Executes the insert query.

Return value

The last insert ID of the query, if one exists. If the query was given multiple sets of values to insert, the return value is undefined. If no fields are specified, this method will do nothing and return NULL. That That makes it safe to use in multi-insert loops.

Code

public function execute() {

  // If validation fails, simply return NULL. Note that validation routines
  // in preExecute() may throw exceptions instead.
  if (!$this
    ->preExecute()) {
    return NULL;
  }

  // If we're selecting from a SelectQuery, finish building the query and
  // pass it back, as any remaining options are irrelevant.
  if (!empty($this->fromQuery)) {
    $sql = (string) $this;

    // The SelectQuery may contain arguments, load and pass them through.
    return $this->connection
      ->query($sql, $this->fromQuery
      ->getArguments(), $this->queryOptions);
  }
  $last_insert_id = 0;

  // Each insert happens in its own query in the degenerate case. However,
  // we wrap it in a transaction so that it is atomic where possible. On many
  // databases, such as SQLite, this is also a notable performance boost.
  $transaction = $this->connection
    ->startTransaction();
  try {
    $sql = (string) $this;

    }
  } catch (\Exception $e) {

    // One of the INSERTs failed, rollback the whole batch.
    $transaction
      ->rollBack();

    // Rethrow the exception for the calling code.
    throw $e;
  }

  // Re-initialize the values array so that we can re-use this query.
  $this->insertValues = [];

  // Transaction commits here where $transaction looses scope.
