Question

I have two tables with a single common field.
Here is how these two table structures are

Table 1

+--ID--+--Title----+----others---+
| 123  | Title 1   | other values|
| 124  | Title 2   | other values|
| 125  | Title 3   | other values|
| 126  | Title 4   | other values|
+------+-----------+-------------+

Table 2

+--ID--+--Tag ID--+----others---+
| 123  |   11     | other values|
| 123  |   12     | other values|
| 123  |   13     | other values|
| 123  |   14     | other values|
| 124  |   15     | other values|
| 124  |   16     | other values|
| 125  |   17     | other values|
| 126  |   18     | other values|
+------+----------+-------------+

I want to show that Article ID 123 have 4 tags i.e 11,12,13 & 14 like the table below

+--Article ID--+--Article Title--+--Tags--+--Tag IDs------+
|     123      |    Title 1      |    4   | 11, 12, 13, 14|
|     124      |    Title 2      |    2   |     15, 16    |
|     125      |    Title 3      |    1   |        17     |
|     126      |    Title 4      |    1   |        18     |
+--------------+-----------------+--------+---------------+

I’m very new to PHP and MySQL and trying to learn it.

Someone please help me to know how I can get the desired result.

Answer 1

SELECT t1.id AS 'Article ID',
t1.title AS 'Article Title', 
count( t2.tag_id ) AS 'Tags', 
GROUP_CONCAT( t2.Tag_Id order by t2.Tag_id ASC) AS `Tag IDs`
FROM table1 t1
JOIN table2 t2 ON ( t1.id = t2.id )
GROUP BY t1.id;

Hope this works!
