Question

How can I test to see if the following query executed successfully?

$STH = $this->_db->prepare("UPDATE UserCreds SET
    VerificationString=:newVerificationString, ExpiryDate=:expiryDate 
    WHERE UserID = :userID;");
$STH->execute($params);

I know I can use lastInsertId() when I’m adding new rows, but what about UPDATEs and SELECTs?

Answer 1

The execute returns true on success and false on failure.

From Docs:

Returns TRUE on success or FALSE on failure.

So you can make sure query ran successfully like:

if ($STH->execute($params))
{
  // success
}
else
{
  // failure
}
