php - MYSQL联合展示

Question

我正在使用查询在两个表(轨道和艺术家)中进行搜索:

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

我使用 mysql_num_rows($result) 来显示这个查询的结果，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顺序时，我希望输出结果不同。

我希望这是清楚的，提前致谢!!

Answer 1

您可以使用另一列来标识结果行，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 */
     }
   }
