Question

所以，如果我有这个字符串：这是为了告知我们组织的＃Department＃和＃Employees＃。我只想要这两个字#Dectate＃和#Employees＃

Answer 1

你是否愿意为此付出代价

declare @string varchar(100) ='This is to inform #Department# and #Employees# of out.............'
,@string_1st_part varchar(100)


declare @table table (col  varchar(100) )

while (CHARINDEX (' #',@string) >0)
begin
 set @string =substring (@string,CHARINDEX (' #',@string)+2,len(@string) )
 set @string_1st_part =substring (@string,1,CHARINDEX ('# ',@string))
 insert into @table
 select  '#'+@string_1st_part
end

select *from  @table

首先在数据库中创建拆分功能

CREATE FUNCTION [dbo].[Split]
(
    @String NVARCHAR(4000),
    @Delimiter NCHAR(1)
)
RETURNS TABLE
AS
RETURN
(
    WITH Split(stpos,endpos)
    AS(
        SELECT 0 AS stpos, CHARINDEX(@Delimiter,@String) AS endpos
        UNION ALL
        SELECT endpos+1, CHARINDEX(@Delimiter,@String,endpos+1)
            FROM Split
            WHERE endpos > 0
    )
    SELECT 'Id' = ROW_NUMBER() OVER (ORDER BY (SELECT 1)),
        'Data' = SUBSTRING(@String,stpos,COALESCE(NULLIF(endpos,0),LEN(@String)+1)-stpos)
    FROM Split
)
GO

然后使用以下代码行获得适当的输出

declare @str varchar(100) ='This is to inform #Department# and #Employees# of out.............'


SELECT data from  [dbo].[Split]  (@str,'#')
WHERE ID%2=0

如何根据起始＆＃39;＃＆＃39;分割以下字符串？性格和结尾的角色＆＃39;＃＆＃39;在TSql？
