Inner SELECT can't use `u.id` which is in outer SELECT - mysql

I have the following MySQL query:
SELECT
COUNT(b.`id`) AS todayOverdue,
DATE_FORMAT(t.`created_time`, "%Y%m%d") AS days
FROM
`Bill` b
LEFT JOIN `Order` o ON b.`order_id` = o.`id`
LEFT JOIN `Trade` t ON o.`trade_id` = t.`id`
LEFT JOIN `User` u ON b.`user_id` = u.`id`
WHERE
b. `deadline` <= "' . $todayTime . '"
AND b. `deadline` >= "' . $todayDate . '"
AND b.`is_paid` = 0
AND (
SELECT
COUNT(b2.`id`)
FROM
`Bill` b2
WHERE
b2.`deadline` <= "' . $todayTime . '"
AND b2.`user_id` = u.`id`
AND b2.`is_paid` = 0
OR (
b2.`deadline` <= b2.`paid_time`
AND b2.`is_paid` = 1
)
) < 2
GROUP BY
days
Why can't the inner SELECT use u.id which is in outer SELECT?


The inner select is completely independent of the outer select. The u table is being joined in the outer select in ways that are unknown to the inner select.
When you have
AND b2.`user_id` = u.`id`
Which row in u is being compared to which row in b2? The server has no way of knowing, so you need to define a table u2 and join it in the inner select.

sub query inside mysql check value from main table gives error of undefine veriable

my query is like below
SELECT

LEFT JOIN
(
SELECT *
FROM
(
SELECT *
FROM _map_contacts as t
LEFT JOIN contact_master as c on c.contact_id = t.contact_id

limit 1
) tm LEFT JOIN contactdetail_master cd ON cd.contactdetail_id = tm.contactdetail_id
) b ON b.agreement_id = a.curr_tenant_agreement_id
it gives me error of a.punit_id is undefine
how can I use mail table value in left join inside sub query

SELECT
*
FROM `punit_master` `a`
LEFT JOIN
(
SELECT *
FROM
(
SELECT *
FROM _map_contacts as t
LEFT JOIN contact_master as c
ON c.contact_id = t.contact_id

Try this! :)

subquery returns more than 1 row?

subquery returns more than 1 row ? sulution ?
SELECT `t_files`.*, `t_users`.`username`,
(SELECT CONCAT(b.first_name, " ", b.last_name)
FROM t_files AS a
JOIN t_users as b
ON b.id = a.user_id
) as upload_by
FROM `t_files`
LEFT JOIN `t_files_permission`
ON `t_files_permission`.`id_files` = `t_files`.`file_id`
LEFT JOIN `t_users`
ON `t_users`.`id` = `t_files_permission`.`id_users`
WHERE `t_files`.`company_id` = '1'
AND `t_files_permission`.`id_users` = '59'
AND `is_deleted` =0

Add the condition in your sub query like below
SELECT t_files.*, t_users.username,
(SELECT CONCAT(b.first_name, " ", b.last_name)
FROM t_files AS a
JOIN t_users AS b ON b.id = a.user_id
WHERE a.id_users` = '59'
) as upload_by
FROM t_files
LEFT JOIN t_files_permission ON t_files_permission.id_files = t_files.file_id
LEFT JOIN t_users ON t_users.id = t_files_permission.id_users
WHERE t_files.company_id = '1' AND t_files_permission.id_users = '59' AND is_deleted =0

try this way
SELECT `t_files`.*, `t_users`.`username`,
(select CONCAT(b.first_name, " ", b.last_name)
from t_files as a
join t_users as b on b.id = a.user_id
where t.files.id=a.id) as upload_by
FROM `t_files` as
LEFT JOIN `t_files_permission` ON `t_files_permission`.`id_files` = `t_files`.`file_id`
LEFT JOIN `t_users` ON `t_users`.`id` = `t_files_permission`.`id_users`
WHERE `t_files`.`company_id` = '1' AND `t_files_permission`.`id_users` = '59' AND `is_deleted` =0
I think you don't need sub query. You can use join to resolve stuff.

MYSQL Update AND SUM

i am try to do somethink like this
UPDATE BA C
INNER JOIN
(
SELECT SUM(`Amount`) AS `LSC`,`To` FROM `Trans`
) A ON C.`UserID` = A.`To`
INNER JOIN
(
SELECT SUM(`Amount`) AS `LSC`,`From` FROM `Trans`
) B ON C.`UserID` = B.`From`
SET `Bal` = A.`LSC` - B.`LSC`;
and this is not workink :\
when i just do 1 inner join and run the query twice once to A and second to be it work but i want to do it in one query ...
UPDATE BA C
INNER JOIN
(
SELECT SUM(`Amount`) AS `LSC`,`To` FROM `Trans`
) A ON C.`UserID` = A.`To`
SET `Bal` = A.`LSC`; // Work

MS ACCESS- Editing and undoing SQL causes error

I have a query (equivalent of View in ORACLE, SQL Server) that I saved in an Access database. Now I need to add another column to my select list. But whenever I change the SQL I get errors. Let's say I remove one comma and then put it back. I get errors like "Syntax error after From","Syntax error in Join operation". So if I change anything and then undo the change I still get errors. How can I avoid this?

By the way, it worked in MS Access 2010. Mine is Access 2003

What has happened is that your subquery or derived table is now bracketed like so
[stuff here].
This causes an error when editing.
The easiest thing to do is use notepad or such like, replace []. with () and paste back.

Limits a left join?

Hi I have a query that pulls the results from a search but I want the left joined results to be limited to 1
Here is the left join:
LEFT JOIN #__ezrealty_siteplan AS sp ON sp.listing_id = a.id "
What I have tried
LEFT JOIN (SELECT * FROM jos_ezrealty LEFT JOIN jos_ezrealty_siteplan AS sp ON (sp.listing_id =jos_ezrealty.id ) LIMIT 1) AS sp ON (sp.listing_id=jos_ezrealty.id)
The entire query:
$query="SELECT a.*, cc.name AS category, ee.ezcity AS proploc, dd.name AS statename, bb.name AS countryname,
u.logo_image AS logo_image, u.mid AS mid, u.dealer_name AS dealer_name, u.dealer_company AS dealer_company,
u.dealer_phone AS dealer_phone, u.dealer_mobile AS dealer_mobile, u.published AS dealerpublished, sp.tenant AS tenant, sp.spacenum AS spacenum, sp.sf AS sf, sp.image AS tenantimage,
u.dealer_type AS dealer_type FROM #__ezrealty as a"
. "\n LEFT JOIN #__ezrealty_catg AS cc ON cc.id = a.cid"
. "\n LEFT JOIN #__ezrealty_locality AS ee ON ee.id = a.locid"
. "\n LEFT JOIN #__ezrealty_state AS dd ON dd.id = a.stid"
. "\n LEFT JOIN #__ezrealty_country AS bb ON bb.id = a.cnid"
. "\n LEFT JOIN #__ezrealty_profile AS u ON u.mid = a.owner"
. "\n LEFT JOIN #__ezrealty_siteplan AS sp ON sp.listing_id = a.id "
. "\n WHERE $extrastring AND a.published = '1' $vacant AND cc.access <= $my->gid $wheres "
. $order.' LIMIT '.$pageNav->limitstart.', '.$pageNav->limit;

In SQL Server, you could use CROSS APPLY. In other DBMS, you can use partitioning (windowing function ROW_NUMBER).
For MySQL, one solution is to use a subquery to get LIMIT 1, then join that to the table, e.g.
select a.col1, a.col2, a.col3, b.col1, b.col2
from
(
select a.col1, a.col2, a.col3, (select b.id as b_id from tbl_b b where b.a_id=a.id limit 1)
from tbl_a a
) a
left join tbl_b b on b.id=a.b_id

I thinks this will give you what you want
SELECT DISTINCT sp.id ,* FROM jos_ezrealty LEFT JOIN jos_ezrealty_siteplan AS sp ON sp.listing_id =jos_ezrealty.id

LEFT JOIN ( SELECT *
FROM #__ezrealty_siteplan
GROUP BY listing_id )
AS sp
ON sp.listing_id = a.id
