I have something like this:
$stmt = $this->getDoctrine()->getConnection()->prepare(
'insert into someTable (columnList) values (parameters);');
/*
bind parameters
*/
$stmt->execute();
How do I get the last inserted ID?
Thanks,
Scott
You'll want to use lastInsertId().
Example:
$dbh = Doctrine_Manager::getInstance()->getCurrentConnection();
$sth = $dbh->prepare("INSERT INTO continent (created_at, updated_at) VALUES ( NOW(), NOW() )");
$sth->execute();
$conn = Doctrine_Manager::getInstance()->getCurrentConnection();
$conn->lastInsertId('continent_id');
The code below answers the question correctly:
//This call will get the doctrine connection from inside a symfony2 controller
$conn = $this->getDoctrine()->getConnection();
$stmt = $conn->prepare(
'insert into someTable (columnList) values (parameters);');
/*
bind parameters
*/
$stmt->execute();
$id = $conn->lastInsertId();
To get the connection from inside a doctrine repository class that you have created:
$conn = $this->getEntityManager()->getConnection();

I have a query, and I want to get the last ID inserted. The field ID is the primary key and auto incrementing.
I know that I have to use this statement:
LAST_INSERT_ID()
That statement works with a query like this:
$query = "INSERT INTO `cell-place` (ID) VALUES (LAST_INSERT_ID())";
But if I want to get the ID using this statement:
$ID = LAST_INSERT_ID();
I get this error:
Fatal error: Call to undefined function LAST_INSERT_ID()
What am I doing wrong?
That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().
Like:
$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();
If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:
$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();
lastInsertId() only work after the INSERT query.
Correct:
$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass)
VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();
Incorrect:
$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0
You can get the id of the last transaction by running lastInsertId() method on the connection object($conn).
Like this $lid = $conn->lastInsertId();

Below is my code.I want to access the last inserted id. Since I use static connection variable , it gives me error accesssing it in this way:
$insertedId = $stmt->connection::$pdo->lastInsertId() ;
public function addCar()
{
$this->rate=$param6;
if(!empty($this->name))
{
$sql="INSERT INTO car(car_name,car_maker,car_type,car_colour,num_passanger)VALUES('{$this->name}','{$this->maker}', '{$this->type}','{$this->colour}','{$this->passanger}')";
$stmt =connection::$pdo->prepare($sql);
$stmt->execute();
echo "inserted id ".$insertedId = $stmt->lastInsertId() ;
}
//$this->rentalRate();
}
UPDATE:
Simple way to use the lastInsertId() is:
// your connection with database
$con = new PDO("mysql:host=$hostname;dbname=$dbname",$dbuser,$dbpass);
// insert query
$query = "INSERT INTO tbl_name SET col_name1 = ?, col_name2 = ?";
// '$con' is your PDO connection variable
$stmt = $con->prepare($query);
$stmt->bindParam(1, $variable1); // value for col_name1 to be stored
$stmt->bindParam(2, $variable2); // value for col_name2 to be stored
$stmt->execute();
....
// gives current inserted id
$lastId = $con->lastInsertId();
In your case try: $lastId = connection::$pdo->lastInsertId();
This is the code that makes the error:
$sql = 'INSERT INTO pedidos (pagado, instalado) VALUES ("'.$_POST['email'].'", "'.$_POST['b'].'") WHERE email="'.$_POST['2'].'"';
$stm = $conn->prepare($sql);
$conn->exec($stm);
That's not the proper way to use prepare and execute. The reason this was created was so that you wouldn't need to put logic and data together and put yourself at risk of an SQL injection attack.
$sql = 'INSERT INTO pedidos (pagado, instalado) VALUES (:pagado, :instalado)';
$stm = $conn->prepare($sql);
$stm->bindParam(':pagado', $_POST['email']);
$stm->bindParam(':instalado', $_POST['b']);
$stm->execute();
It also doesn't make sense to put a WHERE in an INSERT query. You're inserting into your table, you're not getting data.
However, if you're updating data based on other data, then you should use an UPDATE query.
UPDATE pedidos SET pagado=?, instalado=? WHERE email=?
An example of this would be:
$sql = 'UPDATE pedidos SET pagado=:padago, instalado=:instalado WHERE email=:email';
$stm = $conn->prepare($sql);
$stm->bindParam(':pagado', $_POST['email']);
$stm->bindParam(':instalado', $_POST['b']);
$stm->bindParam(':email', $_POST['2']);
$stm->execute();
UPDATE - 2:
$sql = 'INSERT INTO pedidos SET pagado = ?, instalado = ? WHERE email = ?';
$stm = $conn->prepare($sql);
$stm->bindParam(1,$_POST['email']);
$stm->bindParam(2,$_POST['b'] );
$stm->bindParam(3,$_POST['2'] );
$stm->execute(); // here your code generate error
Reason: You put $stm in execute() , which makes an error.

I've tried following the PHP.net instructions for doing SELECT queries but I am not sure the best way to go about doing this.
I would like to use a parameterized SELECT query, if possible, to return the ID in a table where the name field matches the parameter. This should return one ID because it will be unique.
I would then like to use that ID for an INSERT into another table, so I will need to determine if it was successful or not.
I also read that you can prepare the queries for reuse but I wasn't sure how this helps.
You select data like this:
$db = new PDO("...");
$statement = $db->prepare("select id from some_table where name = :name");
$statement->execute(array(':name' => "Jimbo"));
$row = $statement->fetch(); // Use fetchAll() if you want all results, or just iterate over the statement, since it implements Iterator
You insert in the same way:
$statement = $db->prepare("insert into some_other_table (some_id) values (:some_id)");
$statement->execute(array(':some_id' => $row['id']));
I recommend that you configure PDO to throw exceptions upon error. You would then get a PDOException if any of the queries fail - No need to check explicitly. To turn on exceptions, call this just after you've created the $db object:
$db = new PDO("...");
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
I've been working with PDO lately and the answer above is completely right, but I just wanted to document that the following works as well.
$nametosearch = "Tobias";
$conn = new PDO("server", "username", "password");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sth = $conn->prepare("SELECT `id` from `tablename` WHERE `name` = :name");
$sth->bindParam(':name', $nametosearch);
// Or sth->bindParam(':name', $_POST['namefromform']); depending on application
$sth->execute();
You can use the bindParam or bindValue methods to help prepare your statement.
It makes things more clear on first sight instead of doing $check->execute(array(':name' => $name)); Especially if you are binding multiple values/variables.
Check the clear, easy to read example below:
$q = $db->prepare("SELECT id FROM table WHERE forename = :forename and surname = :surname LIMIT 1");
$q->bindValue(':forename', 'Joe');
$q->bindValue(':surname', 'Bloggs');
$q->execute();
if ($q->rowCount() > 0){
$check = $q->fetch(PDO::FETCH_ASSOC);
$row_id = $check['id'];
// do something
}
If you are expecting multiple rows remove the LIMIT 1 and change the fetch method into fetchAll:
$q = $db->prepare("SELECT id FROM table WHERE forename = :forename and surname = :surname");// removed limit 1
$q->bindValue(':forename', 'Joe');
$q->bindValue(':surname', 'Bloggs');
$q->execute();
if ($q->rowCount() > 0){
$check = $q->fetchAll(PDO::FETCH_ASSOC);
//$check will now hold an array of returned rows.
//let's say we need the second result, i.e. index of 1
$row_id = $check[1]['id'];
// do something
}
A litle bit complete answer is here with all ready for use:
$sql = "SELECT `username` FROM `users` WHERE `id` = :id";
$q = $dbh->prepare($sql);
$q->execute(array(':id' => "4"));
$done= $q->fetch();
echo $done[0];
Here $dbh is PDO db connecter, and based on id from table users we've get the username using fetch();
I hope this help someone, Enjoy!
Method 1:USE PDO query method
$stmt = $db->query('SELECT id FROM Employee where name ="'.$name.'"');
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
Getting Row Count
$stmt = $db->query('SELECT id FROM Employee where name ="'.$name.'"');
$row_count = $stmt->rowCount();
echo $row_count.' rows selected';
Method 2: Statements With Parameters
$stmt = $db->prepare("SELECT id FROM Employee WHERE name=?");
$stmt->execute(array($name));
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
Method 3:Bind parameters
$stmt = $db->prepare("SELECT id FROM Employee WHERE name=?");
$stmt->bindValue(1, $name, PDO::PARAM_STR);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
**bind with named parameters**
$stmt = $db->prepare("SELECT id FROM Employee WHERE name=:name");
$stmt->bindValue(':name', $name, PDO::PARAM_STR);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
or
$stmt = $db->prepare("SELECT id FROM Employee WHERE name=:name");
$stmt->execute(array(':name' => $name));
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
Want to know more look at this link
if you are using inline coding in single page and not using oops than go with this full example, it will sure help
//connect to the db
$dbh = new PDO('mysql:host=localhost;dbname=mydb', dbuser, dbpw);
//build the query
$query="SELECT field1, field2
FROM ubertable
WHERE field1 > 6969";
//execute the query
$data = $dbh->query($query);
//convert result resource to array
$result = $data->fetchAll(PDO::FETCH_ASSOC);
//view the entire array (for testing)
print_r($result);
//display array elements
foreach($result as $output) {
echo output[field1] . " " . output[field1] . "<br />";
}
