• Problem getting weeks in a month...

  - by AngrySpade

  I am creating a calendar control of sorts... One thing I need to know is how many weeks are there in a Month... So NSCalendar rangeOfUnit:inUnit:forDate Seems to be exactly what I need... Except I am noticing something that seems off and I can't quite figure out why this is happening... The following code... NSCalendar *calendar = [NSCalendar currentCalendar]; NSDateComponents *dateComponents = [[NSDateComponents alloc] init]; [dateComponents setYear: 2010]; [dateComponents setDay: 1]; for (int x=1; x<=12; x++) { [dateComponents setMonth: x]; NSDate *date = [calendar dateFromComponents:dateComponents]; NSLog(@"Date: %@", date); NSRange range = [calendar rangeOfUnit: NSWeekCalendarUnit inUnit: NSMonthCalendarUnit forDate:date]; NSLog(@"%d Weeks in Month %d", range.length, [dateComponents month]); } Is returning the following debug messages... 2010-03-14 13:08:10.350 Scrap[4256:207] Date: 2010-01-01 00:00:00 -0500 2010-03-14 13:08:10.351 Scrap[4256:207] 5 Weeks in Month 1 2010-03-14 13:08:10.352 Scrap[4256:207] Date: 2010-02-01 00:00:00 -0500 2010-03-14 13:08:10.352 Scrap[4256:207] 4 Weeks in Month 2 2010-03-14 13:08:10.353 Scrap[4256:207] Date: 2010-03-01 00:00:00 -0500 2010-03-14 13:08:10.353 Scrap[4256:207] 5 Weeks in Month 3 2010-03-14 13:08:10.354 Scrap[4256:207] Date: 2010-04-01 00:00:00 -0400 2010-03-14 13:08:10.355 Scrap[4256:207] 5 Weeks in Month 4 2010-03-14 13:08:10.356 Scrap[4256:207] Date: 2010-05-01 00:00:00 -0400 2010-03-14 13:08:10.357 Scrap[4256:207] 5 Weeks in Month 5 2010-03-14 13:08:10.358 Scrap[4256:207] Date: 2010-06-01 00:00:00 -0400 2010-03-14 13:08:10.358 Scrap[4256:207] 5 Weeks in Month 6 2010-03-14 13:08:10.359 Scrap[4256:207] Date: 2010-07-01 00:00:00 -0400 2010-03-14 13:08:10.360 Scrap[4256:207] 5 Weeks in Month 7 2010-03-14 13:08:10.361 Scrap[4256:207] Date: 2010-08-01 00:00:00 -0400 2010-03-14 13:08:10.364 Scrap[4256:207] 5 Weeks in Month 8 2010-03-14 13:08:10.364 Scrap[4256:207] Date: 2010-09-01 00:00:00 -0400 2010-03-14 13:08:10.365 Scrap[4256:207] 5 Weeks in Month 9 2010-03-14 13:08:10.366 Scrap[4256:207] Date: 2010-10-01 00:00:00 -0400 2010-03-14 13:08:10.366 Scrap[4256:207] 5 Weeks in Month 10 2010-03-14 13:08:10.367 Scrap[4256:207] Date: 2010-11-01 00:00:00 -0400 2010-03-14 13:08:10.367 Scrap[4256:207] 5 Weeks in Month 11 2010-03-14 13:08:10.369 Scrap[4256:207] Date: 2010-12-01 00:00:00 -0500 2010-03-14 13:08:10.369 Scrap[4256:207] 52 Weeks in Month 12 I cant quite figure out why I get 52 weeks in month 12. Any clues? Edit on 3/20/2010: Seeing as how I couldnt use rangeOfUnit:inUnit:forDate to calculate the number of weeks in a month. I decided to figure out a different way of calculating the same value. I figured I should do this in a non-Gregorian localized way, so I attempted to start with getting the number of days in a week, but I got the result of 28 days in a week. So I started writing more code to figure out why... I wanted to make sure that the type of NSCalendar that I was playing with was in fact what I was supposed to be getting... And that led me to finding some differences... NSCalendar *currentCalendar = [NSCalendar currentCalendar]; NSLog(@"Calendar with 'currentCalendar' Identifier: %@", [currentCalendar calendarIdentifier]); NSCalendar *calendarWithIdentifier = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar] autorelease]; NSLog(@"Calendar created with identifier Identifier: %@", [calendarWithIdentifier calendarIdentifier]); NSDate *now = [[NSDate alloc] init]; NSDateComponents *currentMonth = [currentCalendar components: NSMonthCalendarUnit | NSYearCalendarUnit fromDate: now]; NSDate *currentMonthDate = [currentCalendar dateFromComponents: currentMonth]; NSRange daysInWeekRange = [currentCalendar rangeOfUnit: NSDayCalendarUnit inUnit: NSWeekCalendarUnit forDate: currentMonthDate]; NSLog(@"CurrentCalendar: Length:%u Location:%u", daysInWeekRange.length, daysInWeekRange.location); currentMonth = [calendarWithIdentifier components: NSMonthCalendarUnit | NSYearCalendarUnit fromDate: now]; currentMonthDate = [calendarWithIdentifier dateFromComponents: currentMonth]; daysInWeekRange = [calendarWithIdentifier rangeOfUnit: NSDayCalendarUnit inUnit: NSWeekCalendarUnit forDate: currentMonthDate]; NSLog(@"GregorianCalendar: Length:%u Location:%u", daysInWeekRange.length, daysInWeekRange.location); And that got me the following log results... 2010-03-20 21:02:27.245 Scrap[52189:207] Calendar with 'currentCalendar' Identifier: gregorian 2010-03-20 21:02:27.246 Scrap[52189:207] Calendar created with identifier Identifier: gregorian 2010-03-20 21:02:27.248 Scrap[52189:207] CurrentCalendar: Length:28 Location:1 2010-03-20 21:02:27.249 Scrap[52189:207] GregorianCalendar: Length:7 Location:1 Taking direction from @CarlNorum's experience, I compiled the code snippet as a 10.6 Cocoa application, and I got the following... 2010-03-20 21:05:35.636 ScrapCocoa[52238:a0f] Calendar with 'currentCalendar' Identifier: gregorian 2010-03-20 21:05:35.636 ScrapCocoa[52238:a0f] Calendar created with identifier Identifier: gregorian 2010-03-20 21:05:35.637 ScrapCocoa[52238:a0f] CurrentCalendar: Length:6 Location:1 2010-03-20 21:05:35.638 ScrapCocoa[52238:a0f] GregorianCalendar: Length:7 Location:1 I saw hope in that creating a NSCalendar Instance explicitly as a Gregorian Calendar would lead to better results in my original problem... So I modified that original code NSCalendar *currentCalendar = [NSCalendar currentCalendar]; NSLog(@"Calendar with 'currentCalendar' Identifier: %@", [currentCalendar calendarIdentifier]); NSCalendar *calendarWithIdentifier = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar] autorelease]; NSLog(@"Calendar created with identifier Identifier: %@", [calendarWithIdentifier calendarIdentifier]); NSDateComponents *dateComponents = [[[NSDateComponents alloc] init] autorelease]; [dateComponents setYear: 2010]; [dateComponents setDay: 1]; for (int x=1; x<=12; x++) { [dateComponents setMonth: x]; NSDate *date = [currentCalendar dateFromComponents: dateComponents]; NSRange range = [currentCalendar rangeOfUnit: NSWeekCalendarUnit inUnit: NSMonthCalendarUnit forDate: date];

And the situation is I am loading the ListView properly.But while loading ListView I am disabling some button in the ListView by checking one parameter. Up to this point ListView is showing it's row properly. But when I am scrolling the ListView at that time previously enabled Button are getting disabled.What I am doing wrong I am not getting can one please point out my mistake Or any suggestion. Here is my Adapter class. public class OrderSmartKitchenAdapter extends BaseAdapter { private int flagDeliveryComplete = 0; private int flagPreparationComplete = 0; private int flagPreparationStarted = 0;

• Issue in setting alarm time in AlarmManager Class

  - by Anshuman

  I have used the following code in setting alarm time in AlarmManager class. Now Suppose my device current date 9-july-2012 11:31:00, Now suppose i set set a alarm at 9-july-2012 11:45:00, then it works fine and pop-up an alarm at that time. But if i set an alarm at 10-aug-2012 11:40:00, then as soon as exit the app the alarm pop-up, which is wrong because i set an alarm at month of august, So why this happen, is anything wrong in my code. if anyone knows help me to solve this out. Code For Setting Alarm time in AlarmManager class Intent myIntent = new Intent(context, AlarmService.class); PendingIntent pendingIntent = PendingIntent.getService(context, i, myIntent, i); AlarmManager alarmManager = (AlarmManager)context.getSystemService(AlarmService.ALARM_SERVICE); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.add(Calendar.MILLISECOND, (int) dateDifferenceFromSystemTime(NoteManager.getSingletonObject().getAlarmTime(i))); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent); public static long dateDifferenceFromSystemTime(Date date) { long difference = 0; try { Calendar c = Calendar.getInstance(); difference = date.getTime() - c.getTimeInMillis(); if (difference < 0) { // if difference is -1 - means alarm time is of previous time then current // then firstly change it to +positive and subtract form 86400000 to get exact new time to play alarm // 86400000-Total no of milliseconds of 24hr Day difference = difference * -1; difference = 86400000 - difference; } } catch (Exception e) { e.printStackTrace(); } return difference; } Service class which pop-up alarm when matches time public class AlarmService extends IntentService { public void onCreate() { super.onCreate(); } public AlarmService() { super("MyAlarmService"); } @Override public int onStartCommand(Intent intent, int flags, int startId) { super.onStartCommand(intent, startId, startId); return START_STICKY; } @Override protected void onHandleIntent(Intent intent) { startActivity(new Intent(this,AlarmDialogActivity.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)); } }

• Need to include Calendar and Email in own CRM system. Whose?

  - by PurplePilot

  I am writing a web based application that needs to have some elements of CRM in it but I cannot use an of-the-shelf CRM to do what I want. (Honestly we have been through it all and it will not work). Now while Tasks, Calls, Meetings and Notes are straightforward the idea of reinventing Mail and Calendars seems a waste of time and effort and also unproductive as most users already have their own and it simply adds to the complexity of my application and hacks users off. My thoughts are going around using Outlook and or GMail/iCal and or Mac Mail/iCal and or Thunderbird and importing the relevant data or if possible integrating it into the application. Any thoughts? Anyone got any experience of this can point me in a few directions. N.B. Not looking for an answer as too complex just some pointers and thoughts. Thanks. p.s. We did look at Sugar CRM as the basis for our project and it is useful to get best practice from but as I say it was not useable due to how we are structuring our software, not Sugar's fault.

• fullCalendar not rendering new events dynamically

  - by morpheous

  I have the following code in a page on which I am using fullCalendar. I am able to add events in my page, however the calendar does not display this dynamically. I have to move to another month (and then back to the current month), before the dates I added are displayed. Is there a way to dynamically refresh/render the calendar as dates are programatically added to it? Here is a snippet of my code so far: ## the code for generating the calendar <script> $(document).ready(function() { $('#calendar').fullCalendar({ editable: false, events: 'http://example.com/getevents.php', }); }); </script> <h1>Calendar Test</h1> <div id='calendar'></div> ## the code for updating it $('#calendar').fullCalendar( 'refetchEvents' );

• Android repeating alarm not working

  - by erdomester

  This works fine: Intent intent = new Intent(HelloAndroid2.this, AlarmReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(HelloAndroid2.this, 0, intent, PendingIntent.FLAG_ONE_SHOT); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (12 * 1000), pendingIntent); This doesn't work. I hear the alarm only time. alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (12 * 1000), 3 * 1000, pendingIntent); I have also tried this, no luck: Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.add(Calendar.SECOND, 5); alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 7000, pendingIntent); What is the problem?

• android alarm not able to launch alarm activity

  - by user965830

  I am new to android programming and am trying to make this simple alarm app. I have my code written and it is compiled with no errors. The app runs in the emulator, that is the main activity asks the date and time, but when i click on the confirm button, it displays the message - "Unfortunately, Timer1 has stopped working." The code for my main activity is as follows: public void onClick(View v) { EditText date = (EditText) findViewById(R.id.editDate); EditText month = (EditText) findViewById(R.id.editMonth); EditText hour = (EditText) findViewById(R.id.editHour); EditText min = (EditText) findViewById(R.id.editMin); int dt = Integer.parseInt(date.getText().toString()); int mon = Integer.parseInt(month.getText().toString()); int hr = Integer.parseInt(hour.getText().toString()); int mnt = Integer.parseInt(min.getText().toString()); Intent myIntent = new Intent(MainActivity.this, AlarmActivity.class); pendingIntent = PendingIntent.getService(MainActivity.this, 0, myIntent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); Calendar calendar = Calendar.getInstance(); calendar.set(Calendar.DATE, dt); calendar.set(Calendar.MONTH, mon); calendar.set(Calendar.HOUR, hr); calendar.set(Calendar.MINUTE, mnt); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent); } I do not understand what all the errors in logcat mean, so i am posting them: 06-25 16:03:32.175: I/Process(566): Sending signal.

• Trouble with datasource not being called from viewWillAppear

  - by user278859

  A little background. I have taken GCCalendar which only works in portrait orientation and extended it to work in landscape similar to how the iPhone's Calendar app works. I did this by duplicating the main view class and modifying it to work in landscape. So when the phone is in portrait orientation the CGCalendar is instantiated from the apps main view controller using the original portrait view class and when in landscape orientation using the new modified landscape view class. Most of the other classes in GCCalendar are shared without modification. A few had to be duplicated as well. I got it all working great except for an issue with the datasource. The datasource is called when the calendar is first loaded and each time the user changes the dates being viewed. Problem is I can't get the datasource call to work on the first call. I am stumped as it works fine in portrait orientation and I cannot find any difference between the 2 versions. Following is some of the code that shows how it gets to the datasource call the first time. Subsequent calls removes all the calendar subviews and instantiates them again with the new dates. The duplicated landscape class names end in LS. Otherwise as you can see they are identical. Does anyone has any idea of where else I might look to resolve this issue? Thanks, John -------------------------------- //App main view controller - (void)showLandscapeCalendar { GCCalendarLandscapeView *calendar = [[[GCCalendarLandscapeView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (void)showPortraitCalendar { GCCalendarPortraitView *calendar = [[[GCCalendarPortraitView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (NSArray *)calendarEventsForDate:(NSDate *)date{ //build and return the events array //this is the protocol datasource method //It is supposed to run every time the date changes in the calendar } ------------------------------- // GCCalendarLandscapeView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayViewLS *nextDayView = [[GCCalendarDayViewLS alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayViewLS - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { //** first time through the dataSource method does not run events = [dataSource calendarEventsForDate:date]; } ------------------------------- // GCCalendarPortraitView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayView *nextDayView = [[GCCalendarDayView alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayView - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { **//this one works every time events = [dataSource calendarEventsForDate:date]; }

• Hello Operator, My Switch Is Bored

  - by Paul White

  This is a post for T-SQL Tuesday #43 hosted by my good friend Rob Farley. The topic this month is Plan Operators. I haven’t taken part in T-SQL Tuesday before, but I do like to write about execution plans, so this seemed like a good time to start. This post is in two parts. The first part is primarily an excuse to use a pretty bad play on words in the title of this blog post (if you’re too young to know what a telephone operator or a switchboard is, I hate you). The second part of the post looks at an invisible query plan operator (so to speak). 1. My Switch Is Bored Allow me to present the rare and interesting execution plan operator, Switch: Books Online has this to say about Switch: Following that description, I had a go at producing a Fast Forward Cursor plan that used the TOP operator, but had no luck. That may be due to my lack of skill with cursors, I’m not too sure. The only application of Switch in SQL Server 2012 that I am familiar with requires a local partitioned view: CREATE TABLE dbo.T1 (c1 int NOT NULL CHECK (c1 BETWEEN 00 AND 24)); CREATE TABLE dbo.T2 (c1 int NOT NULL CHECK (c1 BETWEEN 25 AND 49)); CREATE TABLE dbo.T3 (c1 int NOT NULL CHECK (c1 BETWEEN 50 AND 74)); CREATE TABLE dbo.T4 (c1 int NOT NULL CHECK (c1 BETWEEN 75 AND 99)); GO CREATE VIEW V1 AS SELECT c1 FROM dbo.T1 UNION ALL SELECT c1 FROM dbo.T2 UNION ALL SELECT c1 FROM dbo.T3 UNION ALL SELECT c1 FROM dbo.T4; Not only that, but it needs an updatable local partitioned view. We’ll need some primary keys to meet that requirement: ALTER TABLE dbo.T1 ADD CONSTRAINT PK_T1 PRIMARY KEY (c1);   ALTER TABLE dbo.T2 ADD CONSTRAINT PK_T2 PRIMARY KEY (c1);   ALTER TABLE dbo.T3 ADD CONSTRAINT PK_T3 PRIMARY KEY (c1);   ALTER TABLE dbo.T4 ADD CONSTRAINT PK_T4 PRIMARY KEY (c1); We also need an INSERT statement that references the view. Even more specifically, to see a Switch operator, we need to perform a single-row insert (multi-row inserts use a different plan shape): INSERT dbo.V1 (c1) VALUES (1); And now…the execution plan: The Constant Scan manufactures a single row with no columns. The Compute Scalar works out which partition of the view the new value should go in. The Assert checks that the computed partition number is not null (if it is, an error is returned). The Nested Loops Join executes exactly once, with the partition id as an outer reference (correlated parameter). The Switch operator checks the value of the parameter and executes the corresponding input only. If the partition id is 0, the uppermost Clustered Index Insert is executed, adding a row to table T1. If the partition id is 1, the next lower Clustered Index Insert is executed, adding a row to table T2…and so on. In case you were wondering, here’s a query and execution plan for a multi-row insert to the view: INSERT dbo.V1 (c1) VALUES (1), (2); Yuck! An Eager Table Spool and four Filters! I prefer the Switch plan. My guess is that almost all the old strategies that used a Switch operator have been replaced over time, using things like a regular Concatenation Union All combined with Start-Up Filters on its inputs. Other new (relative to the Switch operator) features like table partitioning have specific execution plan support that doesn’t need the Switch operator either. This feels like a bit of a shame, but perhaps it is just nostalgia on my part, it’s hard to know. Please do let me know if you encounter a query that can still use the Switch operator in 2012 – it must be very bored if this is the only possible modern usage! 2. Invisible Plan Operators The second part of this post uses an example based on a question Dave Ballantyne asked using the SQL Sentry Plan Explorer plan upload facility. If you haven’t tried that yet, make sure you’re on the latest version of the (free) Plan Explorer software, and then click the Post to SQLPerformance.com button. That will create a site question with the query plan attached (which can be anonymized if the plan contains sensitive information). Aaron Bertrand and I keep a close eye on questions there, so if you have ever wanted to ask a query plan question of either of us, that’s a good way to do it. The problem The issue I want to talk about revolves around a query issued against a calendar table. The script below creates a simplified version and adds 100 years of per-day information to it: USE tempdb; GO CREATE TABLE dbo.Calendar ( dt date NOT NULL, isWeekday bit NOT NULL, theYear smallint NOT NULL,   CONSTRAINT PK__dbo_Calendar_dt PRIMARY KEY CLUSTERED (dt) ); GO -- Monday is the first day of the week for me SET DATEFIRST 1;   -- Add 100 years of data INSERT dbo.Calendar WITH (TABLOCKX) (dt, isWeekday, theYear) SELECT CA.dt, isWeekday = CASE WHEN DATEPART(WEEKDAY, CA.dt) IN (6, 7) THEN 0 ELSE 1 END, theYear = YEAR(CA.dt) FROM Sandpit.dbo.Numbers AS N CROSS APPLY ( VALUES (DATEADD(DAY, N.n - 1, CONVERT(date, '01 Jan 2000', 113))) ) AS CA (dt) WHERE N.n BETWEEN 1 AND 36525; The following query counts the number of weekend days in 2013: SELECT Days = COUNT_BIG(*) FROM dbo.Calendar AS C WHERE theYear = 2013 AND isWeekday = 0; It returns the correct result (104) using the following execution plan: The query optimizer has managed to estimate the number of rows returned from the table exactly, based purely on the default statistics created separately on the two columns referenced in the query’s WHERE clause. (Well, almost exactly, the unrounded estimate is 104.289 rows.) There is already an invisible operator in this query plan – a Filter operator used to apply the WHERE clause predicates. We can see it by re-running the query with the enormously useful (but undocumented) trace flag 9130 enabled: Now we can see the full picture. The whole table is scanned, returning all 36,525 rows, before the Filter narrows that down to just the 104 we want. Without the trace flag, the Filter is incorporated in the Clustered Index Scan as a residual predicate. It is a little bit more efficient than using a separate operator, but residual predicates are still something you will want to avoid where possible. The estimates are still spot on though: Anyway, looking to improve the performance of this query, Dave added the following filtered index to the Calendar table: CREATE NONCLUSTERED INDEX Weekends ON dbo.Calendar(theYear) WHERE isWeekday = 0; The original query now produces a much more efficient plan: Unfortunately, the estimated number of rows produced by the seek is now wrong (365 instead of 104): What’s going on? The estimate was spot on before we added the index! Explanation You might want to grab a coffee for this bit. Using another trace flag or two (8606 and 8612) we can see that the cardinality estimates were exactly right initially: The highlighted information shows the initial cardinality estimates for the base table (36,525 rows), the result of applying the two relational selects in our WHERE clause (104 rows), and after performing the COUNT_BIG(*) group by aggregate (1 row). All of these are correct, but that was before cost-based optimization got involved :) Cost-based optimization When cost-based optimization starts up, the logical tree above is copied into a structure (the ‘memo’) that has one group per logical operation (roughly speaking). The logical read of the base table (LogOp_Get) ends up in group 7; the two predicates (LogOp_Select) end up in group 8 (with the details of the selections in subgroups 0-6). These two groups still have the correct cardinalities as trace flag 8608 output (initial memo contents) shows: During cost-based optimization, a rule called SelToIdxStrategy runs on group 8. It’s job is to match logical selections to indexable expressions (SARGs). It successfully matches the selections (theYear = 2013, is Weekday = 0) to the filtered index, and writes a new alternative into the memo structure. The new alternative is entered into group 8 as option 1 (option 0 was the original LogOp_Select): The new alternative is to do nothing (PhyOp_NOP = no operation), but to instead follow the new logical instructions listed below the NOP. The LogOp_GetIdx (full read of an index) goes into group 21, and the LogOp_SelectIdx (selection on an index) is placed in group 22, operating on the result of group 21. The definition of the comparison ‘the Year = 2013’ (ScaOp_Comp downwards) was already present in the memo starting at group 2, so no new memo groups are created for that. New Cardinality Estimates The new memo groups require two new cardinality estimates to be derived. First, LogOp_Idx (full read of the index) gets a predicted cardinality of 10,436. This number comes from the filtered index statistics: DBCC SHOW_STATISTICS (Calendar, Weekends) WITH STAT_HEADER; The second new cardinality derivation is for the LogOp_SelectIdx applying the predicate (theYear = 2013). To get a number for this, the cardinality estimator uses statistics for the column ‘theYear’, producing an estimate of 365 rows (there are 365 days in 2013!): DBCC SHOW_STATISTICS (Calendar, theYear) WITH HISTOGRAM; This is where the mistake happens. Cardinality estimation should have used the filtered index statistics here, to get an estimate of 104 rows: DBCC SHOW_STATISTICS (Calendar, Weekends) WITH HISTOGRAM; Unfortunately, the logic has lost sight of the link between the read of the filtered index (LogOp_GetIdx) in group 22, and the selection on that index (LogOp_SelectIdx) that it is deriving a cardinality estimate for, in group 21. The correct cardinality estimate (104 rows) is still present in the memo, attached to group 8, but that group now has a PhyOp_NOP implementation. Skipping over the rest of cost-based optimization (in a belated attempt at brevity) we can see the optimizer’s final output using trace flag 8607: This output shows the (incorrect, but understandable) 365 row estimate for the index range operation, and the correct 104 estimate still attached to its PhyOp_NOP. This tree still has to go through a few post-optimizer rewrites and ‘copy out’ from the memo structure into a tree suitable for the execution engine. One step in this process removes PhyOp_NOP, discarding its 104-row cardinality estimate as it does so. To finish this section on a more positive note, consider what happens if we add an OVER clause to the query aggregate. This isn’t intended to be a ‘fix’ of any sort, I just want to show you that the 104 estimate can survive and be used if later cardinality estimation needs it: SELECT Days = COUNT_BIG(*) OVER () FROM dbo.Calendar AS C WHERE theYear = 2013 AND isWeekday = 0; The estimated execution plan is: Note the 365 estimate at the Index Seek, but the 104 lives again at the Segment! We can imagine the lost predicate ‘isWeekday = 0’ as sitting between the seek and the segment in an invisible Filter operator that drops the estimate from 365 to 104. Even though the NOP group is removed after optimization (so we don’t see it in the execution plan) bear in mind that all cost-based choices were made with the 104-row memo group present, so although things look a bit odd, it shouldn’t affect the optimizer’s plan selection. I should also mention that we can work around the estimation issue by including the index’s filtering columns in the index key: CREATE NONCLUSTERED INDEX Weekends ON dbo.Calendar(theYear, isWeekday) WHERE isWeekday = 0 WITH (DROP_EXISTING = ON); There are some downsides to doing this, including that changes to the isWeekday column may now require Halloween Protection, but that is unlikely to be a big problem for a static calendar table ;)  With the updated index in place, the original query produces an execution plan with the correct cardinality estimation showing at the Index Seek: That’s all for today, remember to let me know about any Switch plans you come across on a modern instance of SQL Server! Finally, here are some other posts of mine that cover other plan operators: Segment and Sequence Project Common Subexpression Spools Why Plan Operators Run Backwards Row Goals and the Top Operator Hash Match Flow Distinct Top N Sort Index Spools and Page Splits Singleton and Range Seeks Bitmaps Hash Join Performance Compute Scalar © 2013 Paul White – All Rights Reserved Twitter: @SQL_Kiwi

• how to change a button into a imagebutton in asp.net c#

• Occasional Date or timezone discrepancy in hudson or maven with jodatime

  - by TheStijn

  hi, I hope following explanation will make sense because it's a weird problem we're facing and hard to describe. We have a maven project which gets build in hudson and that contains some unit tests where dates are used and asserted. The hudson server runs on solaris. Now, occasionally (like 30% of the times) the unit tests using dates fail because 3,5 hours are deducted from the specified time in the unit test and hence asserts start failing. The other 70% everything works fine although nothing at all changed in the code and we run the hudson job several times an hour. I add following code to a unittest to check the time: @Test public void testDate() { System.out.println("new DateMidnight(2011, 1, 5).toDate();"); System.out.println(new DateMidnight(2011, 1, 5).toDate()); System.out.println(new DateMidnight(2011, 1, 5).toDate().getTime()); Calendar cal = Calendar.getInstance(); cal.set(Calendar.YEAR, 2011); cal.set(Calendar.MONTH, 0); cal.set(Calendar.DAY_OF_MONTH, 5); cal.set(Calendar.HOUR, 0); cal.set(Calendar.MINUTE, 0); cal.set(Calendar.SECOND, 0); cal.set(Calendar.MILLISECOND, 0); System.out.println("cal.getTime();"); System.out.println(cal.getTime()); System.out.println(cal.getTime().getTime()); } So basically it should print the same thing when using jodatime or plain old Calendar. This is the case in 70% of the runs; for the other 30% I get following printouts: Running TestSuite new DateMidnight(2011, 1, 5).toDate(); Tue Jan 04 21:30:00 MET 2011 1294173000000 cal.getTime(); Wed Jan 05 12:00:00 MET 2011 1294225200000 Local maven tests never appear the pose this problem and we can't figure out what could be the cause of it. Especially, we can't think of a single reason why the tests sometimes pass and sometimes fail without changing any code nor hudson or server setting. Also, we run the maven install with cobertura which means that the unit tests are run twice. It happens also that they pass the first time and fail the second time or the other way around or that they fail both times. Thanks for any help, Stijn

• Using MySQL to generate daily sales reports with filled gaps, grouped by currency

  - by Shane O'Grady

  I'm trying to create what I think is a relatively basic report for an online store, using MySQL 5.1.45 The store can receive payment in multiple currencies. I have created some sample tables with data and am trying to generate a straightforward tabular result set grouped by date and currency so that I can graph these figures. I want to see each currency that is available per date, with a 0 in the result if there were no sales in that currency for that day. If I can get that to work I want to do the same but also grouped by product id. In the sample data I have provided there are only 3 currencies and 2 product ids, but in practice there can be any number of each. I can correctly group by date, but then when I add a grouping by currency my query does not return what I want. I based my work off this article. My reporting query, grouped only by date: SELECT calendar.datefield AS date, IFNULL(SUM(orders.order_value),0) AS total_value FROM orders RIGHT JOIN calendar ON (DATE(orders.order_date) = calendar.datefield) WHERE (calendar.datefield BETWEEN (SELECT MIN(DATE(order_date)) FROM orders) AND (SELECT MAX(DATE(order_date)) FROM orders)) GROUP BY date Now grouped by date and currency: SELECT calendar.datefield AS date, orders.currency_id, IFNULL(SUM(orders.order_value),0) AS total_value FROM orders RIGHT JOIN calendar ON (DATE(orders.order_date) = calendar.datefield) WHERE (calendar.datefield BETWEEN (SELECT MIN(DATE(order_date)) FROM orders) AND (SELECT MAX(DATE(order_date)) FROM orders)) GROUP BY date, orders.currency_id The results I am getting (grouped by date and currency): +------------+-------------+-------------+ | date | currency_id | total_value | +------------+-------------+-------------+ | 2009-08-15 | 3 | 81.94 | | 2009-08-15 | 45 | 25.00 | | 2009-08-15 | 49 | 122.60 | | 2009-08-16 | NULL | 0.00 | | 2009-08-17 | 45 | 25.00 | | 2009-08-17 | 49 | 122.60 | | 2009-08-18 | 3 | 81.94 | | 2009-08-18 | 49 | 245.20 | +------------+-------------+-------------+ The results I want: +------------+-------------+-------------+ | date | currency_id | total_value | +------------+-------------+-------------+ | 2009-08-15 | 3 | 81.94 | | 2009-08-15 | 45 | 25.00 | | 2009-08-15 | 49 | 122.60 | | 2009-08-16 | 3 | 0.00 | | 2009-08-16 | 45 | 0.00 | | 2009-08-16 | 49 | 0.00 | | 2009-08-17 | 3 | 0.00 | | 2009-08-17 | 45 | 25.00 | | 2009-08-17 | 49 | 122.60 | | 2009-08-18 | 3 | 81.94 | | 2009-08-18 | 45 | 0.00 | | 2009-08-18 | 49 | 245.20 | +------------+-------------+-------------+ The schema and data I am using in my tests: CREATE TABLE orders ( id INT PRIMARY KEY AUTO_INCREMENT, order_date DATETIME, order_id INT, product_id INT, currency_id INT, order_value DECIMAL(9,2), customer_id INT ); INSERT INTO orders (order_date, order_id, product_id, currency_id, order_value, customer_id) VALUES ('2009-08-15 10:20:20', '123', '1', '45', '12.50', '322'), ('2009-08-15 12:30:20', '124', '1', '49', '122.60', '400'), ('2009-08-15 13:41:20', '125', '1', '3', '40.97', '324'), ('2009-08-15 10:20:20', '126', '2', '45', '12.50', '345'), ('2009-08-15 13:41:20', '131', '2', '3', '40.97', '756'), ('2009-08-17 10:20:20', '3234', '1', '45', '12.50', '1322'), ('2009-08-17 10:20:20', '4642', '2', '45', '12.50', '1345'), ('2009-08-17 12:30:20', '23', '2', '49', '122.60', '3142'), ('2009-08-18 12:30:20', '2131', '1', '49', '122.60', '4700'), ('2009-08-18 13:41:20', '4568', '1', '3', '40.97', '3274'), ('2009-08-18 12:30:20', '956', '2', '49', '122.60', '3542'), ('2009-08-18 13:41:20', '443', '2', '3', '40.97', '7556'); CREATE TABLE currency ( id INT PRIMARY KEY, name VARCHAR(255) ); INSERT INTO currency (id, name) VALUES (3, 'Euro'), (45, 'US Dollar'), (49, 'CA Dollar'); CREATE TABLE calendar (datefield DATE); DELIMITER | CREATE PROCEDURE fill_calendar(start_date DATE, end_date DATE) BEGIN DECLARE crt_date DATE; SET crt_date=start_date; WHILE crt_date < end_date DO INSERT INTO calendar VALUES(crt_date); SET crt_date = ADDDATE(crt_date, INTERVAL 1 DAY); END WHILE; END | DELIMITER ; CALL fill_calendar('2008-01-01', '2011-12-31');

• How can I prevent a textbox from taking focus on the postback when I have a calendar extender on it?

  - by Biff MaGriff

  Hello, I have repeater, inside this repeater is a user control. In my c# codebehind on my user control I dynamically add a textbox and assign a calendar extender to it. Similar to this. //custom control protected void Page_Load(object o, EventArgs e) { TextBox tb = new TextBox(); tb.ID = "myTextBox"; MaskedEditExtender meeDate = new MaskedEditExtender(); meeDate.ID = "meeDate"; meeDate.TargetControlID = this.UniqueID + "$" + tb.ID; meeDate.Mask = "99/99/9999"; meeDate.MaskType = MaskedEditType.Date; CalendarExtender ce = new CalendarExtender(); ce.ID = "ceCalendar"; ce.TargetControlID = this.UniqueID + "$" + tb.ID; this.Controls.Add(tbDate); this.Controls.Add(meeDate); this.Controls.Add(ce); } This works well, however after I postback the textbox takes focus and the calendar extender fires and it looks really.... dumb. How can I stop this?

• How can I create a weekly calendar view for an Android Honeycomb application?

  - by BVB

  I am working on an Android (v3.0) application that has a requirement of mimicking the weekly calendar layout found on Google Calendar: The events will be based on external requests through the Google Calendar API (I already have this part working). Using the API, I can obtain a list of events for the week, with each event having a starting and and ending datetime. I would like to use this data to show the scheduled events to the application's users in a view similar to the one above. Here's what I have so far: The XML appears below: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="800dp" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"

</RelativeLayout> </ScrollView> </LinearLayout> My approach was to make 40dp equal to 1 hr of time. Thus, whenever I would like to add an event that has a duration of 1.5 hours, I will make an 60dp button that I will place at the exact location that the time begins (12am = 0dp from the top, 1pm = 40dp from the top, 2pm = 80d from the top, etc). My questions are: Is there a better way of doing this? How can I convert my XML to be stand-alone view that could be added to any Android project? (I plan on perhaps making a blog post about the end product) Thank you!

  - by Haroldo

  I'm building a simple calendar for holiday cottages to show when they are booked or available. What would be the fastest mysql table design for this, bearing in mind when users mark dates as available/booked they will do so via a start date and an end date. i can see 2 obvious options Store 'booked' data for every day [more rows] or, store 'booked' data with 2 columns a start_date and end_date [more processing?] Which is best or is there another method i'm missing?
