SQL后逗号分隔值后的第三位

Question

我有一个字符串，我想逗号后的第三个地方的单词。

id String 
1  India,Pakistan,China,Turkey,England 
2  USA,UK,Pakistan,India 
3  China,North Korea,Turkey,Iran 

所需的结果将是

id String 
1  China 
2  Pakistan 
3  Turkey 

Answer 1

需要的输出可以使用来实现，

语法：

SELECT COALESCE(LTRIM(CAST(('<X>'+REPLACE(<column_name>,',' ,'</X><X>')+'</X>') AS XML).value('(/X)[3]', 'varchar(100)')), '') AS String 
FROM <table_name> 

有问题的表格中自定义查询：

SELECT id, 
    COALESCE(LTRIM(CAST(('<X>'+REPLACE(String,',' ,'</X><X>')+'</X>') AS XML).value('(/X)[3]', 'varchar(100)')), '') AS String 
FROM table_1 

Answer 2

您可以使用xml value这样

DECLARE @SampleData AS TABLE 
(
    Id int IDENTITY (1,1), 
    String varchar(200) 
) 

INSERT INTO @SampleData 
VALUES (' India,Pakistan,China,Turkey,England'), ('USA,UK,Pakistan,India'),('China,North Korea,Turkey,Iran') 


;WITH temps AS 
(
    SELECT sd.Id ,CAST('<x>' + replace(sd.String, ',', '</x><x>') + '</x>' as xml) AS String 
    FROM @SampleData sd 
) 
SELECT t.Id, t.String.value('(/x)[3]','varchar(50)') 
FROM temps t
