mysql限制无法针对1个id处理多条记录

Mysql过程针对1个id提供了三条记录。我试图针对1个id只获取1条记录。在哪里设置限制，以针对1个id只访问1条记录

创建定义者=

如果需要行，可以将限制1添加到YRU查询中

 SELECT 
     `zp`.`PlaceId`,
     `zp`.`PlaceName`,
     `zp`.`PlaceCategoryCode`,
     `zp`.`Description`,
     `zp`.`CompanyId_FK`,
     `zp`.`OwnerCompanyId_FK`,
     `zp`.`IsDeleted`,
     `zp`.`IsArchived`,
     `zp`.`CreatedDate`,
     `zp`.`ModifiedDate`,
     `zp`.`CreatedBy_FK`,
     `zp`.`ModifiedBy_FK`,
     (SELECT COUNT(`ApplianceId`) FROM `ZThinQ_Appliance` WHERE `ApplianceActionCode` = 1 AND `PlaceId_FK` = `PlaceId`)  AS activeDevices ,
     (SELECT COUNT(`ApplianceId`) FROM `ZThinQ_Appliance` where  `PlaceId_FK` = `PlaceId` ) AS totalDevices

    FROM `ZThinQ_Place` AS `zp` 
    JOIN `ZThinQ_Appliance` as `za`

    #ON `ZThinQ_Appliance`
    #ON `PlaceId` = `PlaceId_FK` 

    Where `zp`.`CompanyId_FK`=pCompanyId
    LIMIT 1

我有一个id的多个记录。所以我在我的过程中使用select distinct。就是这样

SELECT distinct
 `zp`.`PlaceId`,
 `zp`.`PlaceName`,
 `zp`.`PlaceCategoryCode`,
 `zp`.`Description`,
 `zp`.`CompanyId_FK`,
 `zp`.`OwnerCompanyId_FK`,
 `zp`.`IsDeleted`,
 `zp`.`IsArchived`,
 `zp`.`CreatedDate`,
 `zp`.`ModifiedDate`,
 `zp`.`CreatedBy_FK`,
 `zp`.`ModifiedBy_FK`,
 (SELECT COUNT(`ApplianceId`) FROM `ZThinQ_Appliance` WHERE `ApplianceActionCode` = 1 AND `PlaceId_FK` = `PlaceId`)  AS activeDevices ,
 (SELECT COUNT(`ApplianceId`) FROM `ZThinQ_Appliance` where  `PlaceId_FK` = `PlaceId` ) AS totalDevices

FROM `ZThinQ_Place` AS `zp` 
JOIN `ZThinQ_Appliance` as `za`

#ON `ZThinQ_Appliance`
#ON `PlaceId` = `PlaceId_FK` 

Where `zp`.`CompanyId_FK`=pCompanyId
LIMIT 1
