access与SqlServer 之SQL语句比较

1.1算出日期差：
1.access:??????? datediff('d',fixdate,getdate())
2.sqlserver:???? datediff(day,getdate())
ACCESS实例：???? select * from table where data=datediff('d',getdate())
sqlserver实例： select * from table where data=datediff(day,getdate())

1.2算出时间差：
1.access:??????? datediff('h',getdate())
2.sqlserver:???? datediff(Hour,'2004-12-10',getdate())
ACCESS实例：???? select DATEDIFF('h',HMD,getdate())
sqlserver实例： select datediff(Hour,getdate())

1.3算出月份差：
1.access:??????? datediff('m',getdate())
2.sqlserver:???? datediff(Month,getdate())
ACCESS实例：???? select DATEDIFF('m',getdate())
sqlserver实例： select datediff(Month,getdate())
----------------------------------------------------------------------------

2、日期变量
1.access:??????? #"&data&"#
2.sqlserver:???? '"&data&"'
ACCESS实例：???? select * from table where data=#"&data&"#
sqlserver实例： select * from table where data='"&data&"'
----------------------------------------------------------------------------

3、是否
1.access:??????? not finished
2.sqlserver:???? finished=0
ACCESS实例：???? select * from table where not finished
sqlserver实例： select * from table where finished=0
----------------------------------------------------------------------------

4、求余数

1.access:??????? a mod b＝100
2.sqlserver:???? a?? % b?? ＝100
ACCESS实例：???? select??? a mod b＝100 from table where not finished
sqlserver实例： select a?? % b?? ＝100?? from table where finished=0
----------------------------------------------------------------------------

5、获取当天日期1.access:??????? now()????? //date()是日期 time()是时间 date()&"? "&time()=now()2.sqlserver:???? getdate()ACCESS实例：???? select??? now()sqlserver实例： select getdate()?
