I am having trouble in getting unique result from my query. The query mentioned here displays duplicate values 6 times instead of giving an unique answer. How can I get the result only once?
SELECT step1 . * , TIME_FORMAT( step2.insert_time, '%H:%i:%s' ) AS insert_time,
DATE_FORMAT( step2.insert_time, '%d-%b-%Y %h:%i:%s' ) tradate, b.batch_name,

INNER JOIN csm_class c ON c.class_code = ClassID

I have a query that is giving me different results when i enclosed it in Parentheses, however when I run it without Parentheses its giving me different results. I want to apply Union in between so I have to use Parentheses as without union doesn't work.
The query is as follows:
SELECT Distinct

Same query if enclosed in Parentheses will give me different results.
Parentheses are not required for a UNION statement. The following 2 union statements both work and yield the same results.
SELECT 1 UNION SELECT 2;
(SELECT 1) UNION (SELECT 2);
I can't find solution to correct this big query, I always receive an error from database.
I have tre tables and I need to make changes on some attribute on some condition:
UPDATE o36t_orders as temp1,
mytable as temp2
SET
temp1.bonifico = 1,
temp2.ultimo = 1
WHERE
temp1.id_order IN (
SELECT
id_order
FROM o36t_orders
LEFT JOIN o36t_address ON (o36t_address.id_address = o36t_orders.id_address_delivery)
LEFT JOIN mytable ON (
mytable.Causale = CONCAT(
o36t_address.lastname,
' ',
o36t_address.firstname
)
)
WHERE
o36t_orders.bonifico <> 1
)
AND temp2.id IN (
SELECT
id
FROM o36t_orders
LEFT JOIN o36t_address ON (o36t_address.id_address = o36t_orders.id_address_delivery)
LEFT JOIN mytable ON (
mytable.Causale = CONCAT(
o36t_address.lastname,
' ',
o36t_address.firstname
)
)
WHERE
o36t_orders.bonifico <> 1
)
Since the subqueries of the 2 IN clauses are identical (except the retuned column), I think that you can do what you want by a straight inner join of the 2 tables and that subquery (returning both columns):
UPDATE o36t_orders temp1
INNER JOIN (
SELECT
id, id_order
FROM o36t_orders
LEFT JOIN o36t_address ON (o36t_address.id_address = o36t_orders.id_address_delivery)
LEFT JOIN mytable ON (
mytable.Causale = CONCAT(
o36t_address.lastname,
' ',
o36t_address.firstname
)
)
WHERE
o36t_orders.bonifico <> 1
) t ON t.id_order = temp1.id_order
INNER JOIN mytable temp2 ON temp2.id = t.id
SET
temp1.bonifico = 1,
temp2.ultimo = 1

You are using inner join so if there are matching records then only result will be returned for 2017. Why dont you use left join and try the same
I have a principal requet with 2 requets in. I have a problem in my second nested query, I have a condition on id and if I made my request id = 10 takes a long time to execute, so if I replace it by id LIKE 10 my request execute in one second.
Here the request:

the line is the following problem toto.project.id_project = '10' and I don't understand why the time to execute request is so different between = and LIKE
Let's start with your subquery. Those 17 lines that you've written are functionally identical to this, so why not use this instead?
SELECT DISTINCT g.id_contact_groupe
FROM contact_groupe g
JOIN project p
ON p.id_contact_groupe = g.id_contact_groupe
WHERE g.en_attente = 0
AND p.id_project = 10

The following query on my MySQL tables returns rows from the purchaseorder table that have corresponding entries in the deliveryorder table. How do I construct this query so that I get rows from the purchaseorder table even if no corresponding rows exist in the deliveryorder table? If the users want to see sql table CREATE statements, I can post those, but I'm not posting now as it really makes the question too big.
SELECT
`purchaseorder`.`id` AS `po_id`,
`purchaseorder`.`order_quantity` AS `po_order_quantity`,

You have an aggregating function but no GROUP BY clause, which is wierd, but anyway - something like this? Oops - edited...
