未来12个月的日期格式查询
Date format query for next 12 months
我正在尝试查询有关日期格式 YYYYMM 的问题。我当前的查询是这个。
declare @M0 nvarchar(6);set @M0=(SELECT CONVERT(nvarchar(6), GETDATE(), 112))
declare @M1 nvarchar(6);set @M1=@M0+1;
declare @M2 nvarchar(6);set @M2=@M1+1;
declare @M3 nvarchar(6);set @M3=@M2+1;
declare @M4 nvarchar(6);set @M4=@M3+1;
declare @M5 nvarchar(6);set @M5=@M4+1;
declare @M6 nvarchar(6);set @M6=@M5+1;
declare @M7 nvarchar(6);set @M7=@M6+1;
declare @M8 nvarchar(6);set @M8=@M7+1;
declare @M9 nvarchar(6);set @M9=@M8+1;
declare @M10 nvarchar(6);set @M10=@M9+1;
declare @M11 nvarchar(6);set @M11=@M10+1;
declare @M12 nvarchar(6);set @M12=@M11+1;
select @M0,@M1,@M2,@M3,@M4,@M5,@M6,@M7,@M8,@M9,@M10,@M11,@M12
我要获取的是从当前日期开始的接下来 12 个月的 YYYYMM 日期格式。但是我当前的查询是:201705,201706,...201711,201712,201713,201714,等等。所以现在你可能已经知道我想要得到的是:201705,201706,...201711,201712,201801,201802,等等。
我几乎搜索了整个网络,但没有找到答案。所以我来到这里希望有人能帮助我。
提前致谢!
您可以使用 SQL 服务器的 DATEADD
,它将处理滚动到下一年并重置回一月,然后将其转换为您的 YYYYMM 格式,如下所示:
DECLARE @M0 NVARCHAR(6) = CONVERT( NVARCHAR(6), GETDATE(), 112 );
DECLARE @M1 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 1, GETDATE() ), 112 );
DECLARE @M2 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 2, GETDATE() ), 112 );
DECLARE @M3 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 3, GETDATE() ), 112 );
DECLARE @M4 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 4, GETDATE() ), 112 );
DECLARE @M5 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 5, GETDATE() ), 112 );
DECLARE @M6 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 6, GETDATE() ), 112 );
DECLARE @M7 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 7, GETDATE() ), 112 );
DECLARE @M8 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 8, GETDATE() ), 112 );
DECLARE @M9 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 9, GETDATE() ), 112 );
DECLARE @M10 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 10, GETDATE() ), 112 );
DECLARE @M11 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 11, GETDATE() ), 112 );
DECLARE @M12 NVARCHAR(6) = CONVERT( NVARCHAR(6), DATEADD( MONTH, 12, GETDATE() ), 112 );
SELECT @M0, @M1, @M2, @M3, @M4, @M5, @M6, @M7, @M8, @M9, @M10, @M11, @M12
输出为:
+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+
