How Can I Verify Successful MySQL Insertion Using PDO?

PDO MySQL: Determining Insertion Success

When performing an insertion operation using PDO with MySQL, you may encounter the need to verify its success. This is especially relevant when you want programmatic feedback rather than manually inspecting the database.

To determine if an insertion was successful, you can utilize the following approaches:

PDOStatement->execute() Method:

The PDOStatement->execute() method returns a boolean value, indicating the success or failure of the query execution. If the insertion is successful, it will return true. Otherwise, it will return false.

PDOStatement->errorCode() Method:

In addition to PDOStatement->execute(), you can also use the PDOStatement->errorCode() method. This method returns the error code associated with any execution errors. If the insertion is successful, the returned error code will be null or 0. On the other hand, if an error occurs, this method will return a non-zero error code.

Example:

$stmt = $pdo->prepare("INSERT INTO table (field1, field2) VALUES (:field1, :field2)");
$stmt->bindParam(':field1', $field1, PDO::PARAM_STR);
$stmt->bindParam(':field2', $field2, PDO::PARAM_STR);

if ($stmt->execute()) {
    // Insertion successful
} else {
    // Insertion failed
    $errorCode = $stmt->errorCode();
}

By leveraging these methods, you can programmatically ascertain the success or failure of an insertion when using PDO with MySQL, providing valuable information for error handling and feedback purposes.
