SQL INSERT INTO multiple tables

Question

How can you make one query of this two?? I will insert data into two tables.

 $query = "
              INSERT INTO dc_mail_users (
                  i_id_pk, c_user, c_passwd_md5, i_user_active_id_fk, i_user_type_id_fk
              ) VALUES (
                  %1%, %2%, %3%, %4%, %5%
              )";

 $query2 = "
              INSERT INTO dc_mail_user_data (
                   i_id_ut, c_user_sex, c_user_name, c_user_surname, c_user_url
              ) VALUES (
                  %1%, %2%, %3%, %4%, %5%
              )";

You cannot insert into 2 tables with one query.

You would need to use a stored procedure where you can put that inserts.

What's the purpose of this? Are you trying to insert data into two different tables from one HTML form? I don't know about stored procedures but I use a transaction in similar case like this:

$d = dbSingle::dbLink();
//set autocommit to false
mysqli_autocommit($d->getDbc(), FALSE);

$query = " INSERT INTO dc_mail_users (
              i_id_pk, c_user, c_passwd_md5, i_user_active_id_fk, i_user_type_id_fk
          ) VALUES (
              %1%, %2%, %3%, %4%, %5%
          )";

$r = $d->sqlQ($query);

//get the last inserted id for the second query
$last_insert_id = $d->getInsertId();                    

$query2 = "
          INSERT INTO dc_mail_user_data (
               i_id_ut, c_user_sex, c_user_name, c_user_surname, c_user_url
          ) VALUES (
              %{$last_insert_id}%, %2%, %3%, %4%, %5% //not sure about the syntax, sorry
          )";


$r2 = $d->sqlQ($query2);

//rollback if either one of the queries failed
if (!$r || (isset($r2) && !$r2)) {
  mysqli_rollback($d->getDbc());
}
  else  {
    //commit if everything worked
    mysqli_commit($d->getDbc());

  //autocommit on
  mysqli_autocommit($d->getDbc(), TRUE);
  }

This assumes i_id_ut in the table dc_mail_user_data is the FK and the i_id_pk is an auto increment field. I have a class called dbSingle that contains the query functions and database connection. Hope it's clear enough to be used with regular mysqli functions.

You can do with trigger or stored procedures but not with simple insert query.

$query  = "
              INSERT INTO dc_mail_users 
                  (i_id_pk, c_user, c_passwd_md5, i_user_active_id_fk, i_user_type_id_fk) 
              VALUES (%1%, %2%, %3%, %4%, %5%)
          ";  

$query2 = "
             INSERT INTO dc_mail_user_data 
                  (c_user_sex, c_user_name, c_user_surname, c_user_url) 
             VALUES (%1%, %2%, %3%, %4%)";

// start query 1           
$dbh = new DB_Mysql_Extended;
$dbh->prepare($query)->execute($this->i_id_pk, $this->c_user, $this->c_passwd_md5, $this->i_user_active_id_fk, $this->i_user_type_id_fk);

// start query 2
$dbh2 = new DB_Mysql_Extended;
$dbh2->prepare($query2)->execute($this->c_user_sex, $this->c_user_name, $this->c_user_surname, $this->c_user_url);
