更新所有其他記錄

Question

我有一個查詢下面。我想添加一個條件，如果參數@IsPrestigeFeatured = 0然後更新IsprestigeFeatured列中的所有其他行<>PropertyId爲0，並且如果@IsPrestigeFeatured = 1然後IsprestigeFeatured = 1 where propertyId = PropertyId。

我查看了case語句/ if語句，但我似乎無法獲得正確的語法。 歡呼

ALTER PROCEDURE dbo.Update_Property 
@propertyId int, 
@propertyTypeId int, 
@Name ntext, 
@Price int, 
@DescriptionResultsExcerpt text, 
@Description ntext, 
@Characteristics ntext, 
@IsRenovation int, 
@IsCharacter int, 
@IsPrestige int, 
@IsHomepageFeatured int, 
@IsPrestigeFeatured int, 
@CityId int, 
@DepartmentId int, 
@CommuneId int 

As 
UPDATE  Property 
SET  Name = @Name, PropertyTypeID = @propertyTypeId, Price = @Price, 
      DescriptionResultsExcerpt = @DescriptionResultsExcerpt, 
      Description = @Description, Characteristics = @Characteristics, 
      IsRenovation = @IsRenovation, IsCharacter = @IsCharacter, 
      IsPrestige = @IsPrestige, IsHomepageFeatured = @IsHomepageFeatured, 
      IsPrestigeFeatured = @IsPrestigeFeatured, CityId = @CityId, 
      DepartmentId = @DepartmentId, CommuneId = @CommuneId 

FROM Property 
WHERE (PropertyId = @PropertyId)
