mybatis的mapper文件中，sql插入語句

sql語句沒有對字段判斷

    <insert id="insert">
		insert into student (
			id, 
			name, 
			age,
			money, 
			cla_code,
			create_time,
			del_flag
		)values (
			#{id,jdbcType=INTEGER},
			#{name,jdbcType=VARCHAR},
			#{age,jdbcType=INTEGER},
			#{money,jdbcType=DECIMAL}, #{cla_code,jdbcType=VARCHAR},
			#{create_time,jdbcType=TIMESTAMP},
			#{del_flag,jdbcType=CHAR}
		)
	</insert>

sql語句對字段判斷

	<insert id="insertSelective" parameterType="com.itunion.Student">
	    insert into student
	    <trim prefix="(" suffix=")" suffixOverrides=",">
	      <if test="id != null">
	        id,
