E-mail in a Query

E-mail in a Query

Question:
How do I send an e-mail to myself if a field reads “SEND_MAIL?”

For example, a user wants more info on a product, so he clicks on the Send Mail button, which in turn throws an entry into the database. This entry is SEND_MAIL. Now at the end of the day I would like the server to scan the database for the word SEND_MAIL and, when it finds one, send me an email with the name and email address of the person.

Answer:
To answer this question I took the scenario of a Web site that logs user registrations and puts a visitor’s first name, last name and e-mail address in a table. I then created a stored procedure that selects this data and e-mails it to an e-mail address provided as an input parameter. If the SendMail column in the table is Y, then the details will be e-mailed. The stored procedure is called like this:

usp_CheckForMail '[email protected]'

The script to create the table is as follows:

if exists (select * from sysobjects where id = 
object_id(N'[dbo].[TestTable]') and
OBJECTPROPERTY(id, N'IsUserTable') = 1)drop table [dbo].[TestTable]GOCREATE TABLE [dbo].[TestTable] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [Fname] [varchar] (50) NULL , [Lname] [varchar] (50) NULL , [EmailAddress] [varchar] (100) NULL , [SendMail] [char] (1) NULL ) ON [PRIMARY]GO

The script to create the stored procedure to send the e-mails is:

if exists (select * from sysobjects where id = 
object_id(N'[dbo].[usp_CheckForMail]') and
OBJECTPROPERTY(id, N'IsProcedure') = 1)drop procedure [dbo].[usp_CheckForMail]GOSET QUOTED_IDENTIFIER ON SET ANSI_NULLS ON GOCREATE PROCEDURE usp_CheckForMail @SendToEmail varchar(255)ASDECLARE @ID int, @Fname varchar(50), @Lname varchar(50),
