Question

<?php

   if (!$con = mysql_connect('localhost', 'root', 'password')) {
   die('An error occurred while connecting to the MySQL server!<br><br>' . 
   mysql_error());
 }

 if (!mysql_select_db('mydb')) { die('An error occurred while connecting 
 to the database!<br><br>' . mysql_error()); }

// Create an array of MySQL queries to run
  $sql = array( 'DROP TABLE IF EXISTS appengage.updateon;', 'CREATE TABLE 
   appengage.updateon SELECT start_date, updated_on FROM mydb.issues 
   WHERE start_date BETWEEN DATE_SUB(NOW(), INTERVAL 3 Day) AND NOW();'
  );

// Run the MySQL queries
if (sizeof($sql) > 0) {
foreach ($sql as $query) {
    if (!mysql_query($query)) {
        die('A MySQL error has occurred!<br><br>' . mysql_error());
    }
}
}
?>

以上代码给出了在过去3天内更新过的记录，但我希望这些记录在过去3天内未更新。

通过这种方式更改代码：

// Create an array of MySQL queries to run
  $sql = array( 'DROP TABLE IF EXISTS appengage.updateon;', 'CREATE TABLE 
   appengage.updateon SELECT start_date, updated_on FROM mydb.issues 
   WHERE start_date NOT BETWEEN DATE_SUB(NOW(), INTERVAL 3 Day) AND NOW();'
  );

我在NOT

之前添加了BETWEEN DATE_SUB
