試試看看這個代碼。
用戶自定義函數iter_charlist_to_tbl將字符串拆分爲具有已定義的分隔符的行。 （從here截取）
串的my_convert功能串連行字符串
SQL Fiddle
MS SQL Server 2008的架構設置：
create table t (str varchar(max))
go
create function my_convert(@str varchar(max))
returns varchar(max)
as
begin
declare @p_str varchar(max), @result varchar(max), @delim varchar(2)
set @delim = char(10)
set @result = ''
declare CUR cursor for
select right(str, len(str) -7) as result--, str
from dbo.iter_charlist_to_tbl(@str, @delim) t
where str like 'pseudo=%'
open CUR
fetch next from CUR into @p_str
while @@fetch_status = 0
begin
set @result = @result + @p_str + char(10)
fetch next from CUR into @p_str
end
close CUR
deallocate CUR
return @result
end
go
CREATE FUNCTION iter_charlist_to_tbl
(@list nvarchar(MAX),
@delimiter nvarchar(2) = N',')
RETURNS @tbl TABLE (listpos int IDENTITY(1, 1) NOT NULL,

SET @textpos = 1
SET @leftover = ''
WHILE @textpos <= datalength(@list)/2
BEGIN
SET @chunklen = 4000 - datalength(@leftover)/2
SET @tmpstr = @leftover + substring(@list, @textpos, @chunklen)
SET @textpos = @textpos + @chunklen
