Where mail sql
You're looking for a way to send an email using SQL!
There are a few ways to send an email using SQL, depending on the database management system (DBMS) you're using. Here are a few examples:
MySQL
In MySQL, you can use the mysql
command-line tool to send an email using the SELECT
statement. Here's an example:
SELECT SLEEP(10);
SELECT @body := 'Hello, world!';
SELECT @subject := 'Test email';
SELECT @from := '[email protected]';
SELECT @to := '[email protected]';
SELECT @server := 'smtp.example.com';
SELECT @port := 587;
SELECT @username := '[email protected]';
SELECT @password := 'your_password';
PREPARE stmt FROM 'SET @body =?';
EXECUTE stmt USING @body;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @subject =?';
EXECUTE stmt USING @subject;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @from =?';
EXECUTE stmt USING @from;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @to =?';
EXECUTE stmt USING @to;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @server =?';
EXECUTE stmt USING @server;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @port =?';
EXECUTE stmt USING @port;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @username =?';
EXECUTE stmt USING @username;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SET @password =?';
EXECUTE stmt USING @password;
DEALLOCATE PREPARE stmt;
PREPARE stmt FROM 'SELECT @body, @subject, @from, @to, @server, @port, @username, @password';
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
This will send an email using the mysql
command-line tool. You'll need to replace the placeholders with your actual email credentials and settings.
PostgreSQL
In PostgreSQL, you can use the pg_send_query
function to send an email using the plpgsql
language. Here's an example:
CREATE OR REPLACE FUNCTION send_email()
RETURNS void AS $$
DECLARE
body text;
subject text;
from_email text;
to_email text;
server text;
port integer;
username text;
password text;
BEGIN
body := 'Hello, world!';
subject := 'Test email';
from_email := '[email protected]';
to_email := '[email protected]';
server := 'smtp.example.com';
port := 587;
username := '[email protected]';
password := 'your_password';
PERFORM pg_send_query('SET @body = ''' || body || ''''');
PERFORM pg_send_query('SET @subject = ''' || subject || ''''');
PERFORM pg_send_query('SET @from = ''' || from_email || ''''');
PERFORM pg_send_query('SET @to = ''' || to_email || ''''');
PERFORM pg_send_query('SET @server = ''' || server || ''''');
PERFORM pg_send_query('SET @port = ' || port::text);
PERFORM pg_send_query('SET @username = ''' || username || ''''');
PERFORM pg_send_query('SET @password = ''' || password || ''''');
PERFORM pg_send_query('SELECT @body, @subject, @from, @to, @server, @port, @username, @password');
END;
$$ LANGUAGE plpgsql;
This will send an email using the pg_send_query
function. You'll need to replace the placeholders with your actual email credentials and settings.
SQL Server
In SQL Server, you can use the xp_sendmail
extended stored procedure to send an email. Here's an example:
CREATE PROCEDURE send_email
AS
BEGIN
DECLARE @body nvarchar(4000);
DECLARE @subject nvarchar(255);
DECLARE @from nvarchar(255);
DECLARE @to nvarchar(255);
DECLARE @server nvarchar(255);
DECLARE @port int;
DECLARE @username nvarchar(255);
DECLARE @password nvarchar(255);
SET @body = 'Hello, world!';
SET @subject = 'Test email';
SET @from = '[email protected]';
SET @to = '[email protected]';
SET @server = 'smtp.example.com';
SET @port = 587;
SET @username = '[email protected]';
SET @password = 'your_password';
EXEC xp_sendmail @body, @subject, @from, @to, @server, @port, @username, @password;
END;
This will send an email using the xp_sendmail
extended stored procedure. You'll need to replace the placeholders with your actual email credentials and settings.
Note that these examples are just a starting point, and you'll likely need to modify them to fit your specific use case. Additionally, be aware of any security concerns when sending emails from your database.
