具体的网址倒是没保存，可是我这个人习惯把好的代码记起方法保存下来，现在贴出来，希望原作者体谅。
<div class=”codetitle”><a style=”CURSOR: pointer” data=”83550″ class=”copybut” id=”copybut83550″ onclick=”doCopy(‘code83550’)”> 代码如下:<div class=”codebody” id=”code83550″>
—上个月月初第一天
select CONVERT(varchar(12),DATEADD(mm,DATEDIFF(mm,dateadd(mm,-1,getdate())),0),112 )
—上个月月末最后一天
select CONVERT(varchar(12),dateadd(ms,-3,DATEDIFF(m,getdate()),0)),112 )
–1. 显示本月第一天
SELECT DATEADD(mm,0)
select convert(datetime,convert(varchar(8),getdate(),120)+’01’,120)
–2. 显示本月最后一天
select dateadd(day,convert(datetime,dateadd(month,1,120))
SELECT dateadd(ms,getdate())+1,0))
–3. 上个月的最后一天
SELECT dateadd(ms,0))
–4. 本月的第一个星期一
select DATEADD(wk,DATEDIFF(wk,dateadd(dd,6-datepart(day,0)
–5. 本年的第一天
SELECT DATEADD(yy,DATEDIFF(yy,0)
–6. 本年的最后一天
SELECT dateadd(ms,DATEADD(yy,0))
–7. 去年的最后一天
SELECT dateadd(ms,0))
–8. 本季度的第一天
SELECT DATEADD(qq,DATEDIFF(qq,0)
–9. 本周的星期一
SELECT DATEADD(wk,0)
–10. 查询本月的记录
select from tableName where DATEPART(mm,theDate)=DATEPART(mm,GETDATE()) and DATEPART(yy,theDate) = DATEPART(yy,GETDATE())
–11. 查询本周的记录
select from tableName where DATEPART(wk,theDate) = DATEPART(wk,GETDATE())
–12 查询本季的记录 注：其中:GETDATE() 是获得系统时间的函数。
select * from tableName where DATEPART(qq,theDate) = DATEPART(qq,GETDATE())
–13. 获取当月总天数:
select DATEDIFF(dd,getdate()))
select datediff(day,datediff(mm,”,”),’1900-02-01′))
–14. 获取当前为星期几
SELECT DATENAME(weekday,getdate())
