Impossible d'obtenir la sortie souhaitée dans mysql

Je travaille sur un rapport de projet qui nécessite une sortie difficile d'une seule table.Impossible d'obtenir la sortie souhaitée dans mysql

C'est la structure de la table nommée: daily_visit_expenses

ayant des données comme celui-ci :: enter image description here

maintenant ce que je veux que la sortie est la combinaison de ces trois requêtes en une seule colonne (un nom), les requêtes sont:

SELECT DISTINCT(`cust_1`) FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_1`='Sales' 
SELECT DISTINCT(`cust_2`) FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_2`='Sales' 
SELECT DISTINCT(`cust_3`) FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_3`='Sales'

Je veux obtenir la sortie d'une seule requête qui est la combinaison des trois requêtes ci-dessus dans une seule colonne comme customers qui est DISTINCT.

SQL Export:

CREATE TABLE IF NOT EXISTS `daily_visit_expenses` (
    `id` bigint(20) NOT NULL AUTO_INCREMENT, 
    `user` varchar(255) NOT NULL, 
    `date` date NOT NULL, 
    `status` varchar(50) NOT NULL, 
    `location` varchar(50) NOT NULL, 
    `cust_1` varchar(255) NOT NULL,

    `expenses` bigint(20) NOT NULL DEFAULT '0', 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=15 ; 

INSERT INTO `daily_visit_expenses` (`id`, `user`, `date`, `status`, `location`, `cust_1`, `cust_2`, `cust_3`, `cust_4`, `purpose_1`, `purpose_2`, `purpose_3`, `purpose_4`, `visit_type`, `expenses`) VALUES

@Rinzler: requête s'il vous plaît ... –

Pouvez-vous fournir un fichier dump.sql je pourrais utiliser pour créer/remplir une table similaire sur ma fin, je peux tester mon question? – sberry

@sberry: ajout du vidage sql ... –

Essayez d'utiliser UNION

SELECT DISTINCT(`cust_1`) FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_1`='Sales' 
UNION DISTINCT 
SELECT DISTINCT(`cust_2`) FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_2`='Sales' 
UNION DISTINCT 
SELECT DISTINCT(`cust_3`) FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_3`='Sales';

Edit: Changé pour UNION DISTINCT

Essayez ceci, je pense que ce dont vous avez besoin si je ne l'ai pas mal compris question:

SELECT DISTINCT(`customer`) FROM 
(
SELECT `cust_1` FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_1`='Sales' UNION ALL 
SELECT `cust_2` FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_2`='Sales' UNION ALL 
SELECT `cust_3` FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_3`='Sales')

-2

Cela devrait fonctionner:

SELECT DISTINCT(`cust_1`,`cust_2`,`cust_3`) FROM `daily_visit_expenses` 
WHERE user='sanjay' AND (`purpose_1`='Sales' OR `purpose_2`='Sales' OR 
`purpose_3`='Sales')

L'opérande doit contenir 1 colonne (s) ... –

mysql> SELECT DISTINCT(`customer`) FROM (SELECT `cust_1` as `customer` FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_1`='Sales' UNION ALL SELECT `cust_2` as `customer` FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_2`='Sales' UNION ALL SELECT `cust_3` as `customer` FROM `daily_visit_expenses` WHERE user='sanjay' AND `purpose_3`='Sales') as t; 
+---------------------------------------+ 
| customer        | 
+---------------------------------------+ 
| S.G.R.S. Chemical & Minral Industries | 
| V.N INTERNATIONAL      | 
| G.SURGIWEAR       | 
| fatehpur foundry      | 
+---------------------------------------+ 
4 rows in set (0.00 sec)
