What are the advantages of using Views in Oracle databases to handle column aliases and table names in SQL queries generated by PHP?

When using PHP to generate SQL queries for Oracle databases, it can be cumbersome to handle column aliases and table names within the queries. One way to simplify this process is by creating Views in the Oracle database that define the desired column aliases and table names. By referencing these Views in the PHP-generated queries, developers can streamline the code and make it more readable. 

<?php
// Connect to Oracle database
$conn = oci_connect('username', 'password', 'localhost/XE');

// Create a View with column aliases and table names
$sql = "CREATE VIEW my_view AS
        SELECT column1 AS alias1, column2 AS alias2
        FROM my_table";
$stid = oci_parse($conn, $sql);
oci_execute($stid);

// Generate SQL query using the View
$query = "SELECT alias1, alias2
          FROM my_view
          WHERE condition = 'value'";

// Execute the query
$stid = oci_parse($conn, $query);
oci_execute($stid);

// Fetch results
while ($row = oci_fetch_assoc($stid)) {
    // Process results
}

// Close connection
oci_close($conn);
?>
