how to get last inserted Id of a Sqlite database using Zend_Db

Question

I\'m trying to fetch the last inserted row Id of a Sqlite DB in my PHP application. I\'m using Zend Framework\'s PDO Sqlite adapter for database handling. the lastInsertId()

Answer 1

Do not use

SELECT * FROM tablename WHERE id = (SELECT COUNT(*) FROM tablename);

instead use

SELECT MAX(id) as id FROM tablename LIMIT 1;

or

SELECT id FROM tablename ORDER DESC LIMIT 1;

Answer 2

PDO::lastInserId()

see: http://us2.php.net/manual/en/pdo.lastinsertid.php

Answer 3

SELECT * FROM [tablename] ORDER BY id DESC LIMIT 1

Answer 4

Hey, try this query. But I don't know about PHP.

SELECT *
FROM tablename
WHERE id = (SELECT COUNT(*) FROM tablename);

Answer 5

Given an SQLite3 Database with a table b, as follows:

BEGIN TRANSACTION;
CREATE TABLE b(a integer primary key autoincrement, b varchar(1));
COMMIT;

This code gives me a lastInsertId:

public function lastInsertId() {
    $result = $this->_connection->query('SELECT last_insert_rowid() as last_insert_rowid')->fetch();
    return $result['last_insert_rowid'];
}

That is - if your table is defined correctly, your only problem is likely to be that you tried to fetch key $result[0] - also, whenever you're using a computed column, I recommend aliasing the column using the "AS" keyword as I've demonstrated above. If you don't want to alias the column, in SQLite3 the column should be named "last_insert_rowid()".
