What potential issues could arise when using the BETWEEN clause in SQL queries?

One potential issue that could arise when using the BETWEEN clause in SQL queries is that it may not include the upper bound value in the results. To ensure that the upper bound value is included, you can adjust the query to use the greater than or equal to (>=) and less than or equal to (<=) operators instead. 

// Adjust the query to use &gt;= and &lt;= operators to include the upper bound value
$sql = &quot;SELECT * FROM table_name WHERE column_name &gt;= lower_bound AND column_name &lt;= upper_bound&quot;;
$result = mysqli_query($connection, $sql);

// Process the result set
if (mysqli_num_rows($result) &gt; 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process each row
    }
} else {
    echo &quot;No results found.&quot;;
}
