If a comment SQL fragment exists in the SQL code, the #{} parameter cannot be used in the comment SQL fragment. As follows:

        on t1.dealer_code = t4.dealer_code
        -- left join (
        --     select
        --         ads_code
        --        ,sum(case when car like '%MM%' or model = 'MM' then ss_num else 0 end) as ws_MM_num
        --     from abc_assss_ss
        --     where seq = 1 and count_date between '2021-04-01' and '2021-06-30'
        --     group by
        --         dealer_code
        --     )t2
        -- on t1.asd_code = t2.ads_code
        )
        select

      If you replace the between and with the parameter between #{start_time} and #{end_time}, it will report this error, hope it can solve your problem
