这段代码缺少了一个逗号，导致在计数器 `@count` 加 1 的语句中出现了语法错误。具体位置在 `@count = @count+1,` 这行代码中，应该在语句末尾添加一个逗号。

修改后的代码如下：

create procedure catprofit As
/*定义游标ls*/
declare cp cursor for 	select Catmoney,Catsell from Cat where Catstate='已售';
/*定义变量*/
declare @count int = 0,
	@money int =0, 
	@sell int = 0, 
	@profit1 int =0, 
	@profit2 int =0; 
begin 
	open cp; 
	fetch next from cp into @money,@sell; 
	while @@fetch_status=0 
	begin 
		@count = @count+1, 
		@profit1=@sell-@money, 
		@profit2=@profit1+@profit2, 
		fetch cp into @money,@sell; 
	end  
	/*print @p+convert(varchar,@q)其中@p是字符串类型，@q是数值类型*/
	print '猫咪销量:'+convert(varchar,@count); 
	print '总利润:'+convert(varchar,@profit2); 
	close cp; 
end;

修改后的代码已经不会报错了，可以正常编译和执行。
