实现两个表连接并将数据并写入到一张临时表中

ALTER PROCEDURE [dbo].[BlogPhotoClass_Select]

    select @f = count(*) from Blogphoto where Username = @Username and Classid = 0
    
    --如果有图片就把第一张图片做相册封面
    if(@f > 0)
    BEGIN
        select top 1 @Mainpic = SPath from Blogphoto where Username = @Username and Classid = 0 order by id
    END
    
    --创建一个临时分类表@temptable，比数据库中的分类表多一个图片数量字段

    insert into @temptable (ID,Username,Classname,[Datetime],Password,MainPic,PhotoCount) values (0,@Username,'默认相册',getdate(),null,@MainPic,@f)
