  • Use a named custom column in SQL 2005 in WHERE clause?

    - by Orange Kid
    Can I name a custom column in the SELECT statement and reference that in the WHERE clause without duplicating code? For example; SELECT RIGHT(REPLICATE('0', 5) + RTRIM(SOME_ID)), 5) AS DISPLAY_ID FROM dbo.MY_TABLE WHERE DISPLAY_ID LIKE '%005%' Only much more complicated. I want to maintain this code in one place only but SQL Server 2005 forces me to duplicate the custom SELECT in the WHERE clause. I believe this was possible in Microsoft SQL Server 2000 but no longer in 2005. Thanks.

  • syntax for generating an objectForKey from an array

    - by Brian
    I'm having success when I use this code to get a string from an array called "fileList": cell.timeBeganLabel.text = [[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]; so I expected the same code to generate the same string as a key for me in this: NSDictionary *stats = [thisRecordingsStats objectForKey:[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; cell.durationLabel.text = [stats objectForKey:@"duration"]; or this: NSDictionary *stats = [thisRecordingsStats objectForKey:@"%@",[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; Both build without error, and the log shows my data is there: but I'm getting a blank UILabel. Have I not written the dynamic key generator correctly?

  • NoneType has no attribute Append

    - by Rosarch
    I'm new to Python. I can't understand why a variable is None at a certain point in my code: class UsersInRoom(webapp.RequestHandler): def get(self): room_id = self.request.get("room_id") username = self.request.get("username") UserInRoom_entities = UserInRoom.gql("WHERE room = :1", room_id).get() if UserInRoom_entities: for user_in_room in UserInRoom_entities: if user_in_room.username == username: user_in_room.put() # last_poll auto updates to now whenenever user_in_room is saved else: user_in_room = UserInRoom() user_in_room.username = username user_in_room.put() UserInRoom_entities = [] UserInRoom_entities.append(user_in_room) // error here # name is `user_at_room` intead of `user_in_room` to avoid confusion usernames = [user_at_room.username for user_at_room in UserInRoom_entities] self.response.out.write(json.dumps(usernames)) The error is: Traceback (most recent call last): File "C:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 507, in __call__ handler.get(*groups) File "path\to\chat.py", line 160, in get AttributeError: 'NoneType' object has no attribute 'append' How is this possible? I'm setting UserInRoom_entities = [] immediately before that call. Or is something else the None in question?

  • Effect of suffixes in memory operations

    - by tur1ng
    In x86 GNU Assembler there are different suffixes for memory related operations. E.g.: movb, movs, movw, movl, movq, movt(?) Now my question is the following: Does the suffix has ANY effect on how the processor is getting the data out of main memory or will always be one or more 32-bit (x86) chunks loaded into the cache ? What are the effects beside the memory access?

  • C++: Trouble with tr1::bind (C2065)

    - by Rosarch
    I'm getting a compiler error with bind: using namespace std; bool odp(int arg1, int arg2); // ... find_if(vec.begin(), vec.end(), tr1::bind(odp, iValue, _1)); // C2065 My goal is to curry odp(), so its first argument is iValue, and apply that function in find_if. The error: C2065: '_1' : undeclared identifier. What am I doing wrong?

  • PHP while(variable=mysql_fetch_assoc) - explanation

    - by Petr
    Hi, I have been working with C# so this is quite strange for me: while($variable=mysql_fetch_assoc) I have not been able to look up in PHP manual how it works. I guess that in each loop it advances to next element of assoc.array. But what is this generally called in PHP? I am just not used to see '=' in loop condition.

  • which sql consumes less memory

    - by prmatta
    Yesterday I asked a question on how to re-write sql to do selects and inserts in batches. I needed to do this to try and consume less virtual memory, since I need to move millions of rows here. The object is to move rows from Table B into Table A. Here are the ways I can think of doing this: SQL #1) INSERT INTO A (x, y, z) SELECT x, y, z FROM B b WHERE ... SQL #2) FOREACH SELECT x,y,z FROM B b WHERE ... INSERT INTO A(x,y,z); END FOREACH; SQL #3) FOREACH SELECT FIRST 2000 x,y,z FROM B b WHERE ... INSERT INTO A(x,y,z); END FOREACH; SQL #4) FOREACH SELECT FIRST 2000 x,y,z FROM B b WHERE ... AND NOT EXISTS IN (SELECT * FROM A) INSERT INTO A(x,y,z); END FOREACH; Are any of the above incorrect? The database is informix 11.5.

  • JSON Syntax, what is this?

    - by danp
    I understand concepts of JSON ok, but after starting to use ebay's api, I came across a notation which I've not seen before, and was wondering if anyone could explain what's going on with it? { "findItemsByKeywordsResponse": [ { "ack": [ "Success" ], "version": [ "1.5.0" ], "timestamp": [ "2010-06-16T08:42:21.468Z" ], "searchResult": [ { "@count": "0" } ], "paginationOutput": [ { "pageNumber": [ "0" ], "entriesPerPage": [ "10" ], "totalPages": [ "0" ], "totalEntries": [ "0" ] } ] } ] } What's the "@count" thing? I noticed when I reference it in chrome, it throws an error: But in Firefox not. JSON Lint reports it's valid, as I'd expect... ;)

  • Include code file into C#? Create library for others?

    - by Tomas
    Hi, I would like to know how can I embedd a code source file (if possible), something like that: class X { include "ClassXsource" } My second question - Can I build DLL or something like that for my colleagues to use? I need them to be able to call methods from my "part" but do not modify or view their content. Basically just use namespace "MyNamespace" and call its methods, but I have never done anything like that. Thanks

  • Programming terms - field, member, properties (C#)

    - by Petr
    Hi, I was trying to find meaning of this terms but especially due to language barrier I was not able to understand what they are used for. I assume that "field" is variable (object too?) in the class while "property" is just an object that returns specific value and cannot contain methods etc. By "member" I understand any object that is declared on the class level. But these are just my assumptions based on commented code samples where some careful programmers used "property region" etc. I would really appreciate if someone could explain it to me.
