我最近在SSRS-2008标签中回复to this question,要求将日期中的日期号码更改为序号(即“1st”,“2nd”而不是“1”,“2”)。该解决方案涉及VB.Net功能。我很好奇如何在SQL中执行此任务(特别是t-sql和SQL Server),或者是否有一些内置支持。
所以这是一个场景:假设您已经为1000名参赛者组织了一个足球赛,并将结果放在一个包含名称和地点(正常数字)列的表格中。您希望创建一个查询,以查看序号中的用户名和位置。

这是一个适用于任何数字的可扩展解决方案。我认为其他人使用%100代表11,12,13,但我错了。
WITH CTE_Numbers
AS
(
SELECT 1 num
UNION ALL
SELECT num + 1
FROM CTE_Numbers
WHERE num < 1000
)
SELECT CAST(num AS VARCHAR(10))
+
CASE
WHEN num % 100 IN (11,12,13) THEN 'th' --first checks for exception
WHEN num % 10 = 1 THEN 'st'
WHEN num % 10 = 2 THEN 'nd'
WHEN num % 10 = 3 THEN 'rd'
ELSE 'th' --works for num % 10 IN (4,5,6,7,8,9,0)
END
FROM CTE_Numbers
OPTION (MAXRECURSION 0)

您可以像在应用层中一样轻松地执行此操作:
DECLARE @myDate DATETIME = '2015-05-21';
DECLARE @day INT;
SELECT @day = DAY(@myDate);
SELECT CASE WHEN @day IN ( 11, 12, 13 ) THEN CAST(@day AS VARCHAR(10)) + 'th'
WHEN @day % 10 = 1 THEN CAST(@day AS VARCHAR(10)) + 'st'
WHEN @day % 10 = 2 THEN CAST(@day AS VARCHAR(10)) + 'nd'
WHEN @day % 10 = 3 THEN CAST(@day AS VARCHAR(10)) + 'rd'
ELSE CAST(@day AS VARCHAR(10)) + 'th'
END
如果需要,您也可以将其置于标量函数中。

对于您的示例,它将是:
SELECT Name ,
CASE WHEN Place IN ( 11, 12, 13 )
THEN CAST(Place AS VARCHAR(10)) + 'th'
WHEN Place % 10 = 1 THEN CAST(Place AS VARCHAR(10)) + 'st'
WHEN Place % 10 = 2 THEN CAST(Place AS VARCHAR(10)) + 'nd'
WHEN Place % 10 = 3 THEN CAST(Place AS VARCHAR(10)) + 'rd'
ELSE CAST(Place AS VARCHAR(10)) + 'th'
END AS Place

我想我会添加各种选项。这是一线。大约一年前,我将此留为评论。但是有人建议我把它作为答案。所以,你去:
SELECT OrdinalRank = CONCAT(num, IIF(num % 100 IN (11,12,13),'th',COALESCE(CHOOSE(num % 10,'st','nd','rd'),'th')))
FROM (
VALUES (1),(2),(3),(4),(5),(10),(11),(20),(21),(22),(23),(24),(101),(102),(103)
) x(num)
--Result:
--1st
--2nd
--3rd
--4th
--5th
--10th
--11th
--20th
--21st
--22nd
--23rd
--24th
--101st
--102nd
--103rd
这利用了IIF
和CHOOSE
函数,它们仅在SQL 2012+中可用。
答案 9 :(得分:-1)
使用下面的SSRS表达式:
= DAY(Globals!ExecutionTime) &
SWITCH(
DAY(Globals!ExecutionTime)= 1 OR DAY(Globals!ExecutionTime) = 21 OR DAY(Globals!ExecutionTime)=31, "st",
DAY(Globals!ExecutionTime)= 2 OR DAY(Globals!ExecutionTime) = 22 , "nd",
DAY(Globals!ExecutionTime)= 3 OR DAY(Globals!ExecutionTime) = 23 , "rd",
true, "th"
)
这很容易实现并且效果很好。
