suppose we have three tables in the Database:
we have to fire a query of insert on the clicking of a button in asp.net with c# language.
we have to insert the company_id (from tbl_companymaster),paper_id(from tbl_papermaster),rate(sfrom tbl_papermaster) into tbl_rate Example:
tbl_companymaster:
company_id company_name
-----------------------------------
1 lalit and company
-------------------------------------
2 deepesah and co.
-----------------------------------
3 RP & Co.
-------------------------------------
tbl_papermaster:
paper_id paper_name rate
-------------------------------------------------
1 plain 400
------------------------------------------------
2 carbon 300
-------------------------------------------------
3 butter 500
tbl_rate:
rate-id company_id paper_id rate
---------------------------------------------------------------
1 1 1 400
--------------------------------------------------------------------
2 1 2 300
-----------------------------------------------------------------------
3 1 3 500
------------------------------------------------------------------------
4 2 1 400
-----------------------------------------------------------------------
5 2 2 300
---------------------------------------------------------------------
6 2 3 500
------------------------------------------------------------------------

First you should aware of Forign key and primary key relationships between the table.As well as the SQL Join. Then only u can perform this much of Insertions and DataBindings to view.

For yours Each company must have uniquidentifier.Based on the company_id (from tbl_companymaster),set Forign Key for paper_id(from tbl_papermaster),set Forign key for rate(from tbl_papermaster) into tbl_rate.Perform the coding operation based on the Key Relationships.
First clear with Relationship then do it. It will be Better.
Hope this may helpful...
