Zend db-更新不起作用

Question

I'm using Zend db to update a record in a MySQL table. I have a SELECT that gets a uuid; and then the following to update the same record:

$data = array(
    'fieldname' => 'foobar',
);

$where = array();
$where["uuid = ?"] = $uuid;

$db->update('customers', $data, $where);

Unfortunately the record does not update, and I don't get an error message. The uuid is correct.

Answer 1

I think I was missing the execute. I ended up doing something like this:

$update = $db->update('customers');
$update->where(['uuid' => $uuid]);
$update->set(['fieldname' => 'foobar']);

$statement = $db->prepareStatementForSqlObject($update);
$results = $statement->execute();

This worked fine.
