OResultSet

This class provides an interface for operating on data returned by OrientDB queries and commands.

Managing Result-sets

Whenever you issue a query or command to an OrientDB database, (through the ODatabaseDocument class, for instance), OrientDB returns results as an OResultSet instance. You can then operate on this instance to retrieve data or further process it before returning it to the user.

To use OResultSet, you need to import it to your code.

import com.orientechnologies.orient.core.sql.executor.OResultSet;

Once you've imported it, you can set variables with this class and retrieve results.

Example

private ODatabaseDocument db;
...

// Return Count of Accounts 
public long fetchAccountCount(){

	// Fetch Data
	OResultSet data = db.query("SELECT FROM Accounts");

	return data.elementStream().count();
}
