access和SqlServer 关于时间的SQL语句比较

1.1算出日期差：
1.access:       datediff('d',fixdate,getdate())

2.sqlserver:    datediff(day,fixdate,getdate())

ACCESS实例：    select * from table where data=datediff('d',fixdate,getdate())
sqlserver实例： select * from table where data=datediff(day,fixdate,getdate())
1.2算出时间差：
1.access:       datediff('h',fixdate,getdate())
2.sqlserver:    datediff(Hour,'2004-12-10',getdate())

ACCESS实例：    select DATEDIFF('h',HMD,getdate())
sqlserver实例： select datediff(Hour,'2004-12-10',getdate())

1.3算出月份差：
1.access:       datediff('m',fixdate,getdate())
2.sqlserver:    datediff(Month,'2004-12-10',getdate())

ACCESS实例：    select DATEDIFF('m',HMD,getdate())
sqlserver实例： select datediff(Month,'2004-12-10',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=0ACCESS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 ＝100ACCESS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()2.sqlserver:    getdate()
