access date sqlserver date time Compare

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()

What are the benefits of multithreading in c#? What are the benefits of multithreading in c#? Apr 03, 2025 pm 02:51 PM

The advantage of multithreading is that it can improve performance and resource utilization, especially for processing large amounts of data or performing time-consuming operations. It allows multiple tasks to be performed simultaneously, improving efficiency. However, too many threads can lead to performance degradation, so you need to carefully select the number of threads based on the number of CPU cores and task characteristics. In addition, multi-threaded programming involves challenges such as deadlock and race conditions, which need to be solved using synchronization mechanisms, and requires solid knowledge of concurrent programming, weighing the pros and cons and using them with caution.
