Question

如何在MySql查询中选择除前三行之外的所有行？

$query = mysql_query("SELECT * FROM comments WHERE approved = 1");

Answer 1

您想要以下内容：

$query = mysql_query("SELECT * FROM comments WHERE approved = 1");
$rowCount = 0;
while ($row = mysql_fetch_assoc($query)) {
    $rowCount = $rowCount + 1;
    // do stuff only if you have reached the third row.
    if ($rowCount > 3){
        // do stuff here
    }
}

Answer 2

SELECT * FROM comments WHERE approved = 1 LIMIT 3,SOME_HUGE_NUMBER

Answer 3

$query = mysql_query("SELECT * FROM comments
                                     WHERE approved = 1 
                                     ORDER BY columnName 
                                     LIMIT 3");

要按columnName使用

查找第三个记录顺序

$query = mysql_query("SELECT * FROM comments
                                     WHERE approved = 1 
                                     ORDER BY columnName 
                                     LIMIT 2, 1");

要查找除前3行以外的所有内容，请使用LIMIT 2, total_no_of_rows

如果你不知道total_no_of_rows使用非常大的数字而不是它。

$query = mysql_query("SELECT * FROM comments
                                     WHERE approved = 1 
                                     ORDER BY columnName 
                                     LIMIT 2, total_no_of_rows");

在mysql中选择一系列值
