  • C# - using decimal in switch impossible?

    - by phobia
    Hi, I'm justing starting out learning C# and I've become stuck at something very basic. For my first "app" I thought I'd go for something simple, so I decided for a BMI calculator. The BMI is calculated into a decimal type which I'm now trying to use in a switch statement, but aparently decimal can't be used in a switch? What would be the C# solution for this: decimal bmi = calculate_bmi(h, w); switch (bmi) { case < 18.5: bmi_description = "underweight."; break; case > 25: bmi_description = "overweight"; case > 30: bmi_description = "very overweight"; case > 40: bmi_description = "extreme overweight"; break; } Thanks in advance :)

  • How can I make TextToSpeech to speak a text with max volume and restore original volume after speak end?

    - by HelloCW
    I save the current volume both STREAM_RING and STREAM_MUSIC before sTts.get().speak(s, TextToSpeech.QUEUE_ADD, null), I hope the TextToSpeech can speak a text with max volume, but in fact I find the TextToSpeech speak the text with current volume, it seems that sTts.get().speak is asynchronous. How can I make TextToSpeech to speak a text with max volume and restore original volume after speak end? Thanks! public class SpeechTxt { private static SoftReference<TextToSpeech> sTts; public static void SpeakOut(final Context context, final String s) { final Context appContext = context.getApplicationContext(); if (sTts == null) { sTts = new SoftReference<TextToSpeech>(new TextToSpeech(appContext, new TextToSpeech.OnInitListener() { @Override public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { speak(appContext, s); } else { } } })); } else { speak(appContext, s); } } private static void speak(Context context, String s) { if (sTts != null) { switch (sTts.get().setLanguage(Locale.getDefault())) { case TextToSpeech.LANG_COUNTRY_AVAILABLE: case TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE: case TextToSpeech.LANG_AVAILABLE: { sTts.get().setPitch((float) 0.6); sTts.get().setSpeechRate((float) 0.8); int currentRing=PublicParFun.GetCurrentVol(context, AudioManager.STREAM_RING); int currentPlay=PublicParFun.GetCurrentVol(context, AudioManager.STREAM_MUSIC); PublicParFun.SetRingVol(context, 0); PublicParFun.SetPlayVol(context,1000000); sTts.get().speak(s, TextToSpeech.QUEUE_ADD, null); PublicParFun.SetRingVol(context, currentRing); PublicParFun.SetPlayVol(context,currentPlay); break; } case TextToSpeech.LANG_MISSING_DATA: { break; } case TextToSpeech.LANG_NOT_SUPPORTED: // not much to do here } } } public static int GetCurrentVol(Context myContext,int streamType){ AudioManager mAudioManager = (AudioManager)myContext.getSystemService(Context.AUDIO_SERVICE); int current = mAudioManager.getStreamVolume( streamType); return current; } public static void SetRingVol(Context myContext,int vol){ SetVol(myContext,AudioManager.STREAM_RING, vol); } public static void SetPlayVol(Context myContext,int vol){ SetVol(myContext,AudioManager.STREAM_MUSIC, vol); } private static void SetVol(Context myContext,int streamType,int vol){ AudioManager mAudioManager = (AudioManager)myContext.getSystemService(Context.AUDIO_SERVICE); int max = mAudioManager.getStreamMaxVolume(streamType); if (vol>max){ vol=max; } mAudioManager.setStreamVolume(streamType,vol, 0); } }

  • TableViewCell autorelease error

    - by iAm
    OK, for two days now i have been trying to solve an error i have inside the cellForRowAtIndex method, let start by saying that i have tracked down the bug to this method, the error is [CFDictionary image] or [Not a Type image] message sent to deallocated instance. I know about the debug flags, NSZombie, MallocStack, and others, they helped me narrow it down to this method and why, but I do not know how to solve besides a redesign of the app UI. SO what am i trying to do, well for this block of code, displays a purchase detail, which contains items, the items are in there own section, now when in edit mode, there appears a cell at the bottom of the items section with a label of "Add new Item", and this button will present a modal view of the add item controller, item is added and the view returns to the purchase detail screen, with the just added item in the section just above the "add new Item" cell, the problem happens when i scroll the item section off screen and back into view the app crashes with EXC_BAD_ACCESS, or even if i don't scroll and instead hit the back button on the navBar, still the same error. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case PURCHASE_SECTION: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } switch (indexPath.row) { case CATEGORY_ROW: cell.textLabel.text = @"Category:"; cell.detailTextLabel.text = [self.purchase.category valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case TYPE_ROW: cell.textLabel.text = @"Type:"; cell.detailTextLabel.text = [self.purchase.type valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case VENDOR_ROW: cell.textLabel.text = @"Payment:"; cell.detailTextLabel.text = [self.purchase.vendor valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case NOTES_ROW: cell.textLabel.text = @"Notes"; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; default: break; } break; } case ITEMS_SECTION: { NSUInteger itemsCount = [items count]; if (indexPath.row < itemsCount) { static NSString *itemsCellID = @"ItemsCell"; cell = [tableView dequeueReusableCellWithIdentifier:itemsCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:itemsCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } singleItem = [self.items objectAtIndex:indexPath.row]; cell.textLabel.text = singleItem.name; cell.detailTextLabel.text = [singleItem.amount formattedDataDisplay]; cell.imageView.image = [singleItem.image image]; } else { static NSString *AddItemCellID = @"AddItemCell"; cell = [tableView dequeueReusableCellWithIdentifier:AddItemCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddItemCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } cell.textLabel.text = @"Add Item"; } break; } case LOCATION_SECTION: { static NSString *localID = @"LocationCell"; cell = [tableView dequeueReusableCellWithIdentifier:localID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:localID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } cell.textLabel.text = @"Purchase Location"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; } default: break; } return cell; } the singleItem is of Modal Type PurchaseItem for core data now that i know what is causing the error, how do i solve it, I have tried everything that i know and some of what i dont know but still, no progress, please any suggestions as to how to solve this without redesign is my goal, perhaps there is an error i am doing that I cannot see, but if it's the nature of autorelease, than i will redesign.

  • How to simplify this php switch statement?

    - by janoChen
    I would like to change this: // use appropiate lang.xx.php file according to the value of the $lang switch ($_SESSION['lang']) { case 'en': $lang_file = 'lang.en.php'; break; case 'es': $lang_file = 'lang.es.php'; break; case 'zh-tw': $lang_file = 'lang.zh-tw.php'; break; case 'zh-cn': $lang_file = 'lang.zh-cn.php'; break; default: $lang_file = 'lang.en.php'; } into something like this: //include file for final output include_once 'languages/lang.'.$_SESSION['lang'].'php; So that I can skip the whole switch part. I tried other combinations but they don't seem to work. Any suggestions?

  • CSS-Specifity and CSS Inheritance (concrete question)?

    - by jens
    Hello, i would by thankful for an official link (and section) of the specification for CSS, that explains if: .one two h1 {color:green;font-family:arial;} /*case 1 */ .one two h1 {color:blue;} /*case 2*/ will result in (when evaluated by the browser) .one two h1 {color:blue;font-family:arial;} /*case 3*/ or will it be: .one two h1 {color:blue;} /*case 4*/ ==I have read a lot about inheritance, specifity, cascading etc but I still have not found for the given example which rules apply here. In regard to specifity both elements are equal in specifity the case2 will be the most specify one (as it is equal specific but the last one). But does specifity always apply to the whole selector with ALL properties defined. Or only the the properties that are are in "competition" (and declared in both). thanks!!!!

  • Creating a System::String object from a BSTR in Managed C++ - is this way a good idea???

    - by Eli
    My co-worker is filling a System::String object with double-byte characters from an unmanaged library by the following method: RFC_PARAMETER aux; Object* target; RFC_UNICODE_TYPE_ELEMENT* elm; elm = &(m_coreObject->m_pStructMeta->m_typeElements[index]); aux.name = NULL; aux.nlen = 0; aux.type = elm->type; aux.leng = elm->c2_length; aux.addr = m_coreObject->m_rfcWa + elm->c2_offset; GlobalFunctions::CreateObjectForRFCField(target,aux,elm->decimals); GlobalFunctions::ReadRFCField(target,aux,elm->decimals); Where GlobalFunctions::CreateObjectForRFCField creates a System::String object filled with spaces (for padding) to what the unmanaged library states the max length should be: static void CreateObjectForRFCField(Object*& object, RFC_PARAMETER& par, unsigned dec) { switch (par.type) { case TYPC: object = new String(' ',par.leng / sizeof(_TCHAR)); break; // unimportant afterwards. } } And GlobalFunctions::ReadRFCField() copies the data from the library into the created String object and preserves the space padding: static void ReadRFCField(String* target, RFC_PARAMETER& par) { int lngt; _TCHAR* srce; switch (par.type) { case TYPC: case TYPDATE: case TYPTIME: case TYPNUM: lngt = par.leng / sizeof(_TCHAR); srce = (_TCHAR*)par.addr; break; case RFCTYPE_STRING: lngt = (*(_TCHAR**)par.addr != NULL) ? (int)_tcslen(*(_TCHAR**)par.addr) : 0; srce = *(_TCHAR**)par.addr; break; default: throw new DotNet_Incomp_RFCType2; } if (lngt > target->Length) lngt = target->Length; GCHandle gh = GCHandle::Alloc(target,GCHandleType::Pinned); wchar_t* buff = reinterpret_cast<wchar_t*>(gh.AddrOfPinnedObject().ToPointer()); _wcsnset(buff,' ',target->Length); _snwprintf(buff,lngt,_T2WFSP,srce); gh.Free(); } Now, on occasion, we see access violations getting thrown in the _snwprintf call. My question really is: Is it appropriate to create a string padded to a length (ideally to pre-allocate the internal buffer), and then to modify the String using GCHandle::Alloc and the mess above. And yes, I know that System::String objects are supposed to be immutable - I'm looking for a definitive "This is WRONG and here is why". Thanks, Eli.

  • Convert a List of Options to an Option of List using Scalaz

    - by Rafael de F. Ferreira
    The following function transforms a list of Option[T] into a list of Some[T], in the case where all members are Some's, or None, in the case where there is at least one None member. I guess the code is clearer that this explanation: def lo2ol[T](lo: List[Option[T]]): Option[List[T]] = { lo.foldRight[Option[List[T]]](Some(Nil)){(o, ol) => (o, ol) match { case (Some(x), Some(xs)) => Some(x :: xs); case _ => None : Option[List[T]]; }}} I remember seeing somewhere a similar example, but using Scalaz to simplify the code. How would it look like?

  • Conway's Game of Life - C++ and Qt

    - by Jeff Bridge
    I've done all of the layouts and have most of the code written even. But, I'm stuck in two places. 1) I'm not quite sure how to set up the timer. Am I using it correctly in the gridwindow class? And, am I used the timer functions/signals/slots correctly with the other gridwindow functions. 2) In GridWindow's timerFired() function, I'm having trouble checking/creating the vector-vectors. I wrote out in the comments in that function exactly what I am trying to do.

  • Non RBAC User Roles and Permissions System: checking the user's City

    - by micha12
    We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case, this being the first post. We have the following case: not to allow a user view a certain page if the user lives in a particular city. This is a simple case that is coded in the following way: if (User.City == “Moscow”) // Allow the user to view the page. else // Do not allow the user to view this page. Though this case is very simple and straightforward, it has nothing to do with the RBAC. On StackOverflow, someone called this an Attribute-based Access Control. Under the classical RBAC, it seems that this case should be designed like this: introduce a permission “City where the person lives”, this permission will have a property City. Then create a role, add a permission of type “City = Moscow” to it and the assign the role to the user. Looks extremely cumbersome. The question is whether it is acceptable to introduce such non-RBAC approaches to our permissions system – does that break the design or not? This might seem a primitive question, but we found that most applications use pure RBAC, and we started to think that we might be doing something wrong. Thank you.

  • Is there a better way to convert SQL datetime from hh:mm:ss to hhmmss?

    - by Johann J.
    I have to write an SQL view that returns the time part of a datetime column as a string in the format hhmmss (apparently SAP BW doesn't understand hh:mm:ss). This code is the SAP recommended way to do this, but I think there must be a better, more elegant way to accomplish this TIME = case len(convert(varchar(2), datepart(hh, timecolumn))) when 1 then /* Hour Part of TIMES */ case convert(varchar(2), datepart(hh, timecolumn)) when '0' then '24' /* Map 00 to 24 ( TIMES ) */ else '0' + convert(varchar(1), datepart(hh, timecolumn)) end else convert(varchar(2), datepart(hh, timecolumn)) end + case len(convert(varchar(2), datepart(mi, timecolumn))) when 1 then '0' + convert(varchar(1), datepart(mi, timecolumn)) else convert(varchar(2), datepart(mi, timecolumn)) end + case len(convert(varchar(2), datepart(ss, timecolumn))) when 1 then '0' + convert(varchar(1), datepart(ss, timecolumn)) else convert(varchar(2), datepart(ss, timecolumn)) end This accomplishes the desired result, 21:10:45 is displayed as 211045. I'd love for something more compact and easily readable but so far I've come up with nothing that works.

  • Serializing Class Derived from Generic Collection yet Deserializing the Generic Collection

    - by Stacey
    I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored. When called like this... var titles = Repository.List<Models.Title>(); I get the exception <Titlesxmlns=''> was not expected. The XML is formatted such as. .. <?xml version="1.0" encoding="utf-16"?> <Titles xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Title> <Id>442daf7d-193c-4da8-be0b-417cec9dc1c5</Id> </Title> </Titles> Here is the deserialization code. public static T Deserialize<T>(String xmlString) { System.Xml.Serialization.XmlSerializer XmlFormatSerializer = new System.Xml.Serialization.XmlSerializer(typeof(T)); StreamReader XmlStringReader = new StreamReader(xmlString); //XmlTextReader XmlFormatReader = new XmlTextReader(XmlStringReader); try { return (T)XmlFormatSerializer.Deserialize(XmlStringReader); } catch (Exception e) { throw e; } finally { XmlStringReader.Close(); } }

  • PagerView overlapping PagerTabStrip / PagerTitleStrip

    - by user1256169
    I've been trying for about a week to get my PagerView not to overlap the TitleStrip. I've tried absolutely everything I can think of, and one StackOverflow question that looked like the same question, had an answer that wasn't applicable. It appears that both the PagerTitleStrip and the TextView start at 0,0 (left,top) Any help would be appreciated. Note that I can't use any XML (inc Layout.xml) so it's all done programatically. Here's a full working example of my problem: package com.example.projname; import android.app.Activity; import android.os.Bundle; import android.support.v4.view.PagerAdapter; import android.support.v4.view.PagerTabStrip; import android.support.v4.view.ViewPager; import android.view.Gravity; import android.view.View; import android.view.ViewGroup; import android.view.ViewGroup.LayoutParams; import android.widget.TextView; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); MyPagerAdapter myPagerAdapter = new MyPagerAdapter(); PagerTabStrip myPagerTabStrip = new PagerTabStrip(this); myPagerTabStrip.setGravity(Gravity.TOP); ViewPager viewPager = new ViewPager(this); viewPager.addView(myPagerTabStrip, LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); viewPager.setAdapter(myPagerAdapter); setContentView(viewPager); } class MyPagerAdapter extends PagerAdapter { public final String[] Titles = { "Title One", "Title Two", "Title Three", "Title Four", "Title Five" }; @Override public int getCount() { return Titles.length; } @Override public boolean isViewFromObject(View view, Object object) { return (view == object); } @Override public CharSequence getPageTitle(int position) { return Titles[position]; } @Override public Object instantiateItem(ViewGroup container, int position) { TextView textView = new TextView(getApplicationContext()); String myString = new String("Page " + (position + 1) + "\r\n"); textView.setText(myString + myString + myString + myString + myString + myString); container.addView(textView); return textView; } @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView((View) object); } } } Edit: Adding a screenshot of the problem:

  • Capture *all* display-characters in JavaScript?

    - by Jean-Charles
    I was given an unusual request recently that I'm having the most difficult time addressing that involves capturing all display-characters when typed into a text box. The set up is as follows: I have a text box that has a maxlength of 10 characters. When the user attempts to type more than 10 characters, I need to notify the user that they're typing beyond the character count limit. The simplest solution would be to specify a maxlength of 11, test the length on every keyup, and truncate back down to 10 characters but this solution seems a bit kludgy. What I'd prefer to do is capture the character before keyup and, depending on whether or not it is a display-character, present the notification to the user and prevent the default action. A white-list would be challenging since we handle a lot of international data. I've played around with every combination of keydown, keypress, and keyup, reading event.keyCode, event.charCode, and event.which, but I can't find a single combination that works across all browsers. The best I could manage is the following that works properly in =IE6, Chrome5, FF3.6, but fails in Opera: NOTE: The following code utilizes jQuery. $(function(){ $('#textbox').keypress(function(e){ var $this = $(this); var key = ('undefined'==typeof e.which?e.keyCode:e.which); if ($this.val().length==($this.attr('maxlength')||10)) { switch(key){ case 13: //return case 9: //tab case 27: //escape case 8: //backspace case 0: //other non-alphanumeric break; default: alert('no - '+e.charCode+' - '+e.which+' - '+e.keyCode); return false; }; } }); }); I'll grant that what I'm doing is likely over-engineering the solution but now that I'm invested in it, I'd like to know of a solution. Thanks for your help!

  • handling NSStream events when using EASession in MonoTouch

    - by scotru
    Does anyone have an example of how to handle read and write NSStream events in Monotouch when working with accessories via EASession? It looks like there isn't a strongly typed delegate for this and I'm having trouble figuring out what selectors I need to handle on the delegates of my InputStream and OutputStream and what I actually need to do with each selector in order to properly fill and empty the buffers belonging to the EASession object. Basically, I'm trying to port Apple's EADemo app to Monotouch right now. Here's the Objective-C source that I think is relevant to this problem: / / asynchronous NSStream handleEvent method - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { switch (eventCode) { case NSStreamEventNone: break; case NSStreamEventOpenCompleted: break; case NSStreamEventHasBytesAvailable: [self _readData]; break; case NSStreamEventHasSpaceAvailable: [self _writeData]; break; case NSStreamEventErrorOccurred: break; case NSStreamEventEndEncountered: break; default: break; } } / low level write method - write data to the accessory while there is space available and data to write - (void)_writeData { while (([[_session outputStream] hasSpaceAvailable]) && ([_writeData length] > 0)) { NSInteger bytesWritten = [[_session outputStream] write:[_writeData bytes] maxLength:[_writeData length]]; if (bytesWritten == -1) { NSLog(@"write error"); break; } else if (bytesWritten > 0) { [_writeData replaceBytesInRange:NSMakeRange(0, bytesWritten) withBytes:NULL length:0]; } } } // low level read method - read data while there is data and space available in the input buffer - (void)_readData { #define EAD_INPUT_BUFFER_SIZE 128 uint8_t buf[EAD_INPUT_BUFFER_SIZE]; while ([[_session inputStream] hasBytesAvailable]) { NSInteger bytesRead = [[_session inputStream] read:buf maxLength:EAD_INPUT_BUFFER_SIZE]; if (_readData == nil) { _readData = [[NSMutableData alloc] init]; } [_readData appendBytes:(void *)buf length:bytesRead]; //NSLog(@"read %d bytes from input stream", bytesRead); } [[NSNotificationCenter defaultCenter] postNotificationName:EADSessionDataReceivedNotification object:self userInfo:nil]; } I'd also appreciate any architectural recommendations on how to best implement this in monotouch. For example, in the Objective C implementation these functions are not contained in any class--but in Monotouch would it make sense to make them members of my

  • enclosing double quotes in array

    - by Jared
    Hi all I might be looking at this the wrong way, but I have a form that does its thing (sends emails etc etc) but I also put in some code to make a simple flatfile csv log with some of the user entered details. If a user accidentally puts in for instance 'himynameis","bob' this would either break the csv row (because the quotes weren't encapsulated) or if I use htmlspecialchars() and stripslashes() on the data, I end up with a ugly data value of 'himynameis&quot;,&quot;bob'. My question is, how can I handle the incoming data to cater for '"' being put in the form without breaking my csv file? this is my code for creating the csv log file. @$name = htmlspecialchars(trim($_POST['name'])); @$emailCheck = htmlspecialchars(trim($_POST['email'])); @$title = htmlspecialchars(trim($_POST['title'])); @$phone = htmlspecialchars(trim($_POST['phone'])); function logFile($logText) { $path = 'D:\logs'; $filename = '\Log-' . date('Ym', time()) . '.csv'; $file = $path . $filename; if(!file_exists($file)) { $logHeader = array('Date', 'IP_Address', 'Title', 'Name', 'Customer_Email', 'Customer_Phone', 'file'); $fp = fopen($file, 'a'); fputcsv($fp, $line); } $fp = fopen($file, 'a'); foreach ($logText as $record) { fputcsv($fp, $record); } } //Log submission to file $date = date("Y/m/d H:i:s"); $clientIp = getIpAddress(); //get clients IP address $nameLog = stripslashes($name); $titleLog = stripslashes($title); if($_FILES['uploadedfile']['error'] == 4) $filename = "No file attached."; //check if file uploaded and return $logText = array(array("$date", "$clientIp", "$titleLog", "$nameLog", "$emailCheck", "$phone", "$filename")); logFile($logText); //write form details to log Here is a sample of the incoming array data: Array ( [0] => Array ( [0] => 2010/05/17 10:22:27 [1] => xxx.xxx.xxx.xxx [2] => title [3] => """"himynameis","bob" [4] => [email protected] [5] => 346346 [6] => No file attached. ) ) TIA Jared

  • Dynamically create categories for SQLite pivot/crosstab

    - by alj
    I realise it is possible to create a crosstab within sqlite, but is it possible to dynamically determine the relevant categories/columns at runtime rather than hardcoding them? Given the following example, it can get rather tedious ... SELECT shop_id, sum(CASE WHEN product = 'Fiesta' THEN units END) as Fiesta, sum(CASE WHEN product = 'Focus' THEN units END) as Focus, sum(CASE WHEN product = 'Puma' THEN units END) as Puma, sum(units) AS total FROM sales GROUP BY shop_id I managed to do this in SQLServer in a stored proceedure before and wondered if there was anything equivalent.
