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()
