What specific database query is being executed in the function?

The specific database query being executed in the function is a SELECT query to retrieve data from a database table. This query is likely fetching specific information based on certain criteria such as a user ID or a product name. To solve this issue, we need to ensure that the query is properly constructed with the necessary parameters and that the connection to the database is established before executing the query. 

// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Construct and execute the database query
$user_id = 123;
$sql = "SELECT * FROM users WHERE id = $user_id";
$result = $conn->query($sql);

// Process the query result
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"]. " - Email: " . $row["email"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close the database connection
$conn->close();
