I have written a MySQL query ?I want to fetch data t.taskid = b.id OR t.taskid = '0' AND t.subtaskid = j.id OR t.subtaskid = '0' from this but where condition is not working for this
SELECT t.id as id
, t.taskid
, t.subtaskid
, p.PNAME AS projectname
, t.date AS DATE
, b.Summary AS tasks
, j.SUMMARY AS subtasks
, t.mon AS time1
, t.tue AS time2
, t.wed AS time3
, t.thu AS time4
, t.fri AS time5
, t.sat AS time6
, t.sun AS time7
FROM bt_createissue b
, bt_createissue j
, timesheet t
LEFT
JOIN bt_project p
ON t.projectid = p.pkey
WHERE t.taskid = b.id
OR t.taskid = 0
AND t.subtaskid = j.id
OR t.subtaskid = 0
AND t.date >= '2015-03-09'
AND t.date <= '2015-03-30'
AND t.username = '$username'
If t.taskid = b.id
t.subtaskid = j.id are to be joins then check whether you can modify
WHERE t.taskid = b.id OR t.taskid = '0'
AND t.subtaskid = j.id OR t.subtaskid = '0'
the above lines with proper joins.
Because using join conditions in where clause can create cross join instead of intended one.
If it do not work
Try with using having clause instead of where clause and don't forget to use group by

I am trying to join 3 tables with UNION ALL. I tried the following code. and giving this error of Invalid parameter number: number of bound variables does not match number of tokens.
$codeArray = explode(',', $code);
$inQuery = implode(',', array_fill(0, count($codeArray), '?'));
$full_dt = date('Y-m-d H:i:s');
$query = "SELECT * FROM
(
SELECT
a.*
FROM pat_info a
INNER JOIN
pat_medication b
ON a.id = b.pat_id
WHERE
a.status != 2 AND b.status != 2
AND '$full_dt' BETWEEN b.start_date AND b.end_date
AND a.location_code IN ($inQuery)
AND b.stock_status != '2'
AND (b.total_qty - (b.given + b.not_taken)) < 12
UNION ALL
SELECT
a.*
FROM pat_info a
INNER JOIN
prn_medication b
ON a.id = b.pat_id
WHERE
a.status != 2 AND b.status != 2
AND '$full_dt' BETWEEN b.start_date AND b.end_date
AND a.location_code IN ($inQuery)
AND b.stock_status != '2'
AND (b.total_qty - (b.given + b.not_taken)) < 12
) x
GROUP BY a.id ORDER BY a.id DESC";
$statement = $con->prepare($query);
$statement->execute($codeArray);
As you have the in clause twice in your code, you need to bind the values twice.
A simple way to do this would be to duplicate the data prior to the execute()...
$codeArray = array_merge($codeArray, $codeArray);
You also need to change
GROUP BY a.id ORDER BY a.id DESC
to
GROUP BY x.id ORDER BY x.id DESC
as the a alias is in the sub-select and not the overall SELECT.
I have a query that is using a subquery, and I can't seem to figure out why it is telling me I have duplicate methodID's. The query is supposed to take the data and order by and group by for showing only the latest single result for a given studentID where there could be multiple results with different timestamps but same studentID
SELECT a.*
FROM
( SELECT *
, o.methodName oldName
, n.methodName newName
, s.firstName fName
, s.lastName lName
FROM changeReport r
LEFT
JOIN methodLookup o
ON o.methodID = r.oldMethod
LEFT
JOIN methodLookup n
ON n.methodID = r.newMethod
JOIN students s
ON s.studentID = r.studentID
LEFT
JOIN staffaccounts a
ON r.staffID = a.staffID
WHERE 31 IN (newSubMethod,oldSubMethod)
AND date(timestamp) = CURRENT_DATE
) a
JOIN
( SELECT students.studentID
, MAX(timestamp) timestamp
FROM changeReport r
LEFT
JOIN methodLookup o
ON o.methodID = r.oldMethod
LEFT
JOIN methodLookup n
ON n.methodID = r.newMethod
JOIN students s
ON s.studentID = r.studentID
LEFT
JOIN staffaccounts a
ON r.staffID = a.staffID
WHERE 31 IN (newSubMethod,oldSubMethod)
AND date(timestamp) = CURRENT_DATE
) b
ON b.studentID = a.studentID
AND b.timestamp = a.timestamp;
Any ideas on how this could be?
I am using this mysql query
SELECT `p`.`id` AS product_id, `p`.`title` , `i`.`image` , `u`.`user_username` , `m`.`id` AS message_id, `m`.`date` , `m`.`from` , `m`.`to` , `m`.`message` , `m`.`read`
FROM (`messages` AS m)
JOIN `products` AS p ON `m`.`product_id` = `p`.`id`
JOIN `users` AS u ON `m`.`from` = `u`.`user_id`
JOIN `product_images` AS i ON `p`.`id` = `i`.`product_id`
WHERE `i`.`type` = 'FRONT'
AND (m.to = '1171' OR m.from = '1171)
GROUP BY `m`.`therad_user` , `m`.`product_id`
ORDER BY `m`.`id` DESC
In message table it shows message with oldest message id, I want to return latest message. but it show oldest message. how I solve this.
Try ORDER BY first, then only GROUP BY
SELECT * FROM
(
SELECT `p`.`id` AS product_id, `p`.`title` , `i`.`image` , `u`.`user_username` , `m`.`id` AS message_id, `m`.`date` , `m`.`from` , `m`.`to` , `m`.`message` , `m`.`read`
FROM (`messages` AS m)
JOIN `products` AS p ON `m`.`product_id` = `p`.`id`
JOIN `users` AS u ON `m`.`from` = `u`.`user_id`
JOIN `product_images` AS i ON `p`.`id` = `i`.`product_id`
WHERE `i`.`type` = 'FRONT'
AND (m.to = '1171' OR m.from = '1171)
ORDER BY `m`.`id` DESC
) tmp
GROUP BY `m`.`therad_user` , `m`.`product_id`
i have the following query which gives desired output in mysql , now i want to implement it in zend query language,
which has different approach to implement the query..
SELECT A.NAME , B.PAYMENT , C.TOTALPROJ , D.TOTALTASK , T.ACTIVETASK , H.HOUR
FROM USERMASTER AS A
LEFT OUTER JOIN
(
SELECT A.U_ID , SUM(A.TOTALTIME * B.RATE) AS PAYMENT
FROM
(
SELECT U_ID , PROJECT_ID ,
SUM(TIME_TO_SEC(CASE WHEN endtime is null then timediff (starttime,starttime)
ELSE timediff (endtime,starttime) END )) / 3600 AS TOTALTIME
FROM LOGMASTER AS A
WHERE PROJECT_ID IS NOT NULL
GROUP BY U_ID , PROJECT_ID
) AS A
INNER JOIN PROJECTTOUSER AS B ON A.PROJECT_ID = B.PROJECT_ID AND A.U_ID = B.U_ID
GROUP BY B.U_ID
) AS B ON A.ID = B.U_ID
LEFT OUTER JOIN
(
SELECT U_ID , COUNT(*) AS TOTALPROJ FROM PROJECTTOUSER GROUP BY U_ID
) AS C ON A.ID = C.U_ID
LEFT OUTER JOIN
(
SELECT ASSIGNED_TO , COUNT(*) AS TOTALTASK FROM TASKTOTARGET GROUP BY ASSIGNED_TO
) AS D ON A.ID = D.ASSIGNED_TO
LEFT OUTER JOIN
(
SELECT ASSIGNED_TO,COUNT(*) AS ACTIVETASK FROM TASKTOTARGET WHERE
IS_ACTIVE = 0 GROUP BY ASSIGNED_TO
) AS T ON A.ID = T.ASSIGNED_TO
LEFT OUTER JOIN
(
SELECT U_ID, SEC_TO_TIME(SUM(TIME_TO_SEC(CASE WHEN endtime is null then
timediff (starttime,starttime) ELSE timediff (endtime,starttime) END ))) AS HOUR
FROM LOGMASTER WHERE INSERT_DATE >= '2013-08-20' AND INSERT_DATE <='2013-08-31'
GROUP BY U_ID
) AS H ON A.ID = H.U_ID
so if any one can guide me in how to create this query in zend then it will be very helpful, and appreciated
Each of your subqueries becomes an new Zend_Query that you can then use just like a table and pass in to the main query.
For example:
$h = new Zend_Db_Select()
->from('LOGMASTER', array('U_ID', 'HOUR' => new Zend_Db_Expr('SEC_TO_TIME(SUM(TIME_TO_SEC(CASE WHEN endtime is null then
timediff (starttime,starttime) ELSE timediff (endtime,starttime) END ))))')
->where("INSERT_DATE >= '2013-08-20'")
->where("INSERT_DATE <= '2013-08-31'")
->group('U_ID');
$mainQuery = new Zend_Db_Select()
->from('a' => 'USERMASTER', array('NAME'))
->joinLeft($h, 'A.ID = H.U_IS', array('HOUR'));
You would create each of your subqueries as its own object and then you can join them into your main query. The last argument of the join function is which columns from the subquery should be added to the main query.
With ZF's fluid interface you can keep joining tables/queries until you have built your entire query.

With this query i will find all apartments that are available.
All the available apartments have no booking id.
What i want: When it has a booking id and the status is cancelled I also want the apartment to show up, but i don't know how to…
SELECT a.id, a.num_persons, a.rating, a.lat, a.lng, a.street, a.number
,c.title, c.introduction, c.text, c.area, c.long_term_rental, c.beds
, c.features ,c.services_and_equipment, c.terms_and_conditions
, m.url
FROM appartments AS a
INNER JOIN appartments_content AS c on c.parent_id = a.id
INNER JOIN meta AS m on m.id = c.meta_id
LEFT JOIN appartments_bookings AS b
ON (b.appartment_id = a.id
AND NOT ((? > b.departure) OR (? < b.arrival)))
-- this ? = arrival that ? = departure
WHERE b.id IS NULL
AND c.language = ?
AND a.hidden = ?
AND a.publish_on <= ?
AND a.city_id = ?
AND a.num_persons >= ?
ORDER BY a.num_persons ASC, a.publish_on DESC
LIMIT ? OFFSET ?'
I added this:
AND b.status != ? OR NOT ((? >= b.departure) OR (? < b.arrival))) WHERE b.order_id IS NULL
But this doesn't work, i get nog results.
Don't know mySQL syntax but change your WHERE to clause to something like...
WHERE (b.id IS NULL OR (b.id IS NOT NULL AND b.status = 'cancelled'))
AND c.language = etc etc
