【SqlServer】SqlServer常用日期操作

1. 简单查询

说明	查询 sql
日期格式化	SELECT CONVERT(VARCHAR, GETDATE(), 102) AS '102', -- yyyy.mm.dd CONVERT(VARCHAR, GETDATE(), 108) AS '108', -- hh:mi:ss CONVERT(VARCHAR, GETDATE(), 111) AS '111', -- yyyy/mm/dd CONVERT(VARCHAR, GETDATE(), 112) AS '112', -- yyyymmdd CONVERT(VARCHAR, GETDATE(), 23) AS '23', -- yyyy-mm-dd left(CONVERT(VARCHAR, GETDATE(), 23),7) as 'yyyy-mm', -- yyyy-mm CONVERT(VARCHAR, GETDATE(), 120) AS '120', -- yyyy-mm-dd hh:mi:ss CONVERT(VARCHAR, GETDATE(), 121) AS '121' -- yyyy-mm-dd hh:mi:ss.mmm
本月第一天	SELECT DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0) ;
本月最后一天	SELECT DATEADD(DAY, -1, DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE()), 0)); 或者：select EOMONTH(GETDATE());

2. 查询两个日期范围内所有日期列表

WITH xrange AS (
    SELECT CAST('2025-07-01' AS DATE) AS curr_day
    UNION ALL
    SELECT DATEADD(DAY, 1, curr_day)
    FROM xrange
    WHERE DATEADD(DAY, 1, curr_day) <= CAST('2025-09-10' AS DATE)
)
SELECT curr_day
FROM xrange
OPTION (MAXRECURSION 0);

3. 查询两个月份范围内所有月份列表

WITH xrange AS (
    SELECT CAST(concat('2025-07','-01') AS DATE) AS curr_month
    UNION ALL
    SELECT DATEADD(month, 1, curr_month)
    FROM xrange
    WHERE DATEADD(month, 1, curr_month) <= CAST(concat('2025-09','-10') AS DATE)
)
SELECT left(curr_month,7) as curr_month
FROM xrange
OPTION (MAXRECURSION 0);
