Merging info from two queries into a single table - mysql

Question

Query 1:
SELECT num_requerimiento, asunto
FROM masivos_texto INNER JOIN envios_masivos
ON id_masivos=id_envio;
Result 1:
+---------------------+---------------------+
| num_requerimiento | asunto |
|---------------------+----------------------
| 1800 | inscripcion |
|---------------------+---------------------+
| 1801 | seguimiento |
+---------------------+---------------------+
Query 2:
SELECT id_envio, estatus, count(estatus)
FROM acuses_recibo
WHERE id_envio IN (SELECT id_masivos FROM cati_atencion.masivos_texto WHERE fecha >= '2014-01-01' AND fecha <= '2015-06-16')
GROUP BY id_envio, estatus;
Result 2:
+---------------------+---------------------+----------------------+
| id_envio | estatus | count(estatus) |
|---------------------+--------------------------------------------+
| 84 | 0 | 4031 |
|---------------------+---------------------+----------------------+
| 84 | 1 | 632 |
+---------------------+---------------------+----------------------+
| 85 | 0 | 35635 |
+---------------------+---------------------+----------------------+
| 85 | 1 | 3711 |
+---------------------+---------------------+----------------------+
Desired Result:
+---------------------+-----------------+------------+------------+-------------------+
| num_requerimiento | asunto | id_envio | estatus | count(estatus) |
|---------------------+-----------------+------------+------------+-------------------+
| 1800 | inscripcion | 84 | 0 | 4031 |
|---------------------+-----------------+------------+------------+-------------------+
| 1800 | inscripcion | 84 | 1 | 632 |
+---------------------+-----------------+------------+------------+-------------------+
| 1801 | seguimiento | 85 | 0 | 635 |
+---------------------+-----------------+------------+------------+-------------------+
| 1801 | seguimiento | 85 | 1 | 711 |
+---------------------+-----------------+------------+------------+-------------------+
in the Desired Result the id_envio/id_masivos corresponding to num_requerimiento 1800 is 84,
and the id_envio/id_masivos corresponding to num_requerimiento 1801 is 85,
and estatus in the 2nd table cant take up to three values, than i.a. for your assistance.
UNION doesn´t work, it gives me the 1st table followed by the 2nd, and only if the selects are of the same number of columns.

Answer 1

To do this with SQL, you will need a table relating your masivos_texto and acuses_recibo tables. I suggest you create a table. You could call it req_id or anything suitable. This is often called a JOIN table. It will have this content
num_requerimiento id_envio
1800 84
1801 85
Then you'll be able to join your first and second queries together appropriately.
It's not possible to write your query for you without knowing the rows of your tables.

Answer 2

Solved!! I needed to use aliases to each SELECT, as adding an alias to each select level, like this:
SELECT result1.num_requerimiento, result1.asunto, result1.id_masivos, result2.estatus, result2.conteo
FROM
(SELECT C.num_requerimiento, B.asunto, B.id_masivos
FROM masivos_texto B INNER JOIN envios_masivos C
ON B.id_masivos=C.id_envio) as result1
INNER JOIN
(SELECT A.id_envio, A.estatus, count(estatus) as conteo
from acuses_recibo A
WHERE A.id_envio IN (SELECT B.id_masivos FROM masivos_texto B where B.fecha >= '2014-01-01' AND B.fecha <= '2015-06-16')
GROUP BY A.id_envio, A.estatus) as result2
ON result1.id_masivos=result2.id_envio;
and that generates the 3rd table needed. Hope it helps someone in the future.
