高手,帮我指导、优化一下我的这2个SP!服务器总是卡...
我们服务器每天都会有一段时间比较卡,从活动监视器看有200个进程,大部分都是“可运行”、“已挂起”,这是不是跟我的存储过程写法有关。请高手们指导我一下,帮我优化一下看看。谢谢。


花点时间和精力帮我看下吧。谢谢

另外,我想问问看,如果启用事务,会不会减少服务器运行SP时消耗的资源??SP1:
C# code




alter proc [dbo].[sp_bad]
(    
    @d varchar(5),
    @p varchar(50),
    @im varchar(20)
)
as
begin
    
    declare @c int,@time1 datetime,@end int
    declare @pros varchar(200)
    set @pros=',aaa,bbb,ccc,ddd,eee,fff,'
    set @c=0
    select top 1 @c=cc,@time1=time1 from t_badToday where im=@im
    if @c=0
    begin
        insert into t_badToday(d,p,im) values(@d,@p,@im)
        if charindex(','+@p+',',@pros)>0
            exec [sp_yun] @d,@p,@im,'','1'    --调用另一SP
        else
            select 0
        return
    end
    else
    begin
        if @c>5
        begin
            select 1
            return
        end
        else
        begin
            update t_badToday set cc=cc+1 where im=@im
            if datediff(d,@time1,getdate())=0
            begin
                select 0
                return 
            end
            else
            begin
                if charindex(','+@p+',',@pros)>0
                    exec [sp_yun] @d,@p,@im,'','1'    --调用另一SP
                else
                    select 0
                return    
            end
        end
