select 数据如何从表中打印出来

Question

I looked but now nothing, there is some way to select something from a table.

For example:

two text boxes number1 and number2 and enter 10 and 20, then print all records in a table from register 10 to 20.

It is possible to do with

$query = "SELECT * FROM crm_vendas WHERE venda_id BETWEEN 'number1' and '$ number2'";

and also with

while ($ row =?

if someone can indicate something or help I would appreciate it

Answer 1

You need to use prepared statements. Also, you do not put backticks around the entire query line. The i's in the bind_param line indicated that the two variables you're using are integers.

    $number1 = 0;
    $number2 = 100;
    $query = "SELECT * FROM crm_vendas WHERE venda_id BETWEEN ? AND ?";
    $stmt = $db->prepare($query);
    $stmt->bind_param('ii', $number1, $number2);
    $stmt->execute();
    $result = $stmt->get_result();

    echo '<table>';
    while ($row = $result->fetch_row()) {
        echo '<tr>';
        foreach($row as $columnValue){
            echo '<td><p>'.$columnValue.'</p></td>';
        }
        echo '</tr>';
    }
    echo '</table>';

    $result->close();
    $stmt->close();
