  • Generic object comparison diff routine

    - by MicMit
    The question stems from database tables comparison. Let's say we put left row in the instance Left and the right one into instance Right of the same type. And we'got many tables and respective types. How to implement more or less generic routine resulting in a collection of diffs e.g. propertyName , leftValue , rightValue for each such a pair of instances of the same type.

  • Find out which object being added to NSMutableArray is nil

    - by Raphael Caixeta
    I started a project using ARC, and I'm inserting a few objects into an NSMutableArray. The objects have all started out as NSStrings, and when attempting to add these objects into the array, I get the following error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: ' -[__NSArrayM insertObject:atIndex:]: object cannot be nil This array is holding several objects. Is there a quick way for me to find which of the objects I'm attempting to put into the array is nil?

  • Getting specific data from database

    - by ifsession
    I have a table called Categorie with a few columns and I'm trying to get only a few out of my database. So I've tried this: $sql = 'SELECT uppercat AS id, COUNT(uppercat) AS uppercat FROM categorie GROUP BY uppercat;'; $d = Yii::app()->db->createCommand($sql)->query(); But I find the output strange. I was trying to do an array_shift but I get an error that this isn't an array. When I do a var_dump on $d: object(CDbDataReader)[38] private '_statement' => object(PDOStatement)[37] public 'queryString' => string 'SELECT uppercat AS id, COUNT(uppercat) AS uppercat FROM categorie GROUP BY uppercat;' (length=100) private '_closed' => boolean false private '_row' => null private '_index' => int -1 private '_e' (CComponent) => null private '_m' (CComponent) => null Ok.. then I did a foreach on $d: array 'id' => string '0' (length=1) 'uppercat' => string '6' (length=1) array 'id' => string '3' (length=1) 'uppercat' => string '2' (length=1) array 'id' => string '6' (length=1) 'uppercat' => string '1' (length=1) array 'id' => string '7' (length=1) 'uppercat' => string '2' (length=1) array 'id' => string '9' (length=1) 'uppercat' => string '2' (length=1) Then why do I get the message that $d isn't an array while it contains arrays? Is there any other way on how to get some specific data out of my database and that I can then do an array_shift on them? I've also tried doing this with findAllBySql but then I can't reach my attribute for COUNT(uppercat) which is not in my model. I guess I'd have to add it to my model but I wouldn't like that because I need it just once.

  • Sorting an object?

    - by dfjhdfjhdf
    How to sort this object lexicographically by its keys: var obj = {'somekey_B' : 'itsvalue', 'somekey_A' : 'itsvalue'); so that it outputs like this: for (k in obj) { alert(k + ' : ' + obj[k]); //first "somekey_A : itsvalue"; then "somekey_B : itsvalue" }

  • TSQL to Map User to Database

    - by dtrick
    So I'm not able to user enterprise manager to do this... If I was I wouldn't even be asking this question. So I'm wondering if there is a way through TSQL to execute a command that maps a User to a particular Database and grants them 'owner' permissions. Thanks...

  • object reference set in java

    - by landon9720
    I need to create a Set of objects. The concern is I do not want to base the hashing or the equality on the objects' hashCode and equals implementation. Instead, I want the hash code and equality to be based only on each object's reference identity (i.e.: the value of the reference pointer). I'm not sure how to do this in Java. The reasoning behind this is my objects do not reliably implement equals or hashCode, and in this case reference identity is good enough.

  • .NET & Worflow, SqlTrackingQuery.GetWorkflows() on wire correct - presented object not

    - by UKShots
    With windows workflow when using the tracking service, the SqlTrackingQuery.GetWorkflows() method returns correctly the workflow type and assembly version on the wire from the DB query - but when one comes to query the returned SqlTrackingWorkflowInstance object it's WorkflowType.AssemblyQualifiedName property is returned as the current assembly version of the workflow type (i.e. it looks to matching on FQ type name only and not version). Anyone know how to get to the actual returned data (other than either a custom query or hook)?
