Date format statement when SqlServer query
The default date field datetime format for SQL Server Chinese is y-mm-dd Thh:mm:ss.mmm
For example:
select getdate() 2004-09-12 11:06:08.177
SQL Server may be used to convert the date format:
Examples are as follows:
select CONVERT(varchar, getdate(), 120 ) 2004-09-12 11:06:08 select replace(replace(replace(CONVERT(varchar, getdate(), 120 ),'-',''),' ',''),':','') 20040912110608 select CONVERT(varchar(12) , getdate(), 111 ) 2004/09/12 select CONVERT(varchar(12) , getdate(), 112 ) 20040912 select CONVERT(varchar(12) , getdate(), 102 ) 2004.09.12 select CONVERT(varchar(12) , getdate(), 101 ) 09/12/2004 select CONVERT(varchar(12) , getdate(), 103 ) 12/09/2004 select CONVERT(varchar(12) , getdate(), 104 ) 12.09.2004 select CONVERT(varchar(12) , getdate(), 105 ) 12-09-2004 select CONVERT(varchar(12) , getdate(), 106 ) 12 09 2004 select CONVERT(varchar(12) , getdate(), 107 ) 09 12, 2004 select CONVERT(varchar(12) , getdate(), 108 ) 11:06:08 select CONVERT(varchar(12) , getdate(), 109 ) 09 12 2004 1 select CONVERT(varchar(12) , getdate(), 110 ) 09-12-2004 select CONVERT(varchar(12) , getdate(), 113 ) 12 09 2004 1 select CONVERT(varchar(12) , getdate(), 114 ) 11:06:08.177

Commonly used:
Select CONVERT(varchar(100), GETDATE(), 24): 10:57:47Select CONVERT(varchar(100), GETDATE(), 108): 10:57:49Select CONVERT(varchar(100), GETDATE(), 12): 060516Select CONVERT(varchar(100), GETDATE(), 23): 2006-05-16select CONVERT(varchar(12) , getdate(), 112 ) : 20040912 Select CONVERT(varchar(100), GETDATE(), 8): 10:57:46
For example:
convert(varchar(100),a.makedate,120) as makedate
PS: The following introduces Sql Server about date query, if the date in the table to a specific time
1. If the query date parameter is '2017/02/21', and the field in the database table is'2017/02/21 12:34: 16.963', you need to format the date to query it, as follows
select * from table t where t.date between CONVERT(datetime, '2017/02/21', 120) and CONVERT(datetime, '2017/02/21', 120)+' 23:59:59') ;
The query range is '2017/02/21 00:00:00'~'2017/02/21 23:59: 59', which will solve the problem.
2. Or use the dateadd method to add 1 day to the date, as follows
select * from table t where t.date >= CONVERT(datetime, '2017/02/21') and t.date < CONVERT(datetime, dateadd(day,1,'2017/02/21'));
The scope of the query is '2017/02/21'
