嗨,我将sql查询结果存储在数据库中。我必须检查是否有任何行包含字符串'N;'。然后下一个sql语句应该执行。我有很多这样的字符串,这就是为什么要执行我的下一个sql语句。我已经尝试了以下代码,但是当我尝试运行该代码时,它会进入无限循环。谢谢。这是我的PHP代码:
while ($row = mysql_fetch_assoc($result)) {
$config= $row['configuration'];
if($config=='N;')
{
$sql="SELECT DISTINCT ad_news_texte.id, ad_news_texte.headline, ad_news.datum_archiv FROM autodo.ad_news_texte INNER JOIN autodo.ad_news_oe ON ad_news_texte.news_id = ad_news_oe.id_ad_news INNER JOIN autodo.ad_news ON ad_news_oe.id_ad_news = ad_news.id WHERE ad_news.datum_archiv BETWEEN curdate( ) - INTERVAL DAYOFWEEK( curdate( ) ) +28 DAY AND curdate( )";
$result = mysql_query($query, $myConnection);
}
else{
$html .= '<table id="news">
<a href="news.php?id=">
<p class="welcome-subheadline"> '. $config .'</p></a>
</table>';
}
}
好的,所以我想念一些信息,但是我将尝试通过以下两种方法来解决您的问题:
如果您的sql提取与循环中的sql语句相同,则代码应如下所示:(在这种情况下,我看不到if语句的原因)
$sql="SELECT DISTINCT ad_news_texte.id, ad_news_texte.headline, ad_news.datum_archiv FROM autodo.ad_news_texte INNER JOIN autodo.ad_news_oe ON ad_news_texte.news_id = ad_news_oe.id_ad_news INNER JOIN autodo.ad_news ON ad_news_oe.id_ad_news = ad_news.id WHERE ad_news.datum_archiv BETWEEN curdate( ) - INTERVAL DAYOFWEEK( curdate( ) ) +28 DAY AND curdate( )";
$result = mysql_query($sql, $myConnection);
while ($row = mysql_fetch_assoc($result)) {
$config= $row['configuration'];
if($config=='N;')
{
// If the sql is the same no need for another fetch
}
else{
$html .= '<table id="news">
<a href="news.php?id=">
<p class="welcome-subheadline"> '. $config .'</p></a>
</table>';
}
}
在第二种情况下,当sql语句不同时,代码应如下所示:
$result = mysql_query($sql, $myConnection);
while ($row = mysql_fetch_assoc($result)) {
$config= $row['configuration'];
if($config=='N;')
{
$sql2="SELECT DISTINCT ad_news_texte.id, ad_news_texte.headline, ad_news.datum_archiv FROM autodo.ad_news_texte INNER JOIN autodo.ad_news_oe ON ad_news_texte.news_id = ad_news_oe.id_ad_news INNER JOIN autodo.ad_news ON ad_news_oe.id_ad_news = ad_news.id WHERE ad_news.datum_archiv BETWEEN curdate( ) - INTERVAL DAYOFWEEK( curdate( ) ) +28 DAY AND curdate( )";
$result2 = mysql_query($sql2, $myConnection);
while ($row2 = mysql_fetch_assoc($result2)) {
//The rest of the code
}
}
else{
$html .= '<table id="news">
<a href="news.php?id=">
<p class="welcome-subheadline"> '. $config .'</p></a>
</table>';
}
}
