WHERE fname LIKE concat('%',#{fname},'%')

<select id="getTotalCount" parameterType="map" resultType="int">
	SELECT count(*) FROM food
	<include refid="wheres" />
</select>

<resultMap type="Food" id="foodMap">
	<id property="fid" column="fid" />
	<result property="fname" column="fname" />
	<result property="ftype" column="ftype" />

</resultMap>

<select id="getFoods" parameterType="map" resultMap="foodMap">
