In the context of the forum thread, what best practices can be recommended for structuring database queries to avoid displaying duplicate data in separate tabs?

When displaying data from a database in separate tabs, it is important to structure your database queries in a way that avoids displaying duplicate data. One way to achieve this is by using a DISTINCT clause in your SQL query to ensure that only unique records are retrieved. Additionally, you can use JOIN statements to combine related tables and avoid redundant data.

// Example SQL query with DISTINCT clause and JOIN statement
$query = "SELECT DISTINCT column_name FROM table1
          JOIN table2 ON table1.id = table2.id
          WHERE condition = 'value'";
$result = mysqli_query($connection, $query);

// Display data from query results
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'];
}
