Question

我正在使用查询来搜索两个表格（曲目和艺术家）：

SELECT trackID, title
FROM tracks WHERE title LIKE '%$s%'
LIMIT 5
UNION
SELECT artistID, name
FROM artists WHERE name LIKE '%$s%'
LIMIT 5";

我使用mysql_num_rows($result)来显示此查询的结果，但我不知道如何正确显示它。因为当行来自艺术家但保持相同的顺序时，我希望输出结果不同。

我希望这很清楚，在此先感谢!!

您可以使用其他列来标识结果行，例如

SELECT trackID AS id, title AS title, 'track' AS result_type
FROM tracks WHERE title LIKE '%$s%'
LIMIT 5
UNION
SELECT artistID AS id, name AS title , 'artist' AS result_type
FROM artists WHERE name LIKE '%$s%'
LIMIT 5;

/* $result= fetch results from query*/
   foreach($result as $row){
     if($row['result_type'] =='track'){
    /*  your code */
     }
     if($row['result_type'] =='artist'){
    /* your code */
     }
   }

MYSQL联合显示
