Hello,
I need to select data from 3 table simultaneously in one query and i can't get iti work...please help if you can. Thanks in advance!
my tables:
mysql> describe produse_ofertate;
+-------------+-----------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-----------------+------+-----+---------+----------------+
| id | int(6) unsigned | NO | PRI | NULL | auto_increment |
| id_oferta | int(11) | NO | | NULL | |
| nume_produs | varchar(300) | NO | | NULL | |
+-------------+-----------------+------+-----+---------+----------------+
3 rows in set (0.00 sec)
mysql> describe produse_cantitate;
+-----------+-----------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+-----------------+------+-----+---------+----------------+
| id | int(6) unsigned | NO | PRI | NULL | auto_increment |
| id_oferta | int(11) | NO | | NULL | |
| cantitate | int(11) | NO | | 0 | |
+-----------+-----------------+------+-----+---------+----------------+
3 rows in set (0.00 sec)
mysql> describe produse_pret;
+-----------+-----------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+-----------------+------+-----+---------+----------------+
| id | int(6) unsigned | NO | PRI | NULL | auto_increment |
| id_oferta | int(11) | NO | | NULL | |
| pret | decimal(8,2) | NO | | NULL | |
+-----------+-----------------+------+-----+---------+----------------+
3 rows in set (0.00 sec)
This is what I have in tables:
mysql> SELECT produse_ofertate.nume_produs FROM produse_ofertate WHERE produse_ofertate.id_oferta = 4;
+-------------+
| nume_produs |
+-------------+
| aaaaa |
| dsaddas |
| asasa |
| dddd |
+-------------+
4 rows in set (0.00 sec)
mysql> SELECT produse_cantitate.cantitate FROM produse_cantitate WHERE produse_cantitate.id_oferta = 4;
+-----------+
| cantitate |
+-----------+
| 2 |
| 1 |
| 1 |
| 1 |
+-----------+
4 rows in set (0.00 sec)
mysql> SELECT produse_pret.pret FROM produse_pret WHERE produse_pret.id_oferta = 4 ;
+-------+
| pret |
+-------+
| 80.00 |
| 76.00 |
| 54.00 |
| 36.00 |
+-------+
4 rows in set (0.00 sec)
And this is the best result I could get, but it only returns 2 values for "cantitate" (there are 4), and all data is on a single columns and it should be on separate columns...
mysql> (SELECT produse_ofertate.nume_produs FROM produse_ofertate WHERE produse_ofertate.id_oferta = 4) UNION (SELECT produse_cantitate.cantitate FROM produse_cantitate WHERE produse_cantitate.id_oferta = 4) UNION (SELECT produse_pret.pret FROM produse_pret WHERE produse_pret.id_oferta = 4);
+-------------+
| nume_produs |
+-------------+
| aaaaa |
| dsaddas |
| asasa |
| dddd |
| 2 |
| 1 |
| 80.00 |
| 76.00 |
| 54.00 |
| 36.00 |
+-------------+
10 rows in set (0.01 sec)
I need 3 columns: nume_produs, cantitate and pret, in a single table. If you can help me, please do. Thanks!
