• SQLite vs Firebird

  - by rwallace

  The scenario I'm looking at is "This program uses Postgres. Oh, you want to just use it single-user for the moment, and put off having to deal with installing a database server? Okay, in the meantime you can use it with the embedded single-user database." The question is then which embedded database is best. As I understand it, the two main contenders are SQLite and Firebird; so which is better? Criteria: Full SQL support, or as close as reasonably possible. Full text search. Easy to call from C# Locks, or allows you to lock, the database file to make sure nobody tries to run it multiuser and ends up six months down the road with intermittent data corruption in all their backups. Last but far from least, reliability. As I understand it, the disadvantages of SQLite are, No right outer join. Workaround: use left outer join instead. Not much integrity checking. Workaround: be really careful in the application code. No decimal numbers. Workaround: lots of aspirin. None of the above are showstoppers. Are there any others I'm missing? (I know it doesn't support some administrative and code-within-database SQL features, that aren't relevant for this kind of use case.) I don't know anything much about Firebird. What are its disadvantages?

• Get Alfresco extension properties with OpenCMIS

  - by AJPerez

  I'm writing an OpenCMIS based application, which extracts some data from Alfresco 3.3. It works fine with standard CMIS properties such as cmis:name or cmis:contentStreamMimeType; however, I can't access Alfresco especific properties, which are present on the CMIS AtomPub feed as "Alfresco extensions": <cmisra:object> <cmis:properties> <cmis:propertyString propertyDefinitionId="cmis:name" displayName="Name" queryName="cmis:name"> <cmis:value>test document</cmis:value> </cmis:propertyString> <cmis:propertyString propertyDefinitionId="cmis:contentStreamMimeType" displayName="Content Stream MIME Type" queryName="cmis:contentStreamMimeType"> <cmis:value>text/html</cmis:value> </cmis:propertyString> ... <alf:aspects> ... <alf:properties> <cmis:propertyString propertyDefinitionId="cm:description" displayName="Description" queryName="cm:description"> <cmis:value>This is just a test document</cmis:value> </cmis:propertyString> </alf:properties> </alf:aspects> </cmis:properties> </cmisra:object> Is there any way in which I can get the value of cm:descripcion, with OpenCMIS? My guess is that I need to use the DocumentType interface instead of Document, and then call its getExtensions() method. But I don't know how to get an instance of DocumentType. Any help would be really appreciated. Regards Edit: altough Florian's answer already worked out for me, I've just realized that I can get these properties' values with CMIS SQL, too: select d.*, t.*, a.* from cmis:document d join cm:titled t on d.cmis:objectid = t.cmis:objectid join cm:author a on d.cmis:objectid = a.cmis:objectid where t.cm:description like ...

• Laravel - Paginate and get()

  - by Bajongskie

  With the code below, what I wanted was paginate the query I created. But, when I try to add paginate after get, it throws an error. I wanted to remain get since I want to limit to columns that was set on $fields. What would should be the better idea to paginate this thing? or what's a good substitute for get and limit the columns? What I tried: ->get($this->fields)->paginate($this->limit) Part of my controller: class PhonesController extends BaseController { protected $limit = 5; protected $fields = array('Phones.*','manufacturers.name as manufacturer'); /** * Display a listing of the resource. * * @return Response */ public function index() { if (Request::query("str")) { $phones = Phone::where("model", 'LIKE', '%'. Request::query('str') . '%') ->join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id') ->get($this->fields); } else { $phones = Phone::join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id') ->get($this->fields); } return View::make('phones.index')->with('phones', $phones); } }

• GNU Make: How to call $(wildcard) within $(eval)

  - by bengineerd

  I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I can't seem to get the wildcard function to work within an eval. The basic code I'm having issues with looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $(join $(SRC_DIR), $(1)/) $(1)_SRC_FILES = $(wildcard $$($(1)_SRC_DIR)*.c) endef $(eval $(call PROGRAM_template, $(PROG_NAME))) all: @echo $(test_SRC_DIR) @echo $(test_SRC_FILES) @echo $(wildcard $(wildcard $(test_SRC_DIR)*.c) When I run make with this, the output is ./src/test [correct list of all .c files in ./src/test/] Basically, the wildcard call within PROGRAM_template is not being eval'd as I expect it. The call results in an empty list. The join call is being eval'd correctly though. So, what am I doing wrong? My guess is that $$($(1)_SRC_DIR) is not correct, but I can't figure out the right way to do it. EDIT Once this was solved, it didn't take long for me to hit another issue with eval. I posted it as a new question at http://stackoverflow.com/questions/2428506/workaround-for-gnu-make-3-80-eval-bug

• VS2008 EF and non crud SP usage.

  - by SteveO

  Using an edmx version of EF. My returned data is a join between tables that has a COMPOUND filter on the primary table. In essence this query is going to return a SEGMENT of Law codes and descriptions that a user can tie to a Sex Offender report. I have a complex SP because Linq2SQL cannot pass in a between statement, or at least that is how I understand the error. The Code itself is broken up by '-' marks. 39-13-504 "Aggravated Sexual Battery" User wants to have a query with 4 parmas 39, 13, 500, 599. Get all codes from Title 39 and Chapter 13 with parts between 500 and 599. I have the SP in place to do the work, is there are way to consume the SP within the EF? I find many blogs about SPs with CRUD operations as their use of an SP. That doesn't fit this need at all. I do not have a single table but a join to the "prior selections" table that maps the key for the code. Any pointers on how to get a READ with an SP? TIA

• wp_get_archives(cat=id) <-- Any way to specifiy cat id in archives?

  - by Matrym

  Does anyone know how to specify an INCLUDE ONLY category using wp_get_archives? I would like to specify a category but then list results by month. I've tried kwebble's plugin to no avail. I've also found the following on WP forums, but it appears to only exclude categories. Perhaps it can be modified to do include? Even given that, I'm not sure how I would call it... Thanks in advance! add_filter( 'getarchives_where', 'customarchives_where' ); add_filter( 'getarchives_join', 'customarchives_join' ); function customarchives_join( $x ) { global $wpdb; return $x . " INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)"; } function customarchives_where( $x ) { global $wpdb; $exclude = '1'; // category id to exclude return $x .

• Sql Query - Selecting rows where user can be both friend and user

  - by Gublooo

  Hey Sorry the title is not very clear. This is a follow up to my earlier question where one of the members helped me with a query. I have a following friends Table Friend friend_id - primary key user_id user_id_friend status The way the table is populated is - when I send a friend request to John - my userID appears in user_id and Johns userID appears in user_id_friend. Now another scenario is say Mike sends me a friend request - in this case mike's userID will appear in user_id and my userID will appear in user_id_friend So to find all my friends - I need to run a query to find where my userID appears in both user_id column as well as user_id_friend column What I am trying to do now is - when I search for user say John - I want all users Johns listed on my site to show up along with the status of whether they are my friend or not and if they are not - then show a "Add Friend" button. Based on the previous post - I got this query which does part of the job - My example user_id is 1: SELECT u.user_id, f.status FROM user u LEFT OUTER JOIN friend f ON f.user_id = u.user_id and f.user_id_friend = 1 where u.name like '%' So this only shows users with whom I am friends where they have sent me request ie my userID appears in user_id_friend. Although I am friends with others (where my userID appears in user_id column) - this query will return that as null To get those I need another query like this SELECT u.user_id, f.status FROM user u LEFT OUTER JOIN friend f ON f.user_id_friend = u.user_id and f.user_id = 1 where u.name like '%' So how do I combine these queries to return 1 set of users and what my friendship status with them is. I hope my question is clear Thanks

• Modify Wordpress SQL Query to pull from within a category

  - by Levi

  Hi I am using a wordpress plugin called "kf most read" which stores a count of how many times a post was read, and lets you output a list of most read posts. This works well. The issue is, I am trying to pull the most read posts, but only the most read posts within the current category you are viewing. I am close to clueless when it comes to sql. Here us what the plugin is currently using to pull the most read posts: $sql = "SELECT count(mr.post_ID) as totHits, p.ID, p.post_title from $wpdb-posts p JOIN {$wpdb-prefix}kf_most_read mr on mr.post_ID = p.ID where mr.hit_ts = '".(time() - ( 86400 * $period))."' GROUP BY mr.post_ID order by totHits desc, ID ASC LIMIT $limit"; How could I incorporate the below query which pulls from a specific category into the above? $sql .= "LEFT JOIN $wpdb-term_taxonomy ON($wpdb-term_relationships.term_taxonomy_id = $wpdb-term_taxonomy.term_taxonomy_id)" ; $sql .= "WHERE $wpdb-term_taxonomy.term_id IN ($currentcat)" ; $sql .= "AND $wpdb-term_taxonomy.taxonomy = 'category'" ; Any Help on this would be much appreciated.

• LINQ self referencing query

  - by Chris

  I have the following SQL query: select p1.[id], p1.[useraccountid], p1.[subject], p1.[message], p1.[views], p1.[parentid], case when p2.[created] is null then p1.[created] else p2.[created] end as LastUpdate from forumposts p1 left join ( select parentid, max(created) as [created] from forumposts group by parentid ) p2 on p2.parentid = p1.id where p1.[parentid] is null order by LastUpdate desc Using the following class: public class ForumPost : PersistedObject { public int Views { get; set; } public string Message { get; set; } public string Subject { get; set; } public ForumPost Parent { get; set; } public UserAccount UserAccount { get; set; } public IList<ForumPost> Replies { get; set; } } How would I replicate such a query in LINQ? I've tried several variations, but I seem unable to get the correct join syntax. Is this simply a case of a query that is too complicated for LINQ? Can it be done using nested queries some how? The purpose of the query is to find the most recently updated posts i.e. replying to a post would bump it to the top of the list. Replies are defined by the ParentID column, which is self-referencing.

• SQL Syntax to count unique users completing a task

• Help Converting T-SQL Query to LINQ Query

  - by campbelt

  I am new to LINQ, and so am struggle over some queries that I'm sure are pretty simple. In any case, I have been hiting my head against this for a while, but I'm stumped. Can anyone here help me convert this T-SQL query into a LINQ query? Once I see how it is done, I'm sure I'll have some question about the syntax: SELECT BlogTitle FROM Blogs b JOIN BlogComments bc ON b.BlogID = bc.BlogID WHERE b.Deleted = 0 AND b.Draft = 0 AND b.[Default] = 0 AND bc.Deleted = 0 GROUP BY BlogTitle ORDER BY MAX([bc].[Timestamp]) DESC Just to show that I have tried to solve this on my own, here is what I've come up with so far, though it doesn't compile, let alone work ... var iqueryable = from blog in db.Blogs join blogComment in db.BlogComments on blog.BlogID equals blogComment.BlogID where blog.Deleted == false && blog.Draft == false && blog.Default == false && blogComment.Deleted == false group blogComment by blog.BlogID into blogGroup orderby blogGroup.Max(blogComment => blogComment.Timestamp) select blogGroup;

• Make Python Socket Server More Efficient

  - by BenMills

  I have very little experience working with sockets and multithreaded programming so to learn more I decided to see if I could hack together a little python socket server to power a chat room. I ended up getting it working pretty well but then I noticed my server's CPU usage spiked up over 100% when I had it running in the background. Here is my code in full: http://gist.github.com/332132 I know this is a pretty open ended question so besides just helping with my code are there any good articles I could read that could help me learn more about this? My full code: import select import socket import sys import threading from daemon import Daemon class Server: def __init__(self): self.host = '' self.port = 9998 self.backlog = 5 self.size = 1024 self.server = None self.threads = [] self.send_count = 0 def open_socket(self): try: self.server = socket.socket(socket.AF_INET6, socket.SOCK_STREAM) self.server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) self.server.bind((self.host,self.port)) self.server.listen(5) print "Server Started..." except socket.error, (value,message): if self.server: self.server.close() print "Could not open socket: " + message sys.exit(1) def remove_thread(self, t): t.join() def send_to_children(self, msg): self.send_count = 0 for t in self.threads: t.send_msg(msg) print 'Sent to '+str(self.send_count)+" of "+str(len(self.threads)) def run(self): self.open_socket() input = [self.server,sys.stdin] running = 1 while running: inputready,outputready,exceptready = select.select(input,[],[]) for s in inputready: if s == self.server: # handle the server socket c = Client(self.server.accept(), self) c.start() self.threads.append(c) print "Num of clients: "+str(len(self.threads)) self.server.close() for c in self.threads: c.join() class Client(threading.Thread): def __init__(self,(client,address), server): threading.Thread.__init__(self) self.client = client self.address = address self.size = 1024 self.server = server self.running = True def send_msg(self, msg): if self.running: self.client.send(msg) self.server.send_count += 1 def run(self): while self.running: data = self.client.recv(self.size) if data: print data self.server.send_to_children(data) else: self.running = False self.server.threads.remove(self) self.client.close() """ Run Server """ class DaemonServer(Daemon): def run(self): s = Server() s.run() if __name__ == "__main__": d = DaemonServer('/var/servers/fserver.pid') if len(sys.argv) == 2: if 'start' == sys.argv[1]: d.start() elif 'stop' == sys.argv[1]: d.stop() elif 'restart' == sys.argv[1]: d.restart() else: print "Unknown command" sys.exit(2) sys.exit(0) else: print "usage: %s start|stop|restart" % sys.argv[0] sys.exit(2)

• Hibernate limitations on using variables in queries

  - by sammichy

  I had asked the following question I have the following table structure for a table Player Table Player { Long playerID; Long points; Long rank; } Assuming that the playerID and the points have valid values, can I update the rank for all the players based on the number of points in a single query? If two people have the same number of points, they should tie for the rank. And received the answer from Daniel Vassalo (thank you). UPDATE player JOIN (SELECT p.playerID, IF(@lastPoint <> p.points, @curRank := @curRank + 1, @curRank) AS rank, IF(@lastPoint = p.points, @curRank := @curRank + 1, @curRank), @lastPoint := p.points FROM player p JOIN (SELECT @curRank := 0, @lastPoint := 0) r ORDER BY p.points DESC ) ranks ON (ranks.playerID = player.playerID) SET player.rank = ranks.rank; When I try to execute this as a native query in Hibernate, the following exception is thrown. java.lang.IllegalArgumentException: org.hibernate.QueryException: Space is not allowed after parameter prefix ':' Apparently this has been an open issue for the last couple of years, I want to know if the ranking query can be made to work either Without using any variables in the SQL query OR Using any workaround for Hibernate.

• Use the Django ORM in a standalone script (again)

  - by Rishabh Manocha

  I'm trying to use the Django ORM in some standalone screen scraping scripts. I know this question has been asked before, but I'm unable to figure out a good solution for my particular problem. I have a Django project with defined models. What I would like to do is use these models and the ORM in my scraping script. My directory structure is something like this: project scrape #scraping scripts ... test.py web django_project settings.py ... #Django files I tried doing the following in project/scrape/test.py: print os.path.join(os.path.abspath('..'), 'web', 'django_project') sys.path.append(os.path.join(os.path.abspath('..'), 'web', 'django_project')) print sys.path print "-------" os.environ['DJANGO_SETTINGS_MODULE'] = 'django_project.settings' #print os.environ from django_project.myapp.models import MyModel print MyModel.objects.count() However, I get an ImportError when I try to run test.py: Traceback (most recent call last): File "test.py", line 12, in <module> from django_project.myapp.models import MyModel ImportError: No module named django_project.myapp.models One solution I found around this problem is to create a symbolic link to ../web/govcheck in the scrape folder: :scrape rmanocha$ ln -s ../web/govcheck ./govcheck With this, I can then run test.py just fine. However, this seems like a hack, and more importantly, is not very portable (I will have to create this symbolic link everywhere I run this code). So, I was wondering if anyone has any better solutions for my problem?

• scraping text from multiple html files into a single csv file

  - by Lulu

  I have just over 1500 html pages (1.html to 1500.html). I have written a code using Beautiful Soup that extracts most of the data I need but "misses" out some of the data within the table. My Input: e.g file 1500.html My Code: #!/usr/bin/env python import glob import codecs from BeautifulSoup import BeautifulSoup with codecs.open('dump2.csv', "w", encoding="utf-8") as csvfile: for file in glob.glob('*html*'): print 'Processing', file soup = BeautifulSoup(open(file).read()) rows = soup.findAll('tr') for tr in rows: cols = tr.findAll('td') #print >> csvfile,"#".join(col.string for col in cols) #print >> csvfile,"#".join(td.find(text=True)) for col in cols: print >> csvfile, col.string print >> csvfile, "===" print >> csvfile, "***" Output: One CSV file, with 1500 lines of text and columns of data. For some reason my code does not pull out all the required data but "misses" some data, e.g the Address1 and Address 2 data at the start of the table do not come out. I modified the code to put in * and === separators, I then use perl to put into a clean csv file, unfortunately I'm not sure how to work my code to get all the data I'm looking for!

• Can't get any speedup from parallelizing Quicksort using Pthreads

  - by Murat Ayfer

  I'm using Pthreads to create a new tread for each partition after the list is split into the right and left halves (less than and greater than the pivot). I do this recursively until I reach the maximum number of allowed threads. When I use printfs to follow what goes on in the program, I clearly see that each thread is doing its delegated work in parallel. However using a single process is always the fastest. As soon as I try to use more threads, the time it takes to finish almost doubles, and keeps increasing with number of threads. I am allowed to use up to 16 processors on the server I am running it on. The algorithm goes like this: Split array into right and left by comparing the elements to the pivot. Start a new thread for the right and left, and wait until the threads join back. If there are more available threads, they can create more recursively. Each thread waits for its children to join. Everything makes sense to me, and sorting works perfectly well, but more threads makes it slow down immensely. I tried setting a minimum number of elements per partition for a thread to be started (e.g. 50000). I tried an approach where when a thread is done, it allows another thread to be started, which leads to hundreds of threads starting and finishing throughout. I think the overhead was way too much. So I got rid of that, and if a thread was done executing, no new thread was created. I got a little more speedup but still a lot slower than a single process. The code I used is below. http://pastebin.com/UaGsjcq2 Does anybody have any clue as to what I could be doing wrong?

  Hi There, I ahave some ajax that is fired when a checkbox is clicked, it essentially sends a query string to a PHP script and then returns the relevant HTML, however, if I select a select it works fine if I then slect another checkbox as well as the previous I get no activity what so ever, not even any errors in firebug, it is very curious, does anyone have any ideas? //Location AJAX //var dataObject = new Object(); var selected = new Array(); //alert(selected); $('#areas input.radio').change(function(){ // will trigger when the checked status changes var checked = $(this).attr("checked"); // will return "checked" or false I think. // Do whatever request you like with the checked status if(checked == true) { //selected.join('&'); selected = $('input:checked').map(function() { return $(this).attr('name')+"="+$(this).val(); }).get(); getQuery = selected.join('&')+"&location_submit=Next"; alert(getQuery); $.ajax({ type:"POST", url:"/search/location", data: getQuery, success:function(data){ //alert(getQuery); //console.log(data); $('body.secEmp').html(data); } }); } else { //do something to remove the content here alert($(this).attr('name')); } });

• sql charateristic function for avg dates

  I have a query which I use to grab specific dates and a price for the date, but now I'd like to use something similar to grab the avg prices for particular days of the week. Here's my current query which works for specific dates to pull from a table called availables: SELECT rooms.name, rooms.roomtype, rooms.id, max(availables.updated_at), MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 0, (availables.price*0.66795805223432), '')) AS day1, MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 1, (availables.price*0.66795805223432), '')) AS day2, MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 2, (availables.price*0.66795805223432), '')) AS day3, MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 3, (availables.price*0.66795805223432), '')) AS day4, MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 4, (availables.price*0.66795805223432), '')) AS day5, MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 5, (availables.price*0.66795805223432), '')) AS day6, MAX(IF(to_days(availables.bookdate) - to_days('2009-12-10') = 6, (availables.price*0.66795805223432), '')) AS day7, MIN(spots) as spots FROM `availables` INNER JOIN rooms ON availables.room_id=rooms.id WHERE rooms.hotel_id = '5064' AND bookdate BETWEEN '2009-12-10' AND DATE_ADD('2009-12-10', INTERVAL 6 DAY) GROUP BY rooms.name ORDER BY rooms.ppl My first stab which doesn't work, probably because the DAYSOFWEEK function is much different from the to_days...

• Query Optimizing Request

  - by mithilatw

  I am very sorry if this question is structured in not a very helpful manner or the question itself is not a very good one! I need to update a MSSQL table call component every 10 minutes based on information from another table call materials_progress I have nearly 60000 records in component and more than 10000 records in materials_progress I wrote an update query to do the job, but it takes longer than 4 minutes to complete execution! Here is the query : UPDATE component SET stage_id = CASE WHEN t.required_quantity <= t.total_received THEN 27 WHEN t.total_ordered < t.total_received THEN 18 ELSE 18 END FROM ( SELECT mp.job_id, mp.line_no, mp.component, l.quantity AS line_quantity, CASE WHEN mp.component_name_id = 2 THEN l.quantity*2 ELSE l.quantity END AS required_quantity, SUM(ordered) AS total_ordered, SUM(received) AS total_received , c.component_id FROM line l LEFT JOIN component c ON c.line_id = l.line_id LEFT JOIN materials_progress mp ON l.job_id = mp.job_id AND l.line_no = mp.line_no AND c.component_name_id = mp.component_name_id WHERE mp.job_id IS NOT NULL AND (mp.cancelled IS NULL OR mp.cancelled = 0) AND (mp.manual_override IS NULL OR mp.manual_override = 0) AND c.stage_id = 18 GROUP BY mp.job_id, mp.line_no, mp.component, l.quantity, mp.component_name_id, component_id ) AS t WHERE component.component_id = t.component_id I am not going to explain the scenario as it too complex.. could somebody please please tell me what makes this query this much expensive and a way to get around it? Thank you very very much in advance!!!
