mybatis if 判断，指点这样写正确吗

select t.*,x.mc from whxj_base t left join xjzt x on t.sslx = x.id where 1=1
and to_char(t.xjksrq,'yyyy') = #{0}


and to_char(t.xjksrq,'MM') = #{1}

我的if判断代码呢 ？ 谁给我屏蔽了？？？test = "#{1}!=null and #{1} !=''“

select t.*,x.mc from whxj_base t left join xjzt x on t.sslx = x.id
where 1=1

and to_char(t.xjksrq,'yyyy') = #{0}


and to_char(t.xjksrq,'MM') = #{1}
请指点？？？？？

<select id="count" parameterType="Roles" resultType="int">
    select count(0) from role
    <where>
        <if test="name != null and name != ''">
            name like '%${name}%'
        </if>
    </where>
</select>
