In this post I have explained the way to use UDF (User Defined Functions) in constraints. For the purpose of discussion I have provided the structure of 2 (self explanatory) tables " MasterTable " and " ChildTable ". Sample data for MasterTable have also been provided below. --Table structure of MasterTable: Create Table MasterTable ( ItemID int Identity Primary Key, ItemName Varchar(50), Status bit ) --Sample data for the table MasterTable: Insert Into MasterTable (ItemName, Status) Values ('Rice',1) Insert Into MasterTable (ItemName, Status) Values ('Wheat',1) Insert Into MasterTable (ItemName, Status) Values ('Corn flakes',0) --Table structure of ChildTable: Create Table ChildTable ( ItemID int Foreign Key References MasterTable(ItemID), Quantity int ) Go /* Let us now create an user defined function to check whether the Item exist and its status is 1. According to this sample Status 1 means the record is enabled if it is 0 it is disabled....

Yesterday I created a GMail a/c (vmvadivel@gmail.com) for myself. Thought would inform you all about that. If you also have an active blogger a/c (www.blogger.com) you could see the invite for creating a Gmail account immediately after logging into the site (blogger.com). If at all you don't have an blogger account check the heading "Interested in an account" here . I guess that would help you to get a GMail id at some later date!! I was actually wondering if Google gives 1 GB of space to each user how big their servers needs to be?!??! Won't they run into storage problem within few months after they release it for public?? At that time I got to see the post from my good old friend Pandurang Nayak which had some interesting facts about GMail !!
