Query Builder, Like - doctrine-orm

Question

I have problem with Like in Query Builder:
I have SyntaxError:
[Syntax Error] line 0, col 243: Error: Expected '.' or '(', got 'type'
QueryException: SELECT z as task, GROUP_CONCAT(DISTINCT o.tahoObject) as type FROM Cloud\CrmBundle\Entity\Tasks z LEFT JOIN z.taskOwner u LEFT JOIN z.taskTasksHasObject o WHERE z.taskDone = :ztaskDone AND u.userFirstnameLastname = :uuserFirstnameLastname AND type LIKE :type GROUP BY z.taskId ORDER BY z.taskDate desc
Im adding like to the Query Builder like that:
$qb->andWhere($filter['field'][0].' LIKE :' :type);
$qb->setParameter('type', '%'.$eachOption.'%');
I checked by 'getParameters()' that type paremeter is given properly so I don't understand why I have this syntax error... Group_concat works fine too, the problem is only when i'm adding like... Any ideas ?

Answer 1

This is the query you currently have -- it is erroring because in the WHERE clause it does not know a field named type:
SELECT
z as task,
GROUP_CONCAT(DISTINCT o.tahoObject) as type
FROM Cloud\CrmBundle\Entity\Tasks z
LEFT JOIN z.taskOwner u
LEFT JOIN z.taskTasksHasObject o
WHERE z.taskDone = :ztaskDone
AND u.userFirstnameLastname = :uuserFirstnameLastname
AND type LIKE :type
GROUP BY z.taskId
ORDER BY z.taskDate desc
To fix this you need to restructure your query either this way by using GROUP_CONCAT in the where clause as well (but I am unsure if you can do the DISTINCT inside of the GROUP_CONCAT in the where clause - you can try it):
SELECT
z.taskId as task, -- z as task did not make sense to me
GROUP_CONCAT(DISTINCT o.tahoObject) as type
FROM Cloud\CrmBundle\Entity\Tasks z
LEFT JOIN z.taskOwner u -- ON ... is missing
LEFT JOIN z.taskTasksHasObject o -- ON ... is missing
WHERE z.taskDone = :ztaskDone
AND u.userFirstnameLastname = :uuserFirstnameLastname
AND GROUP_CONCAT(DISTINCT o.tahoObject) LIKE :type
GROUP BY z.taskId
ORDER BY z.taskDate desc
Or you may need to do a nested query:
SELECT task, type
FROM (
SELECT
z.taskId as task, -- z as task did not make sense to me
GROUP_CONCAT(DISTINCT o.tahoObject) as type
FROM Cloud\CrmBundle\Entity\Tasks z
LEFT JOIN z.taskOwner u -- ON ... is missing
LEFT JOIN z.taskTasksHasObject o -- ON ... is missing
WHERE z.taskDone = :ztaskDone
AND u.userFirstnameLastname = :uuserFirstnameLastname
GROUP BY z.taskId
ORDER BY z.taskDate desc
) x
WHERE x.type LIKE :type
I would also like to point out that you appear to be missing join conditions on both your LEFT JOINS. Also, selecting z as task does not make sense to me. Perhaps you meant z.taskId as task? Good luck!
