解释一下代码
Sql="select top 10 artid,arttitle,cast(year(builddate) as nvarchar(4))+'-'+cast(month(builddate) as nvarchar(2))+'-'+cast(day(builddate) as nvarchar(2)), hits from pub_article where arttype="&TempArray(0,i)&" and boardid="&PUB_GFGS_ID&" order by builddate desc"帮我解释一哈代码
cast(year(builddate) as nvarchar(4))+'-'+cast(month(builddate) as nvarchar(2))+'-'+cast(day(builddate) as nvarchar(2)),
这一点就行了啊
