Sql server 未来12个月的日期格式查询

我正在尝试查询日期格式YYYYMM。我现在的问题是这个

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

我想得到的是从当前日期到未来12个月的YYYYMM日期格式。但我目前的查询是：201705201706，…201711201712201713201714，等等。现在你可能已经知道我想要的是：201705201706，…201711201712201801201802，等等

我搜索了几乎所有的网页，但没有找到答案。所以我来到这里，希望有人能帮助我

提前谢谢

您可以使用SQL Server的DATEADD，它将处理滚动到下一年并重置回1月份的问题，然后将其转换为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：

+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+--------+
| 201705 | 201706 | 201707 | 201708 | 201709 | 201710 | 201711 | 201712 | 201801 | 201802 | 201803 | 201804 | 201805 |

方便的小片段，因为我永远记不起代码
