If else in Mysql Update query - mysql

I need a query to update some fields in a table based on count of another field.
Update
bank_sample_map
LEFT JOIN
sample_details ON bank_sample_map.sample_track_id = sample_details.sampletrack_id
LEFT JOIN
order_details ON order_details.sample_detail_id = sample_details.sample_id
LEFT JOIN
test_details ON test_details.test_detail_id = order_details.test_detail_id
SET
bank_sample_map.sample_id = sample_details.sample_id, bank_sample_map.order_id = order_details.order_number,
bank_sample_map.testid = test_details.test_id,bank_sample_map.test_cost = test_details.test_cost
WHERE
bank_sample_map.sample_id IS NULL
AND bank_sample_map.order_id IS NULL
AND bank_sample_map.testid IS NULL
AND (select count(order_number) < 2 from order_details where sample_detail_id = sample_details.sample_id);
If(count(order_number) < 2) I need to update sample_id,order_id,testid,test_cost
Else update sample_id only.
How to change my query to satisfy this condition.

Update sentence with subquery on MySQL

I have the following sentence, that returns the error
Unknown column targets.ID_TARGET in where clause
and I can't find any solution. Could you guys help?
The proposal is update 'sw_automatic' for each row with the value that th subquery provides (0 or 1)
update bt_pry_targets targets
set targets.sw_automatic = (
(
SELECT (CASE WHEN Task.ID_TP_TASKS_GROUPS = 694 THEN '0' ELSE '1' END) AS TYPE_TASK,
Task.ID_TASK FROM bt_tasks AS Task
INNER JOIN bt_pry_cmp_workflows AS BtCmpWorkflows ON (Task.ID_PRY_CMP_WORKFLOW = BtCmpWorkflows.ID_PRY_CMP_WORKFLOW)
INNER JOIN bt_pry_components AS PryComponent ON (PryComponent.ID_PRY_COMPONENT = BtCmpWorkflows.ID_PRY_COMPONENT )
INNER JOIN bt_components AS Component ON (PryComponent.ID_COMPONENT = Component.ID_COMPONENT)
INNER JOIN bt_pry_targets AS PryTarget ON (PryComponent.ID_TARGET = PryTarget.ID_TARGET)
INNER JOIN bt_flows AS Flows ON (Flows.ID_FLOW = Task.ID_FLOW)
WHERE Flows.SW_END_DEPENDENCE = 1
AND PryTarget.ID_TARGET = targets.ID_TARGET
GROUP BY Task.ID_TASK) )
where targets.sw_automatic is null;
In you subquery the column targets.ID_TARGET in not visible
so you could try using you subquery as a join table for updated
update bt_pry_targets targets
inner join (
SELECT (CASE WHEN Task.ID_TP_TASKS_GROUPS = 694 THEN '0' ELSE '1' END) AS TYPE_TASK,
Task.ID_TASK FROM bt_tasks AS Task
INNER JOIN bt_pry_cmp_workflows AS BtCmpWorkflows ON (Task.ID_PRY_CMP_WORKFLOW = BtCmpWorkflows.ID_PRY_CMP_WORKFLOW)
INNER JOIN bt_pry_components AS PryComponent ON (PryComponent.ID_PRY_COMPONENT = BtCmpWorkflows.ID_PRY_COMPONENT )
INNER JOIN bt_components AS Component ON (PryComponent.ID_COMPONENT = Component.ID_COMPONENT)
INNER JOIN bt_pry_targets AS PryTarget ON (PryComponent.ID_TARGET = PryTarget.ID_TARGET)
INNER JOIN bt_flows AS Flows ON (Flows.ID_FLOW = Task.ID_FLOW)
WHERE Flows.SW_END_DEPENDENCE = 1
AND PryTarget.ID_TARGET = targets.ID_TARGET
GROUP BY Task.ID_TASK
) t on t.PryTarget = targets.ID_TARGET
AND targets.sw_automatic is null
set targets.sw_automatic = t.TYPE_TASK

All data not returning from database on SELECT

Could someone please explain to me why the query below isn't returning all the records matching
creator_id = 10895
and then any records which are linked with
staff_id = 10895 in group table?
It's only returning the record matching staff_id = 10895
SELECT
direct_message.*,
IFNULL(direct_message_group.staff_id, 0) as staff_id
FROM `direct_message`
INNER JOIN direct_message_group
ON direct_message_group.chat_id = direct_message.id
INNER JOIN direct_message_thread
ON direct_message_thread.chat_id = direct_message.id
WHERE
(
direct_message.recipient_id = '10895' OR
direct_message.creator_id = '10895'
OR (
direct_message_group.staff_id = '10895'
AND direct_message_group.active = '0')
)
AND direct_message.school_id = '1'
AND direct_message_thread.school_id = direct_message.school_id
GROUP BY direct_message.id
ORDER BY direct_message_thread.inserted DESC
LIMIT 0, 25

OR condition with Joins using cakephp and mysql

Iam searching a keyword in solr and it returns matched resume id's,when I got the result from solr I am searching those documents and getting matched job seekers from my database.
Now my question is have to get the record if it match in documents or in job seekers skills i.e job_seekers.skills column how to write the query..
Here is my existing query..
SELECT *
FROM `job_seekers` AS `JobSeeker`
LEFT JOIN `job_seeker_documents` AS `JobSeekerDocument` ON (`JobSeeker`.`id` = `JobSeekerDocument`.`job_seeker_id` AND `doc_attachment` IN ('1457448773Jan.doc', '1457448764Eric.doc', 'Vijal_Chokshi_Profile.doc', 'Deborah_Project manager_Profile..docx'))
LEFT JOIN `config_work_authorizations` AS `ConfigWorkAuthorization` ON (`JobSeeker`.`work_authorization` = `ConfigWorkAuthorization`.`id`)
LEFT JOIN `employees` AS `Employee` ON (`Employee`.`job_seeker_id` = `JobSeeker`.`id`)
WHERE `JobSeeker`.`company_id` = 11 AND `JobSeeker`.`skills` = 'java' AND `JobSeeker`.`bench_status` IN (0, 1) AND (select count(*) from employee_jobs where `employee_jobs`.`employee_id`=`Employee`.`id` and `employee_jobs`.`job_status` =1 ) = 0 GROUP BY `JobSeeker`.`id` HAVING (COUNT(`JobSeekerDocument`.`id`) > 0 );
you can write or condition in brackets i.e. () like
(`JobSeeker`.`skills` = 'java' OR `JobSeekerDocument`.`skills` = 'java')
In your query
SELECT *
FROM `job_seekers` AS `JobSeeker`
LEFT JOIN `job_seeker_documents` AS `JobSeekerDocument` ON (`JobSeeker`.`id` = `JobSeekerDocument`.`job_seeker_id` AND `doc_attachment` IN ('1457448773Jan.doc', '1457448764Eric.doc', 'Vijal_Chokshi_Profile.doc', 'Deborah_Project manager_Profile..docx'))
LEFT JOIN `config_work_authorizations` AS `ConfigWorkAuthorization` ON (`JobSeeker`.`work_authorization` = `ConfigWorkAuthorization`.`id`)
LEFT JOIN `employees` AS `Employee` ON (`Employee`.`job_seeker_id` = `JobSeeker`.`id`)
WHERE `JobSeeker`.`company_id` = 11
AND (`JobSeeker`.`skills` = 'java' OR `JobSeekerDocument`.`skills` = 'java')
AND `JobSeeker`.`bench_status` IN (0, 1)
AND (select count(*) from employee_jobs where `employee_jobs`.`employee_id`=`Employee`.`id` and `employee_jobs`.`job_status` =1 ) = 0
GROUP BY `JobSeeker`.`id`
HAVING (COUNT(`JobSeekerDocument`.`id`) > 0 );

Mysql subquery for sum all columns in inner Join

I am attempting to get the sum of 12 columns (in same table) in a subquery in an inner join.
Here is a link to my schema :
SqlFiddle
The query I am attempting to use is this:
SELECT
`inventory`.`part_number`,
`inventory`.`qty`,
`inventory`.`description`,
`reorder`.`reorder_point` * '1' `point`,
`inventory`.`cost`,
`vendor`.`name` AS `vendor_name`, SELECT (SUM(`saleshistory`.`Sales_1_Month_Prior`)+SUM(`saleshistory`.`Sales_2_Month_Prior`)+SUM(`saleshistory`.`Sales_3_Month_Prior`)+SUM(`saleshistory`.`Sales_4_Month_Prior`)+SUM(`saleshistory`.`Sales_5_Month_Prior`)+SUM(`saleshistory`.`Sales_6_Month_Prior`)+SUM(`saleshistory`.`Sales_7_Month_Prior`)+SUM(`saleshistory`.`Sales_8_Month_Prior`)+SUM(`saleshistory`.`Sales_9_Month_Prior`)+SUM(`saleshistory`.`Sales_10_Month_Prior`)+SUM(`saleshistory`.`Sales_11_Month_Prior`)+SUM(`saleshistory`.`Sales_12_Month_Prior`) AS TTL
FROM `inventory`
LEFT JOIN `reorder` ON `inventory`.`part_number` = `reorder`.`part_number`
LEFT JOIN `vendor` ON `inventory`.`vendor` = `vendor`.`vendor_id`
INNER JOIN `saleshistory` ON `saleshistory`.`location` = `inventory`.`location` AND `saleshistory`.`part_number` = `inventory`.`part_number`
WHERE `inventory`.`qty` <= `reorder`.`reorder_point`
AND `inventory`.`location` = '99'
AND `reorder`.`reorder_point` != '0'
GROUP BY `inventory`.`part_number`
ORDER BY `vendor`.`name` ASC
When using this query, it returns all the values for all the records not just the rows.

Combine conditions with AND in Mysql ON clause

I have the following query, that I use to filter rows based on software_id and level.
I've put the conditions in the ON-Clause since I still want rows returned, where there are no corresponding rows in the JobadvertsSoftware Table.
SELECT `Jobadvert`.`id` FROM `jobadverts` AS `Jobadvert`
LEFT JOIN `users` AS `User` ON (`Jobadvert`.`user_id` = `User`.`id`)
LEFT JOIN `jobadverts_softwares` AS `JobadvertsSoftware_0` ON
(`Jobadvert`.`id` = 'JobadvertsSoftware_0.jobadvert_id' AND
(`JobadvertsSoftware_0`.`software_id` = '32' AND
`JobadvertsSoftware_0`.`level` IN ('1', 4)))
WHERE `Jobadvert`.`active` = 1 AND `User`.`premium` = '1' AND
Jobadvert`.`department_id` = (5)
GROUP BY `Jobadvert`.`id`
The problem is that it also returns JobadvertsSoftware-rows where level is e.g. 2
Again, if I put that in the WHERE clause it will filter out the rows where there are not JobadvertsSoftware which it shouldn't do.
How can I tell MySQL to return all rows of Jobadvert, where the given software_id AND the level matches or are NULL?
Try this:
SELECT `Jobadvert`.`id`, `JobadvertsSoftware_0`.`level`
FROM `jobadverts` AS `Jobadvert`
LEFT JOIN `users` AS `User` ON (`Jobadvert`.`user_id` = `User`.`id`)
INNER JOIN `jobadverts_softwares` AS `JobadvertsSoftware_0` ON
(`Jobadvert`.`id` = 'JobadvertsSoftware_0.jobadvert_id' AND
(`JobadvertsSoftware_0`.`software_id` = '32' AND
`JobadvertsSoftware_0`.`level` IN ('1', 4)))
WHERE `Jobadvert`.`active` = 1 AND `User`.`premium` = '1' AND
Jobadvert`.`department_id` = (5)
GROUP BY `Jobadvert`.`id`
Saludos!
Try this( it's a bit unclear if some fields are numeric on string, it might be corrected):
SELECT distinct(`Jobadvert`.`id`) FROM `jobadverts` AS `Jobadvert`
LEFT JOIN `users` AS `User` ON (`Jobadvert`.`user_id` = `User`.`id`)
LEFT JOIN `jobadverts_softwares` AS `JobadvertsSoftware_0`
ON `Jobadvert`.`id` = `JobadvertsSoftware_0.jobadvert_id`
WHERE
`Jobadvert`.`active` = 1
AND `User`.`premium` = '1'
AND Jobadvert`.`department_id` = (5)
AND JobadvertsSoftware_0`.`software_id` = '32'
AND (`JobadvertsSoftware_0`.`level` IN (1, 4) OR `JobadvertsSoftware_0`.`level` is NULL)
Assuming the level parameters in your ON clause is not needed for the join you can do a nested SELECT on your Software table to clear out the data you do not need first:
SELECT * FROM jobadverts_softwares
WHERE
(`software_id` = 32 OR `software_id` IS NULL) --Select all software_id that are 32 or null
AND
`level` IN (1, 4)
Then you can incorporate this as a nested statement in your main SQL query so you only join on the data which is filtered in your LEFT JOIN but keep any null values that you needed:
SELECT `Jobadvert`.`id`
FROM `jobadverts` AS `Jobadvert`
LEFT JOIN `users` AS `User`
ON `Jobadvert`.`user_id` = `User`.`id`
LEFT JOIN
( --Software Subquery
SELECT `jobadvert_id`, `level` FROM jobadverts_softwares
WHERE
(`software_id` = 32 OR `software_id` IS NULL) --Select all software_id that are 32 or null
AND
`level` IN (1, 4)
) AS `software_subquery`
ON `Jobadvert`.`id` = `software_subquery`.`jobadvert_id`
WHERE
`Jobadvert`.`active` = 1
AND
`User`.`premium` = '1'
AND
`Jobadvert`.`department_id` = 5
ORDER BY `Jobadvert`.`id` --Changed GROUP BY to ORDER BY as not needed
This is untested but try it out and see if this will help.
Try this:
SELECT j.id
FROM jobadverts j
LEFT JOIN User u ON (j.user_id = u.id)
LEFT JOIN jobadverts_softwares AS js ON
(j.id = js.jobadvert_id)
WHERE j.active = 1
AND u.premium = '1'
AND j.department_id = (5)
AND js.software_id` = '32'
AND js.level IN ('1', 4)))
You won't need a GROUP BY unless summing data in some way.
