问题
I have a procedure for insert in multiple dependent tables (update in case record exist). I have input parameters as comma separated string which I am reading in table.
After 1st insertion I am getting InsertedIds in another table variable. I am struggling over how to do insert in 2nd table. I have following input parameters for 2nd table:
Declare @IdsToBeUpdated table (primary key identity pkey, id int) -- values are 1,-1,3,-1
Declare @CommentsTobeInserted table( primary key identity pkey, comment varchar (max)) -- values are 'com1', 'com2', 'com3'
-1 input in table @IdsToBeUpdated depicts insertion for the corresponding rows in all input tables and value other than -1 depicts that records at that pkey value in all other tables (@CommentsTobeInserted table as in example) have to be updated.
So after first insertion I am getting the inserted ids for rows with -1 value. @InsertedIds = 4,5
So my Ids list logically would become.. 1,4,3,5.
But I am stuck now how to insert/update records in second table respectively. 2nd table would be like follows:
Pkey Primary key identity, commentIds(coming from inserted ids and @IdsToBeUpdated), comments.
I have added one more InsertedIds column in @CommentsTobeInserted. If I could fill it with right InsertedId against correct row, I guess I would be able to do insert/update in 2nd table. And where the value is Id in new column I would do insert, where it's null, I would perform update using @IdsToBeUpdated table. But currently none of my approach is working. I am new to SQL. Any help would be highly appreciated.
Following is some portion of script for better understanding. I have added first insertion script as well.

----------------------------Now similarly I have to do insert/update in Comments Table. But
----------------------------Comments table has RequestDetails Id column as foreign key. So
----------------------------now the challange is to add the rows with Inserted ID where value was = -1
----------------------------in input. We have got the IDs corresponding to -1 values from above insertion
----------------------------in the @InsertedIDList Table variable
-----------------------------------------------------------------------------------------
----------------------------Following is what I have tried so far. But I am not able to insert
----------------------------correct InsertedId against correct record.
----------------------------------------------------------------------------------------
-----------------------Here I tried to insert the new generated ids against corresponding comments in table variable.
-----------------------So that I can perform insert where value is not null. As NULL would be inserted where new ID has not been created
-----------------------and corresponding updated ID exists in input (Values not equal to -1)
-------------------------------------------------------------------------------------------------
Update @ProductComments set insertedId = i.ID from ---------This query is not working
(select A.pkey, B.id as detailId, row_number() over (order by (select 0)) as row_num from
@ProductComments A
JOIN @ReqDetailsIds B ON B.pkey = A.pkey) as mappedNewIds right join
@InsertedIDList i on i.pkey = mappedNewIds.row_num
where mappedNewIds.pkey = [@ProductComments].pkey
----Insert in CommentsTable for New Comments against request
---------------------------------
INSERT INTO [dbo].CommentsTable

SELECT A.insertedId, A.Comment, GETDATE()
