insert multiple rows from multiple tables - SQL - sql

Question

The input parameters are - 100, 'abc,def,ghi', '10,20,30'. They have to be inserted into a table as
menuid(int) cid(int) code(varchar)
----------------------------------
100 10 abc
100 20 def
100 30 ghi
I have used the function to split string from here - http://www.sqlservercentral.com/blogs/querying-microsoft-sql-server/2013/09/19/how-to-split-a-string-by-delimited-char-in-sql-server/
and here is my code
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
...do not know how to proceed from here

I just altered the function used for split & continue to get solution for you ...
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
Next Step
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

You can update the function to also return a number for each splitted string like this:
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
Now you can join the result of the function in a simple query and insert this into your table.
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
