MySQL Union无法正常工作

Question

I have tables:

Streams:

+----+-------------------+------------+
| id | channel           | bouquet    |
+----+-------------------+------------+
|  1 | USA_CH 1          | ["1","28"] |
|  2 | USA_CH 2          | ["1","28"] |
| 11 | USA_CH 3          | ["1"]      |
| 12 | USA_CH 4          | ["28"]     |
+----+-------------------+------------+

Channels:

+----+--------------------------+---------+----------+
| id | sort                     | bouquet | reseller |
+----+--------------------------+---------+----------+
|  1 | ["m1","1","2","m2","11"] | ["1"]   |        0 |
| 27 | ["1","2"]                | ["28"]  |        0 |
| 39 | []                       | ["33"]  |        0 |
+----+--------------------------+---------+----------+

Markers:

+----+--------+-------+---------+----------+
| id | marker | title | bouquet | reseller |
+----+--------+-------+---------+----------+
|  1 | m1     | MEGA  |       1 |        1 |
+----+--------+-------+---------+----------+
|  2 | m2     | XTRA  |       1 |        1 |
+----+--------+-------+---------+----------+

And need to get channels order with marker from channels table sort field:

["m1","1","2","m2","11"]

So i need to get output like this:

+----+-------------------+
| id | channel           |
+----+-------------------+
|  1 | MEGA              |
|  1 | USA_CH 1          |
|  2 | USA_CH 2          |
|  2 | XTRA              |
| 11 | USA_CH 3          |
+----+-------------------+

I try using union SQL:

SELECT s.id, s.channel, m.title FROM streams s, markers m, channels c WHERE JSON_SEARCH(s.bouquet, 'one', '1') IS NOT NULL AND 
JSON_SEARCH(c.bouquet, 'one', '1') IS NOT NULL AND JSON_SEARCH(c.sort, 'one', s.id) IS NOT NULL
UNION 
SELECT s.id, s.channel, m.title FROM streams s, markers m, channels c WHERE JSON_SEARCH(c.sort, 'one', m.marker) IS NOT NULL AND
JSON_SEARCH(s.bouquet, 'one', '1') IS NOT NULL;

And i get this:

 +----+----------+-------+
  | id | channel  | title |
  +----+----------+-------+
  |  1 | USA_CH 1 | MEGA  |
  |  2 | USA_CH 2 | MEGA  |
  | 11 | USA_CH 3 | XTRA  |
  +----+----------+-------+

And i need to get this:

+----+-------------------+
| id | channel           |
+----+-------------------+
|  1 | MEGA              |
|  1 | USA_CH 1          |
|  2 | USA_CH 2          |
|  2 | XTRA              |
| 11 | USA_CH 3          |
+----+-------------------+

What i have done wrong? I read on mysql manual that UNION is for merging two tables values into one...so i was thinking that i will get this result that i need but as you see in my example code i get always from each table each row value..and needs to be value after value corresponding to channels.sort json value...i im building channel ediotor in html5 so i need to get ordering of channels and reading channels name and markers as defined in channels.sort.

Answer 1

I finally did it! Yupiiiii.... :)

SELECT id, sort, channel FROM
(
SELECT s.id, c.sort, s.channel FROM streams s, channels c
WHERE JSON_SEARCH(s.bouquet, 'one', '1') IS NOT NULL AND
JSON_SEARCH(c.bouquet, 'one', '1') IS NOT NULL AND JSON_SEARCH(c.sort, 'one', s.id) IS NOT NULL
UNION
SELECT m.marker, c.sort, m.channel FROM markers m, channels c, streams s
WHERE JSON_SEARCH(m.bouquet, 'one', '1') IS NOT NULL AND
JSON_SEARCH(c.bouquet, 'one', '1') IS NOT NULL AND JSON_SEARCH(c.sort, 'one', m.marker) IS NOT NULL
) A
ORDER BY LOCATE(id, CONCAT("'", sort, "'"));

And i got nice output:

+----+--------------------------+----------+
| id | sort                     | channel  |
+----+--------------------------+----------+
| m1 | ["m1","1","2","m2","11"] | MEGA     |
| 1  | ["m1","1","2","m2","11"] | USA_CH 1 |
| 2  | ["m1","1","2","m2","11"] | USA_CH 2 |
| m2 | ["m1","1","2","m2","11"] | XTRA     |
| 11 | ["m1","1","2","m2","11"] | USA_CH 3 |
+----+--------------------------+----------+

Thanks guys for commenting above example that my single query in UNION is wrong..using detail try and error i got it finally..so if someone needs code here is it
