access与SqlServer 之时间与日期及其它SQL语句比较

1、Datediff：

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=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()

2.sqlserver:    getdate()

ACCESS实例：    select   now()

sqlserver实例： select getdate()
