How SQL SERVER 2000 obtains the current system time with SQL statements
is to use GETDATE ();
getdate in SQL ()
A very powerful date format function in SQL Server
Select CONVERT (varchar), GETDATE (), 0): 2008 10:57am Select CONVERT (varchar), GETDATE (), 1): 05/16/08 Selec T CONVERT (varchar), GETDATE (), 2): 08.05.16 select CONVERT (varchar), GETDATE ()
Sometimes use JS to get the server time. Usually use System.DateTime
The method is as follows:
Copy Code code as follows:
There's another way: Using JavaScript's "runat=" server attribute
