• JSON | Django passing python list

  The B-tree is of order 4, meaning that it can hold 4 pointers, and 3 keys. The following is inserted: A G I Y Since they can't all fit in one node, I know that the node will split. So I know there's going to be a root node with 2 child nodes after these things are inserted, but I don't know exactly what they'll look like.

• Which are the most noteable things which make working with Core Date so different than with MySQL?

  - by mystify

  One thing I have in mind is, that datasets in Core Data (or lets say: managed objects) have no ID like known from other databases such as MySQL. Also, they're not in a specific guaranteed order. What else makes Core Data much more "special" compared to working with a relational database like MySQL? Besides the whole object graph persisting and ORM stuff?

  Hello I'm trying to do a request that looks like this SELECT field1, field2, field3 = CASE WHEN field2 = 'something' THEN 'something' WHEN field1 IS NOT NULL and field2 IS NULL THEN 'somethingElse' ELSE NULL END FROM SomeTable WHERE field3 IS NOT NULL This results in a syntax error. I have to rewrite the CASE in the WHERE instead of just refering to it. Is there a better way to achieve this ? And out of curiosity, why is "WHERE field3 IS NOT NULL" refused while for example "ORDER BY field3" would pass ?
