dto.entity.TrajectoryData">
    insert into ${tablename} (ID, C_SYS_R_TIME, CREATECODE, 
      SYSTEMCODE, INTERFACENAME, CONTENTTYPE, 
      INPUTTIME, CONTENTTEXT)
      values (${tablename}_sequence.nextval, #{cSysRTime,jdbcType=VARCHAR}, #{createCode,jdbcType=VARCHAR}, 
      #{systemCode,jdbcType=VARCHAR}, #{interfaceName,jdbcType=VARCHAR}, #{contenttype,jdbcType=VARCHAR}, 
      #{inputtime,jdbcType=TIMESTAMP}, #{param,jdbcType=BLOB})
  </insert>

tablename在实体TrajectoryData里面
