MySQL - 使用SUM无效使用组函数

Question

我收到错误消息'＃1111 - 无效使用群组功能'并带有以下查询，我不完全确定原因。

我最初将SUM的三个组件中的每一个都作为单独的视图（您可以在JOIN列表中看到该设置的残余），但由于无法使用索引而运行该视图花费的时间太长在加入视图。

SELECT 
    `VehicleClaim`.`id` AS `Vehicle_claim_id`, `VehicleClaim`.`Vehicle_registration_number`,
    `Claim`.`id` AS `claim_id`, `Claim`.`created` AS `claim_created`, DATE_FORMAT(`Claim`.`created`, '%b') AS `claim_created_month`,
    `ClaimSubtype`.`name` AS `claim_subtype`,
    `Vendor`.`name` as `vendor_name`,

    IF(`VehicleClaim`.`id` IS NOT NULL,
        IF(`VehicleClaimUpdate`.`id` IS NOT NULL, `VehicleClaimUpdateStatus`.`status`, `ClaimStatus`.`status`), 
        IF(`ClaimUpdate`.`id` IS NOT NULL, `ClaimUpdateStatus`.`status`, `ClaimStatus`.`status`)
    ) AS `status`,

    IF(`VehicleClaimUpdate`.`id` IS NOT NULL, `VehicleClaimUpdate`.`result`,
        IF(`ClaimUpdate`.`id` IS NOT NULL, `ClaimUpdate`.`result`, NULL)
    ) AS `result`,
