我有这个参数
@ID varchar = '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20'
我想做一些事情来拆分逗号分隔的值。
string_split 函数不起作用，我收到此错误：
STRING_SPLIT 函数仅在兼容级别 130 下可用
我尝试更改我的数据库并将兼容性设置为 130，但我没有此更改的权限。

谢谢al3x-m。 我创建了这个函数以便在很多时候重复使用。
CREATE FUNCTION STRING_SPLIT_POLYFILL2016 (
@string NVARCHAR(4000)
,@separator NVARCHAR(4000)
)
RETURNS @T TABLE (ColName VARCHAR(4000))
AS
BEGIN

DECLARE @Number VARCHAR(4000);
SET @string = @string + @separator;
WHILE CHARINDEX(@separator, @string) > 0
BEGIN
SET @Number = SUBSTRING(@string, 0, CHARINDEX(@separator, @string));
SET @string = SUBSTRING(@string, CHARINDEX(@separator, @string) + 1, LEN(@string));
INSERT INTO @T (ColName)
VALUES (@Number)
END
RETURN
END
-- 演示
DECLARE @IDS NVARCHAR(4000)
SET @IDS = "pitt,phunsanit,01,02,03,4,5,6,7,8,9,10,พิชญ์,พันธุ์สนิท"
SELECT *
FROM STRING_SPLIT_POLYFILL2016(@IDS, ",")
【讨论】：
旧版本 SQL Server 的 String_Split 的替代函数
在你的数据库中创建这个函数
Create Function dbo.Test_Split( @string varchar(4000))
Returns
@Result Table (value varchar(100))
As
Begin
declare @len int, @loc int = 1
While @loc <= len(@string)
Begin
Set @len = CHARINDEX(',', @string, @loc) - @loc
If @Len < 0 Set @Len = len(@string)
Insert Into @Result Values (SUBSTRING(@string,@loc,@len))
Set @loc = @loc + @len + 1
End
Return
End
如何使用
Select
*
From
dbo.Test_Split('First,Second,Third,Fourth')
【讨论】：
添加另一种拆分字符串的方法。我用的更快。特别是拆分日志字符串。更多信息请参考：https://sqlperformance.com/2012/07/t-sql-queries/split-strings
create FUNCTION [dbo].[UFN_STRING_SPLIT]
(
@List NVARCHAR(MAX),
@Delimiter NVARCHAR(255)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
RETURN
(
SELECT Item = y.i.value('(./text())[1]', 'nvarchar(max)')
FROM
(
SELECT x = CONVERT(XML, '<i>'
+ REPLACE(@List, @Delimiter, '</i><i>')
+ '</i>').query('.')
) AS a
CROSS APPLY x.nodes('i') AS y(i)
);

【讨论】：
string_split 功能，您必须评论 id 行。 id 在您必须从两个字符串中插入两列（'a1,b1,c1' 到 Column1 和 'a2,b2,c2' 到 Column2 例如）到一个表中时非常有用/舒适。
对于那些寻找如何将多行文本转换为行的人，这里是基于the answer 的代码：
declare @text varchar(max) = 'line0
line1
line2'
select split.a.value('.', 'nvarchar(max)') data
from
(
select cast('<x>' + replace(@text, char(13) + char(10), '</x><x>') + '</x>' as xml) as string
) as a
cross apply string.nodes('/x') as split(a)

@Al3x_M 的 polyfill 的一些变化，当无法更改数据库兼容级别时：我使用 TABLE 变量来存储值列表，以便稍后在另一个查询中使用它们：
DECLARE @IDs VARCHAR(500);
SET @IDs = '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,2a0' ;
declare @list TABLE (id int);
DECLARE @Number int, @idx int
DECLARE @charSpliter CHAR;
SET @charSpliter = ','
SET @IDs = @IDs + @charSpliter;
set @idx = 0
WHILE (1 = 1)
BEGIN
set @idx = CHARINDEX(@charSpliter, @IDs)
if (@idx is NULL or @idx <= 0) break;
BEGIN TRY
SET @Number = SUBSTRING(@IDs, 0, @idx)
SET @IDs = SUBSTRING(@IDs, @idx + 1, LEN(@IDs))
insert @list select convert(int, @Number)
END TRY
BEGIN CATCH
break
END CATCH
END
-- @list available for the next query...
select * from @list

另一种方法是在 WHILE 中使用 CHARINDEX 和 SUBSTRING：
DECLARE @IDs VARCHAR(500);
DECLARE @Number VARCHAR(500);
DECLARE @charSpliter CHAR;
SET @charSpliter = ',';
SET @IDs = '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20' + @charSpliter;
WHILE CHARINDEX(@charSpliter, @IDs) > 0
BEGIN
SET @Number = SUBSTRING(@IDs, 0, CHARINDEX(@charSpliter, @IDs));
SET @IDs = SUBSTRING(@IDs, CHARINDEX(@charSpliter, @IDs) + 1, LEN(@IDs));
PRINT @Number;
END;

其他方法也可以使用XML 方法和CROSS APPLY 来拆分您的逗号分隔数据：
SELECT Split.a.value('.', 'NVARCHAR(MAX)') DATA
FROM
(
SELECT CAST('<X>'+REPLACE(@ID, ',', '</X><X>')+'</X>' AS XML) AS String
) AS A
CROSS APPLY String.nodes('/X') AS Split(a);
结果：
DATA
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
例子：
DECLARE @ID NVARCHAR(300)= '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20';
DECLARE @Marks NVARCHAR(300)= '0,1,2,5,8,9,4,6,7,3,5,2,7,1,9,4,0,2,5,0';
DECLARE @StudentsMark TABLE
(id NVARCHAR(300),
marks NVARCHAR(300)
);
--insert into @StudentsMark
;WITH CTE
AS (
SELECT Split.a.value('.', 'NVARCHAR(MAX)') id,
ROW_NUMBER() OVER(ORDER BY
(
SELECT NULL
)) RN
FROM
(
SELECT CAST('<X>'+REPLACE(@ID, ',', '</X><X>')+'</X>' AS XML) AS String
) AS A
CROSS APPLY String.nodes('/X') AS Split(a)),
CTE1
AS (
SELECT Split.a.value('.', 'NVARCHAR(MAX)') marks,
ROW_NUMBER() OVER(ORDER BY
(
SELECT NULL
)) RN
FROM
(
SELECT CAST('<X>'+REPLACE(@Marks, ',', '</X><X>')+'</X>' AS XML) AS String
) AS A
CROSS APPLY String.nodes('/X') AS Split(a))
INSERT INTO @StudentsMark
SELECT C.id,
C1.marks
FROM CTE C
LEFT JOIN CTE1 C1 ON C1.RN = C.RN;
SELECT *
FROM @StudentsMark;

如果您的数据库兼容级别低于130，SQL Server 将无法找到并执行STRING_SPLIT 函数。您可以使用以下命令更改数据库的兼容性级别：
ALTER DATABASE DatabaseName SET COMPATIBILITY_LEVEL = 130
请注意，即使在新的 Azure SQL 数据库中，兼容性级别 120 也可能是默认值。
供参考：
版本 - 最高兼容级别 - 最低可用级别
SQL 2017 - 140 - 100
SQL 2016 - 130 - 100
SQL 2014 - 120 - 100
SQL 2012 - 110 - 90
SQL 2008 - 100 - 80
SQL 2005 - 90 - 80
SQL 2000 - 80 - 80
另外，请检查您的语法，例如：
SELECT Value FROM STRING_SPLIT('Lorem ipsum dolor sit amet.', ' ');
