Represent a Cloud Spanner lookup result (either read or executeSql).

$database = $spanner->connect('my-instance', 'my-database');

Return the session associated with the result stream.

Get the query plan and execution statistics for the query that produced this result set.

By default, statistics are returned by default only when executing a DML statement. To receive statistics for a SELECT statement, set $options.queryMode to Result::MODE_PROFILE, as demonstrated below.

Setting $options.queryMode to Result::MODE_PLAN will return the query plan without any results or execution statistics information.

Example:

$stats = $result->stats();

// Executing a query with stats returned.
use Google\Cloud\Spanner\Result;

$res = $database->execute('SELECT * FROM Posts', [
    'queryMode' => Result::MODE_PROFILE
]);

Returns a snapshot which was begun in the read or execute, if one exists.

Will be populated once the result set is iterated upon.

Example:

$snapshot = $result->snapshot();

Returns a transaction which was begun in the read or execute, if one exists.

Will be populated once the result set is iterated upon.

Example:

$transaction = $result->transaction();
