As a database programmer sometime you may get values of day, month and year in integer format. You may need to use these values to generate a date in date datatype. For this purpose you can use the built-in functionDATEFROMPARTS. This function was introduced in SQL Server 2012. This f...
SQL DECLARE @StartDate AS DATE DECLARE @EndDate AS DATE DECLARE @CurrentDate AS DATE SET @StartDate = CONVERT(DATE,'01/01/2020',103) SET @EndDate = CONVERT(DATE,'04/01/2021',103) SET @CurrentDate = @StartDate CREATE TABLE #Date ([Date] VARCHAR(20)) WHILE (@Current...
select year(createtime) from life_unite_product --取时间字段的年值 select datepart(yy,createtime) from life_unite_product --取时间字段的年值 select datepart(qq,createtime) from life_unite_product --取时间字段的季度值 select datepart(mm,createtime) from life_unite_product --取时间字段的月值 ...
Year(CreatedDate), Month(CreatedDate) orderby Yeardesc,Monthdesc 然后我希望在Entity Framework里实现,我用Entity SQL实现了下。 select Year, Month, Count(it.PostId)asCount from Entities.Postasit groupby Year(it.CreatedDate)asYear, Month(it.CreatedDate)asMonth ...

```sql SELECT YEAR_MONTH(date_column) AS year_month, COUNT(*) AS count FROM table_name GROUP BY year_month; ``` 这样就可以得到一个每个月份对应的数据量统计结果,方便进行后续的数据分析和可视化操作。 需要注意的是,使用year_month函数时要确保传入的参数是一个合法的日期或日期时间表达式,否则可能会...
- SELECT year(current_date); 2.获取一些日期的天数、月份和年份: - SELECT day('2024-09-01'); - SELECT month('2024-09-01'); - SELECT year('2024-09-01'); 3.对日期字段进行筛选: - SELECT * FROM table WHERE day(date_column) = 1; - SELECT * FROM table WHERE month(date_column) ...
If you need a complete list of month-year as well as dates between two datetimes in SQL, you can use the scripts below. DATE list between two datetimes(including both the dates): DECLARE @startDate DATE = '2014-04-28', @endDate DATE = '2014-05-06' ; WITH CTE AS...
应该是想取得年月吧 select (cast(datepart(yy,时间栏位) as nvarchar(4))+'_'+cast(datepart(mm,时间栏位) as nvarchar(2))) as YEAR_MONTH from 表名
