mybatis if 判断，指点这样写正确吗

Question

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} !=''“

Answer 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？？？？？
