book_author Richard Benjamin                


book_name                       book_page   book_price  book_published_date book_topic

我需要 SQL 查询。我需要选取一行(book_author)和其他关联行。

谢谢

Answer 1

<?php
    $sqlAuthor = "SELECT DISTINCT book_author FROM book_name";
    $exeAuthor = mysql_query($sqlAuthor);
    if($exeAuthor)
    {
        while($dataAuthor = mysql_fetch_assoc($exeAuthor))
        {
            $sqlBookRec = "SELECT * FROM book_name where book_author='".$dataAuthor['book_author']."'";
            $exeBookRec = mysql_query($sqlBookRec);
            if($exeBookRec)
            {
                echo "Book Author: ".$dataAuthor['book_author'];
                while($dataBookRec = mysql_fetch_assoc($exeBookRec))
                {
                    echo "Book Name".$dataBookRec['book_name'];
                }
            }
        }
    }
?>

试试这个。希望它能发挥作用。
