这个例子执行时，将返回如下的结果：

 

site name                       day and month posted

………………………………………………………………………

yahoo                           friday - february

microsoft                       tuesday - june

magicw3                         monday - june

(3 row(s) affected)

 

返回日期和时间范围

当你分析表中的数据时，你也许希望取出某个特定时间的数据。你也许对特定的某一天中╠╠比如说2000年12月25日╠╠访问者在你站点上的活动感兴趣。要取出这种类型的数据，你也许会试图使用这样的select语句：

 

select * from weblog where entrydate=”12/25/20000”
