How do you use Phalcon’s PhalconMvcModelQueryLang class?

Answer: Phalcon’s `PhalconMvcModelQueryLang` class is used to construct and execute complex queries using a language similar to SQL. To use it, you typically follow these steps:

1. Create an Instance: Instantiate the `Lang` class where you want to construct your query.
2. Define Your Query: Use methods to define your query parameters, such as `select`, `from`, `where`, etc.
3. Execute the Query: Call the `execute()` method to run the query against the database.
4. Fetch Results: Process the results returned by the query.

Here’s a basic example:

“`php
use PhalconMvcModelQueryLang;

// Create a Lang query
$query = new Lang(“SELECT FROM Robots”);

// Execute the query
$result = $query->execute();

// Fetch results
foreach ($result as $robot) {
echo $robot->name;
}
“`

Make sure to handle exceptions and check for query errors as needed.
