Hi Everyone.
I am using NorthWind as an Example:
Parent Table derived from: Categories. I added a new Column E-Mail and Selecting rows where Category Id <=3. Here is my Data.
Category ID Category Name Category E-mail
1 Beverages Beverages.com
2 Condiments Condiments.com
3 Confections
Child Table derived from: Products. I am Selecting rows where Category Id <=3. Here is my Sample Data.
Category ID Product Name Quantity Per Unit
1 Chang 24 - 12 oz bottles
1 Côte de Blaye 12 - 75 cl bottles
1 Ipoh Coffee 16 - 500 g tins
1 Outback Lager 24 - 355 ml bottles
2 Aniseed Syrup 12 - 550 ml bottles
2 Chef Anton's Gumbo Mix 36 boxes
2 Louisiana Hot Spiced Okra 24 - 8 oz jars
2 Northwoods Cranberry Sauce 12 - 12 oz jars
3 Chocolade 10 pkgs.
3 Gumbär Gummibärchen 100 - 250 g bags
3 Maxilaku 24 - 50 g pkgs.
3 Scottish Longbreads 10 boxes x 8 pieces
I would like to read 1st Category Id, Category E-Mail from Categories Table (ie. Category Id = 1), find that in Products Table.
If match, extract matching records for that Category from Both Tables (Categories.CategoryID, Products.ProductName, Products.QuantityPerUnit) and e-mail them based on E-Mail Address from Parent (Categories ) Table. If no E-Mail Address is listed, do not create output file. In this instance Category Id = 3.
Basically I want to select 1st record from Parent Table (Here is Category) and search for all matching Products in Products Table. And Create an E-mail and sending just those matching records. Repeat the same process for remaining rows from Categories Table.
I am expecting my E-Mail Output like this:
For Category Id: 1
Category ID Product Name Quantity Per Unit
1 Chang 24 - 12 oz bottles
1 Côte de Blaye 12 - 75 cl bottles
1 Ipoh Coffee 16 - 500 g tins
1 Outback Lager 24 - 355 ml bottles
For Category Id: 2
Category ID Product Name Quantity Per Unit
2 Aniseed Syrup 12 - 550 ml bottles
2 Chef Anton's Gumbo Mix 36 boxes
2 Louisiana Hot Spiced Okra 24 - 8 oz jars
2 Northwoods Cranberry Sauce 12 - 12 oz jars
I am not extracting the Data for any user Interface (ie. Grid View/Form View Etc). I will just create a Command Button in an ASP.NET 2.0 form to extract Data. My Tables are in SQL 2005.
I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL?
Ideally I would like extract my records with one call to a SP. Is there any way I can run a while loop inside the SP and extract Child Data based on Parent Record?
Any Help or sample URL, Tutorial Page will be appreciated. Thanks
