MYSQL工會顯示

Question

我使用一個查詢兩個表（曲目和藝術家）搜索：

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

我用mysql_num_rows($result)顯示此查詢的結果，但我不知道如何展示它正確。 因爲我希望輸出結果不同，當行來自藝術家，但保持相同的順序。

我希望這是明確的，在此先感謝！

您可以使用另一列識別類似的

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 */ 
    } 
    }
