我有一个SQL查询,该查询已经使用IF()函数根据返回的各个表达式检查某些条件。我必须在IF()中添加另一个条件(这将是另一个“和”),这将影响两个表达式的属性。查询是
select
#{booking_variable}.travel_id as operator_id,
round(sum(#{ticket_variable}.customer_commission), 2) as commission,
IF(
(#{booking_variable}.is_online = #{AdminType::YES}
and #{booking_variable}.is_ts_payment = #{AdminType::YES}),
round(sum(-#{ticket_variable}.customer_commission
- #{ticket_variable}.convenience_charge_amount
+ #{ticket_variable}.our_convenience_charge_amount), 2),
round(sum(#{ticket_variable}.adult_fare
- #{ticket_variable}.customer_commission
+ #{ticket_variable}.service_tax_amount
+ #{ticket_variable}.our_convenience_charge_amount
- #{ticket_variable}.offer_discount), 2)
) as amount_to_be_paid,
round(sum(#{booking_variable}.total_fare)) as total_fare,
0 as cancel_fare,
round(sum(#{ticket_variable}.adult_fare
+ #{ticket_variable}.service_tax_amount
- #{ticket_variable}.offer_discount )) as net_amount,
#{booking_variable}.travel_name as operator_name,
ROUND(sum(#{ticket_variable}.service_tax_amount), 2) as total_service_tax,
ROUND(sum(#{ticket_variable}.convenience_charge_amount), 2) as total_convenience_charge_amount,
ROUND(sum(#{ticket_variable}.our_convenience_charge_amount), 2) as total_our_convenience_charge_amount,
0 as cancelled_convenience_charge_amount,
(select users.branch_id from users where id=#{ticket_variable}.booked_by) as travel_branch_id
from #{booking_variable} use index(index_#{booking_variable}_travel_date),
#{ticket_variable}
where #{conditions1[0]}
group by travel_branch_id, operator_id
在这里,在IF()表达式中,我必须检查另一个变量的value。如果该值为true,则查询应按原样运行,如果不正确,则应将#{ticket_variable}.convenience_charge_amount + #{ticket_variable}.our_convenience_charge_amount
and的值#{ticket_variable}.our_convenience_charge_amount
视为0。感谢任何帮助。
您可以嵌套IF()
表达式。
如果您需要部分计算是有条件的,则可以使用IF()
。
...
IF(
(#{booking_variable}.is_online = #{AdminType::YES}
and #{booking_variable}.is_ts_payment = #{AdminType::YES}),
round(sum(-#{ticket_variable}.customer_commission
- IF((...some other condition...),
#{ticket_variable}.convenience_charge_amount
+ #{ticket_variable}.our_convenience_charge_amount,
0)
), 2),
...
