输入参数为 - 100, 'abc,def,ghi', '10,20,30'
。它们必须以
menuid(int) cid(int) code(varchar)
----------------------------------
100 10 abc
100 20 def
100 30 ghi
我已经使用该函数从此处拆分字符串 - http://www.sqlservercentral.com/blogs/querying-microsoft-sql-server/2013/09/19/how-to-split-a-string-by-delimited-char-in-sql-server/
这是我的代码
declare @menuid int = 100
declare @strcode varchar(max)='abc,def,ghi'
declare @strid varchar(max)='10,20,30'
declare @t1 table(
menuid int,
cid int,
code varchar(100)
)
;with t1 as(
select * from fnSplitString(@strid,',')
)
;with t2 as(
select * from fnSplitString(@strcode,',')
)
insert into @t1
......不知道如何从这里开始

我刚改变了用于分割和放大的功能。继续为你解决问题...
ALTER FUNCTION [dbo].[fnSplitString]
(
@string NVARCHAR(MAX),
@delimiter CHAR(1)
)
RETURNS @output TABLE(id int, splitdata NVARCHAR(MAX)
)
BEGIN
DECLARE @id INT,@start INT, @end INT
SELECT @start = 1, @end = CHARINDEX(@delimiter, @string) ,@id=1
WHILE @start < LEN(@string) + 1 BEGIN
IF @end = 0
SET @end = LEN(@string) + 1
INSERT INTO @output (id,splitdata)
VALUES(@id,SUBSTRING(@string, @start, @end - @start))
SET @start = @end + 1
SET @id = @id + 1
SET @end = CHARINDEX(@delimiter, @string, @start)
END
RETURN
END
下一步
declare @menuid int = 100
declare @strcode varchar(max)='abc,def,ghi'
declare @strid varchar(max)='10,20,30'
declare @t1 table(
menuid int,
cid int,
code varchar(100)
)
insert into @t1
select @menuid,
s1.splitdata AS cid,s2.splitdata AS code
from fnSplitString(@strid,',') s1
INNER JOIN
(
select * from fnSplitString(@strcode,',')
)s2 on s1.id=s2.id
select * from @t1

您可以更新该函数,同时为每个分割字符串返回一个数字,如下所示:
ALTER FUNCTION [dbo].[fnSplitString]
(
@string NVARCHAR(MAX),
@delimiter CHAR(1)
)
RETURNS @output TABLE(splitdata NVARCHAR(MAX), currentIndex int
)
BEGIN
DECLARE @count int = 0
DECLARE @start INT, @end INT
SELECT @start = 1, @end = CHARINDEX(@delimiter, @string)
WHILE @start < LEN(@string) + 1 BEGIN
IF @end = 0
SET @end = LEN(@string) + 1
INSERT INTO @output (splitdata, currentIndex)
VALUES(SUBSTRING(@string, @start, @end - @start), @count)
SET @start = @end + 1
SET @count += 1
SET @end = CHARINDEX(@delimiter, @string, @start)
END
RETURN
END
现在,您可以在简单查询中加入函数的结果,并将其插入到表中。
declare @menuid int = 100
declare @strcode varchar(max)='abc,def,ghi'
declare @strid varchar(max)='10,20,30'
declare @t1 table(
menuid int,
cid int,
code varchar(100)
);
INSERT INTO @t1
SELECT @menuid menuId, codes.splitdata cid, ids.splitdata code FROM fnSplitString(@strid,',') codes LEFT OUTER JOIN
fnSplitString(@strcode,',') ids ON codes.currentIndex = ids.currentIndex
