mybatis在where中比較復雜的判斷

        <if test="param.applicationStateInNumber != null and param.applicationStateInNumber != ''">
            and  #{param.applicationStateInNumber,jdbcType=INTEGER} like (case when (fa.whether_invoice is null  and fa.whether_pay is null ) then "1"
            when  (fa. whether_invoice=1 and fa.whether_pay is null ) then  "2、3"
            when (fa.whether_invoice = 1 and fa.whether_pay  = 1) then "4" end)
        </if>

這個是需要判斷傳入的參數不為空，且傳入的參數在一個case when 中，起初把

#{param.applicationStateInNumber,jdbcType=INTEGER}

寫成了

param.applicationStateInNumber

報錯：badsqlGrammer，未知的參數param.applicationStateInNumber

#{param.applicationStateInNumber,jdbcType=INTEGER}
