Problem is application configuration that is kept in registry has a tree like structure, for example: X |->Y |->Z |->SomeKey someValue W |->AnotherKey anotherValue and so on.

• how to reuse a CASE in the WHERE ?

  - by Thibault Witzig

  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 ?

• Java: If I overwrite the .equals method, can I still test for reference equality with ==?

  - by shots fired

  I have the following situation: I need to sort trees based by height, so I made the Tree's comparable using the height attribute. However, I was also told to overwrite the equals and hashCode methods to avoid unpredictable behaviour. Still, sometimes I may want to compare the references of the roots or something along those lines using ==. Is that still possible or does the == comparison call the equals method?

• Why is i++++++++i valid in python?

  - by SysAdmin

  I "accidentally" came across this weird but valid syntax i=3 print i+++i #outputs 6 print i+++++i #outputs 6 print i+-+i #outputs 0 print i+--+i #outputs 6 (for every even no: of minus symbol, it outputs 6 else 0, why?) Does this do anything useful? Update (Don't take it the wrong way..I love python): One of Python's principle says There should be one-- and preferably only one --obvious way to do it. It seems there are infinite ways to do i+1

Or is there a workaround for SQL statement related issues in seam?

• Is objective C 2.0 a proper superset of C?

  - by RankWeis

  I've heard that objective-C is a proper superset of C, but is objective-C 2.0? The reason I ask is that either it isn't, or I misunderstand the phrase 'proper superset', because this code is valid C syntax: import int main () { char *nil = "hello"; printf("%s\n",nil); } But does not compile in Objective-C 2.0. Obviously, this is an easily fixable problem, but I'm writing a paper, and feel that this is something that should be pointed out.
