We want to get the 10 best rating movies based on the average of the rating that the movie has. Suppose that we have a collection where we store the reviews for a movie, and the review contains a rating. For that reason, in the next example we are going to create a more complex query that cannot be handled by an XSession object. Of course, the previous example can be accomplished without using a NodeSession object. We access the array object by indexes to get the information we require, in the code we get the value of the column 0 (index 0) to write it in the console. Each item in the array represents a column of a row. Once the query is executed, a result object is received, but in this case, it contains a row returned from the query represented as an array object. Then, we call the executeSql method again, setting a query that may return one record. In this instance, the result object does not contain any useful information other than reporting the success or failure of the operation.
When the query that sets the current database completes, it returns a Result object ( result) that contains information about the execution of the query.
To execute the query, we need to call the execute method. Then we call the nodesession objects’s executeSql method to set the schema that we are going to use. In the previous example, we use the method getNodeSession to get the NodeSession object ( nodesession). Nodesession.executeSql("SELECT * FROM m圜oll LIMIT 1")

The following example demonstrates how to use a NodeSession object. The NodeSession object can be useful, for example, when you want to connect to a specific MySQL server and do operations specifically on this server, or when you want to execute a specific function or create a stored procedure. When you need to execute a query that is not supported by an XSession, use a NodeSession instead.

But there is something that the XSession does not provide, full SQL language support. With it, we can be connected to one or more servers and also give us the required support to work with collections and relational tables. The XSession is a logical session that abstracts our connection. In all the code examples we used the XSession to communicate to the MySQL server. In all the previous blog posts we covered a lot of examples of how to perform actions in a MySQL server set up as a document store.
