Imagine I have a mysql cursor and data read. The amount of data might be very big that I want to deal with one line each time. An easy and straight forward way might be like this: while True: row = cursor.fetchone() if not row: break ..... but this doesn't look good, so I wonder whether this way works as imagined: for row in iter(cursor.fetchall()) the thing I want to know is: if I use the iter(cursor.fetchall()) way, does it fetch all the data first or it just fetch one row at a time? Any idea is appreciated. thx The MySQLdb cursor class implements the iterator protocol , so you can simply do

I've created a ListView populated by the data returned from a query. It works, but in the LogCat I've got the message: Cursor Window: Window is full: requested allocation 444 bytes, free space 363 bytes, window size 2097152 bytes and it uses a couple of minutes for loading / visualizing the ListView. My query returns about 3700 rows of String/Int/Double, each of which with 30 columns; no images or particular datatypes What does this message exactly mean and how can I avoid it? Can you improve performances by changing this Cursor Window? Delblanco From my experience this means that the query

I'm currently in the process of making my Nintendo Wiimote (Kinda sad actually) to work with my computer as a mouse. I've managed to make the nunchuk's stick control actually move the mouse up and down, left and right on the screen! This was so exciting. Now I'm stuck. I want to left/right click on things via python when I press A, When I went to do a search, All it came up with was tkinter? So my question is, What do I call to make python left/right click on the desktop, and if it's possible, maybe provide a snippet? Thank you for your help! NOTE: I guess I forgot to mention that this is for

I have three tables. Project(Id), attribute(Id), project_attribute(Id, project_id, attribute_id) . I want to create records in project_attribute table by using all attributes from attribute table to each project from project table. To create such records i am using following store procedure. DELIMITER $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `proj_attr`() BEGIN DECLARE proj_done, attribute_done BOOLEAN DEFAULT FALSE; declare attributeId int(11) default 0; declare projectId int(11) default 0; DECLARE curProjects CURSOR FOR SELECT id FROM project order by id; DECLARE CONTINUE HANDLER FOR

I know that fetching a cursor will give me access to variables like %ROWCOUNT, %ROWTYPE, %FOUND, %NOTFOUND, %ISOPEN ...but I was wondering if there are any other reasons to use Open - Fetch - Close instructions to loop a cursor rather than Loop the cursor with a FOR cycle... (In my opinion this is better becase it is simple) What do you think? From a performance standpoint, the difference is a lot more complicated than the Tim Hall tip that OMG Ponies linked to would imply. I believe that this tip is an introduction to a larger section that has been excerpted for the web-- I expect that Tim

I've followed the instructions here and succesfully set up a UITextField that gets updated with a UIDatePicker. However the cursor in the UITextField is blinking, which seems quite a bit awkward to me. Is there any solution to get rid of that cursor? I realise this is an old question, but with the updates to iOS 7, it is now possible to hide the cursor by doing the following: [[self textFieldName] setTintColor:[UIColor clearColor]]; It will only work on iOS 7+ however.
