How Can I Verify a Successful PDO MySQL INSERT Operation?

How to Determine the Success of a PDO MySQL Insert Operation

Performing data manipulation operations with PDO can provide a convenient and secure way to interact with a database. However, it's crucial to ensure the successful execution of these operations, especially when inserting data.

The PDO MySQL module offers several ways to check if an insert operation has been executed successfully:

PDOStatement::execute() Return Value:

The PDOStatement::execute() method returns a boolean value indicating the success or failure of the operation. True is returned if the insert was successful, and false otherwise.

PDOStatement::errorCode() Method:

If the insert operation fails, the PDOStatement::errorCode() method can be used to retrieve the error code associated with the failure. This error code can be useful for debugging and understanding the cause of the failure.

Example:

The following code demonstrates how to use these techniques to check the success of an insert operation:

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

if ($stmt->execute()) {
    echo "Insert successful";
} else {
    $error_code = $stmt->errorCode();
    echo "Insert failed with error code $error_code";
}

By leveraging the provided methods, you can handle the outcome of insert operations programmatically, ensuring that your data integrity and application flow are maintained as expected.
