sql-server - SQL Server - 带长度截断的字符串分隔

所以我有一个来自搜索的字符串，它可以包含多个单词，我想将单词截断为 10 个字符，即

DECLARE @SearchString varchar(255) = 'Administration Duplication'

变成:'Administra Duplicatio'

Answer 1

来自here只需少量修改:

Create Function dbo.[getFirstTenCharacters]
(
   @String Varchar(Max) 
)
RETURNS Varchar(Max)
BEGIN
Declare @Xml Xml
Declare @firsttenletter Varchar(Max)
Declare @delimiter Varchar(5)

SET @delimiter=' '
SET @Xml = cast(('<a>'+replace(@String,@delimiter,'</a><a>')+'</a>') AS XML)

;With CTE AS (SELECT A.value('.', 'varchar(max)') as [Column]
FROM @Xml.nodes('a') AS FN(a) )
SELECT @firsttenletter =Stuff((SELECT ' ' + LEFT([Column],10)
FROM CTE
FOR XML PATH('') ),1,0,'')

RETURN (@firsttenletter)
END
GO


SELECT dbo.[getFirstTenCharacters]('Administration Duplication');
