<p>In the The query mode of the [[Language Bindings|bindingsClients]], allows you to bind external variables to a query can be sent to and evaluate the server andexecuted query in an iterative manner. For this, you need to call the The <code>query()</code> functionof the <code>Session</code> with your defined query. This will return a query object,which comes with instance returns a forward-only iterator to get each result of the query.Furthermore, variables can be bound to the query using the <code>bind()</code> functionof the new query objectinstance.</p>

<p>The query execution works as follows:</p>

#Create a new session instance with hostname, port, username and password.#Call the <code>query()</code> function of the session with the query as argument your XQuery expression to get your a query object.#Optionally bind variables to the query with one of the <code>bind()</code> functionfunctions.#Initialize query output Optionally bind a value to the context item via <code>initcontext()</code>.#Iterate through the query object with the <code>more()</code> and <code>next()</code> functions. If # As an error occursalternative, an exception is throwncall <code>execute()</code> to get the whole result at a time.# <code>info()</code> gives you information on query evaluation.# <code>options()</code> returns the query serialization parameters.#Close Don't forget to close the query with <code>close()</code>.
