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 tabl

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()
