這里如何避免零除錯誤？

Question

我遇到的以下查詢遇到除以0錯誤：

select  pp.building_name, 
        ld.tenant_trading_name,  
        tenancy_reference,  
        ld.turnover_threshold, 
        ld.percentage_rent, 
        ld.income_base_rent_ach, 
        ld.income_base_rent_ach / ld.percentage_rent as correct 
from 
    lease_deal.lease ld

inner join property.property pp
    on ld.building_id = pp.building_id

where 
    (ld.income_base_rent_ach / ld.percentage_rent ) <> ld.turnover_threshold
    and lease_status = 'APPROVED'
    and ld.progenesis_load_date is  null
order by pp.building_name

我試圖通過執行以下操作來糾正此問題 - 但我收到語法錯誤，我不確定為什么？ 這里的語法不正確是什么？

select  pp.building_name, 
        ld.tenant_trading_name,  
        tenancy_reference,  
        ld.turnover_threshold, 
        ld.percentage_rent, 
        ld.income_base_rent_ach, 
        ld.income_base_rent_ach / ld.percentage_rent as correct 
from 
    lease_deal.lease ld

inner join property.property pp
    on ld.building_id = pp.building_id

where 
    case when ld.percentage_rent = 0
    then 1=1
    else ((ld.income_base_rent_ach / ld.percentage_rent ) <> ld.turnover_threshold)
    end
    and lease_status = 'APPROVED'
    and ld.progenesis_load_date is  null
order by pp.building_name

如何更換

(ld.income_base_rent_ach / ld.percentage_rent ) <> ld.turnover_threshold

同

ld.income_base_rent_ach <> (ld.percentage_rent * ld.turnover_threshold)
