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.
