What are the limitations of using odbc queries in PHP for data navigation?

One limitation of using ODBC queries in PHP for data navigation is that it can be inefficient and slow when dealing with large datasets. To improve performance, you can limit the number of rows returned by the query using the SQL LIMIT clause. 

// Connect to the database
$dsn = "odbc:Driver={ODBC Driver 17 for SQL Server};Server=myServerAddress;Database=myDataBase;";
$username = "myUsername";
$password = "myPassword";
$conn = new PDO($dsn, $username, $password);

// Query with LIMIT clause to limit the number of rows returned
$query = "SELECT * FROM myTable LIMIT 10";
$stmt = $conn->query($query);

// Fetch and process the results
while ($row = $stmt->fetch()) {
    // Process each row
}

// Close the connection
$conn = null;
