<select id="selectXXX" parameterType="Map" resultMap="XXXXResultMap">
		SELECT 
			XXX,XXX			
		FROM TB_XXX 
		<where>
		    <if test="id != null and id != ''">
		    	AND ID = #{id}

		    <if test="account != null and account != ''">
		    	AND ACCOUNT = #{account}
		    </if>
		    <if test="state != null and state != '' and state.code != null and state.code != ''">
		    	AND STATE = #{state.code}
		    </if>
	    </where>
	    <order>
	    	<if test=" sortWay != null and sortWay == 'llpx'">
		    	ORDER BY FORMAT ASC

		    <if test=" sortWay != null and sortWay == 'btypx'">
		    	ORDER BY BID DESC
