我正在尝试将当前年份以YYYY的形式与月份列中的monthy
结合起来。
monthy monthsname
------------------------
1 January
2 February
3 March
4 April
5 May
6 June
7 July
8 August
9 September
10 October
11 November
12 December
以下是我得到的输出:
monthy monthsname month_number
------------------------------------
5 May NULL
6 June NULL
8 August NULL
9 September NULL
10 October NULL
11 November NULL
1 January 201701
2 February 201702
3 March 201703
4 April 201704
7 July 201707
12 December 201712
而不是month_number为null,我试图这样做:
isnull(ss.month_number, cast(convert(varchar(4), DATEPART(year, getdate())) as int) + right('0-- ' + cast(convert(varchar(2), monthy) as int), 2))
我没有得到正确的输出:我希望201705
的第一行记录month_number
之类的东西
答案 0 :(得分:1)
根据您的数据类型,您可能希望转换它,但它只是年份* 100加上月份数,以获得您尝试创建的数字的整数表示。
ISNULL(month_number,YEAR(GETDATE())*100+monthy)
答案 1 :(得分:0)
你可以试试这个:
SELECT
CONVERT(VARCHAR(4),DATEPART(YEAR, GETDATE())) + --year
(
REPLICATE('0', 2 - LEN(CONVERT(VARCHAR(2), monthy)) ) +
CONVERT(VARCHAR(2), monthy) --monthy
)
