Inserting data in 2 table on the same form [duplicate] - php

Question

Assuming that I have two tables, names and phones,
and I want to insert data from some input to the tables, in one query. How can it be done?

Answer 1

You can't. However, you CAN use a transaction and have both of them be contained within one transaction.
START TRANSACTION;
INSERT INTO table1 VALUES ('1','2','3');
INSERT INTO table2 VALUES ('bob','smith');
COMMIT;

Answer 2

MySQL doesn't support multi-table insertion in a single INSERT statement. Oracle is the only one I'm aware of that does, oddly...
INSERT INTO NAMES VALUES(...)
INSERT INTO PHONES VALUES(...)

Answer 3

Old question, but in case someone finds it useful... In Posgresql, MariaDB and probably MySQL 8+ you might achieve the same thing without transactions using WITH statement.
WITH names_inserted AS (
INSERT INTO names ('John Doe') RETURNING *
), phones_inserted AS (
INSERT INTO phones (id_name, phone) (
SELECT names_inserted.id, '123-123-123' as phone
) RETURNING *
) SELECT * FROM names_inserted
LEFT JOIN phones_inserted
ON
phones_inserted.id_name=names_inserted.id
This technique doesn't have much advantages in comparison with transactions in this case, but as an option... or if your system doesn't support transactions for some reason...
P.S. I know this is a Postgresql example, but it looks like MariaDB have complete support of this kind of queries. And in MySQL I suppose you may just use LAST_INSERT_ID() instead of RETURNING * and some minor adjustments.

Answer 4

I had the same problem. I solve it with a for loop.
Example:
If I want to write in 2 identical tables, using a loop
for x = 0 to 1
if x = 0 then TableToWrite = "Table1"
if x = 1 then TableToWrite = "Table2"
Sql = "INSERT INTO " & TableToWrite & " VALUES ('1','2','3')"
NEXT
either
ArrTable = ("Table1", "Table2")
for xArrTable = 0 to Ubound(ArrTable)
Sql = "INSERT INTO " & ArrTable(xArrTable) & " VALUES ('1','2','3')"
NEXT
If you have a small query I don't know if this is the best solution, but if you your query is very big and it is inside a dynamical script with if/else/case conditions this is a good solution.

Answer 5

my way is simple...handle one query at time,
procedural programming
works just perfect
//insert data
$insertQuery = "INSERT INTO drivers (fname, sname) VALUES ('$fname','$sname')";
//save using msqli_query
$save = mysqli_query($conn, $insertQuery);
//check if saved successfully
if (isset($save)){
//save second mysqli_query
$insertQuery2 = "INSERT INTO users (username, email, password) VALUES ('$username', '$email','$password')";
$save2 = mysqli_query($conn, $insertQuery2);
//check if second save is successfully
if (isset($save2)){
//save third mysqli_query
$insertQuery3 = "INSERT INTO vehicles (v_reg, v_make, v_capacity) VALUES('$v_reg','$v_make','$v_capacity')";
$save3 = mysqli_query($conn, $insertQuery3);
//redirect if all insert queries are successful.
header("location:login.php");
}
}else{
echo "Oopsy! An Error Occured.";
}

Answer 6

Multiple SQL statements must be executed with the mysqli_multi_query() function.
Example (MySQLi Object-oriented):
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";
if ($conn->multi_query($sql) === TRUE) {
echo "New records created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
