• With the help of the socket object to retrieve data from web application without the html files

  I tried to use the socket object to retrieve data from a web application (I just control script version vs version online). So all I want to do is access http://hyle.io/version that returns me the current version of the application (such as a simple string) in order to compare it in my script and then notifies the user accordingly. I have just a few problems using the socket object. I used this code from the Adobe Javascript Tools Guide:

  
  

  reply = "";
  conn = new Socket;
  // access Adobe’s home page
  if (conn.open ("www.adobe.com:80")) {
  // send a HTTP GET request
  conn.write ("GET /index.html HTTP/1.0\n\n");
  // and read the server’s reply
  reply = conn.read(999999);
  conn.close();
  }
  

  ... that I then adapted as:

  reply = "";
  conn = new Socket;
  if (conn.open ("hyle.io:80")) {
    conn.write ("GET /version HTTP/1.0\n\n");
    reply = conn.read(999999); 
    conn.close();
  }
  

  And here is what I get:

  HTTP/1.1 400 Bad Request
  Content-Length: 225
  Content-Type: text/html
  Server: Pagodabox-Routing-Mesh
  
  Bad Request
  Your browser sent a request that this server could not understand.
  Résultat : true
  

  I don't know a lot about HTTP requests, but I wondered if it was related to the fact that I am not pointing to a specific HTML file and the type of request was wrong or if I should rather check if there is something wrong with my host?

  The site/app is PHP and is hosted on PagodaBox if it helps.

  Thanks in advance!

  Hi Sebastien Lavoie,

  It should work

  var HTTPFile = function (url, port) {}

  If (arguments.length == 1) {}

  URL = arguments [0];

  port = 80;

  };

  This.url = url;

  This.port = port;

  this.httpPrefix = this.url.match(/http:\/\//);

  This.Domain = this.httpPrefix is nothing? This.URL.Split("/") [0] + ":" + this.port: this .url .split ("/") [2] +":" + this.port;

  This.Call = ' GET ' + (this.httpPrefix == null? ' "). " http://" (+ this.url: this.url) + "HTTP/1.0\r\nHost: ' + (this.httpPrefix is nothing? "This.URL.Split("/ ") [0]: this .url .split (" / ") [2]) +" \r\nConnection: close\r\n\r\n ";

  This.Reply = new String();

  This.Conn = new Socket();

  This.Conn.Encoding = "binary";

  HTTPFile.prototype.getFile = {function (f)}

  var typeMatch = this.url.match(/(\.) (\w{3,4}\b)/g);

  If (this.conn.open (this.domain, "binary")) {}

  This.Conn.Write (this.) Call);

  This.Reply = this.conn.read (9999999999);

  This.Conn.Close ();

  } else {}

  This.Reply = "";

  }

  (Return this.reply.substr(this.reply.indexOf("\r\n\r\n")+4);

  };

  }

  Hyle var = new HTTPFile ("http://hyle.io/version");

  Alert (hyle. GetFile());

  And by the way, I like the idea of 'http://hyle.io'. Can you give me your email address, I want to learn more about this Web site.

  Based on the data, the user ID 39 must be found, since it's been sitting since 09:36-10:35, which is continuous 1 hour.

  Any guidance how to do using SQL query will be of great help and appreciation.

  Thank you very much

  Kind regards

  So what exactly is wrong with the request that I already gave you?

  Just to remind one untested (because of lack of insert statements) rewrite according to your new data:

  with grp as)

  Select

  username

  UserRecognizedActivityID activity

  starttime

  starttime + endetime + 1

  row_number() over (partition by order of starttime userid)

  -ROW_NUMBER() over (partition of userid, UserRecognizedActivityID order of starttime)

  RN

  of activity_log

  )

  Select

  username

  min (starttime) starttime

  max (endtime) endtime

  max (activity) activity

  GRP

  Group userid, rn

  with round (max (endtime) - min (starttime) * 24 * 60) > = 59

• Help required with SQL query

  I have three tables listed below
  
  FORMAT - Columns are format_id, format_desc
  VIDEO_FORMAT - areVIDEO_FORMAT_ID of columns, COST VIDEO_ID, FORMAT_ID,
  RENTAL - Coulmns are RENTAL_ID, DATE_OUT, DATE_DUE, DATE_IN, DELIVERY_STATUS, LATE_FEE, CUSTOMER_ID, VIDEO_FORMAT_ID
  
  I need to find the customer list id, format description and cost of the video format for customers who have rented a video.
  
  I wrote the request
  
  Select rental r format f, video_format, r.customer_id, f.format_desc, vf.cost vf where f.format_id in (select video_format format_id) and r.video_format_id = vf.video_format_id
  
  This isn't to get accurate results. Help, please.

  Would know what kind of results you get, but I think that I can see.

  Try:
  Select r.customer_id, f.format_desc, vf.cost
  rental r, f format, video_format vf
  where vf.format_id = f.format_id
  and r.video_format_id = vf.video_format_id

  Can't be sure without a little more information so that will set you. But I do not know why you went with trying to get a relationship using an IN with a subquery. It will be useful.

  Hi all

  I'm in printing, create the process of mapping driver prerequisite for aid to perform immediate with Create table T1 as a sql query. Petition to the sides of the Insert into T1 Select * from Source_Table in the different database.
  
  Certainly, need to create Db users in the Source database, to get privileges to read the data of source_database.
  Is - this good aproach to or of any other alternative to achieve this.
  
  Means, create the table in the transit area (desired area, where I am) and using driver mapping process before you run the select query to retrieve data from a data source.
  
  Would apreciate your previous answer.

  Specifically, the two simple solutions provided were:

  1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).

  2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))

  4. WHEN r = 1

  2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  You can simulate loops with sql functions as the clause-type (since 10 g) or recursive subquery (since 11.2).
  Generally in this forum link it by the approach will be proposed.
  The depth will be the number of occurrences of your model and the level will be the real occurency.
  So just search inthi forum for an abundance of examples

  select regexp_substr(col2, 'A[0-9]{4}', 1, level)
  from tabel1
  connect by
  level <= regexp_count(col2,'A[0-9]{4}')
  

  regexp_count since 11. ?

• create the http client to retrieve data from web service

  Hello

  I am newbie on our webworks. I need to retrieve data from web service. How to connect to this service and analyzed. There is a tutorial that can help me get started with it.

  Can any one advice me how can I start working with webworks on blackberry 10

  Thanks for any help

  In general, you will need to use an AJAX call to the server

  It really depends on what the server returns as to how the information is easy to digest

  JQuery provides a simple interface, and returns information easy to use

  If you deal with things gets complicated XML according to namespace

  If you look at the raw XML data and it goes something like fred: name you will have questions requiring an implementation of SAX - JSON is simple if you don't get that even if (nothing too confusing here)

  If using an external data source JSON go if you have the choice

  As examples go - just look to the top of JQuery Ajax [JSON / XML] and you will get where you're going quickly

  SAX is MUCH harder because of the namespace - Dublin is the most common and same XML without namespace is not simple to handle, so avoid it if you can

• retrieve data from staging account

  Hello
  
  does anyone know how we can retrieve data from staging of account using 'Segmentation Wizard', "report analysis tool", model of fusion and mailing, etc.?
  
  Seems that these tools connect only to the production instance...
  
  Thanks, Sab

  SAB,

  for segmentation Wizard (and perhaps other office files), you will have to go file - properties - Custom and update the values for the name of pod, if you have a job you know what value it is as I am not "have a practice to watch.

  see you soon

• need help with sql query dates

  Hello
  
  I have a sql query I need to extract some info between data dates. Where clause in this query is:
  
  WHERE CPD_BUS_UNIT =: ESI_PRM_1
  AND CPD_VOUCHER_DATE > =: P_DATE_FROM
  AND CPD_VOUCHER_DATE < (: P_DATE_TO + 1).
  
  When I run the query into a toad, I can view the data, but not the execution plan. It gives an error ORA-00932 inconsistent Datatypes.
  But when I remove (+ 1): P_DATE_TO, I can c the execution plan and data. The data will be different from the previous.
  
  Please suggest how to rewrite the query.

  Can you please give it a try?

  WHERE CPD_BUS_UNIT=:ESI_PRM_1
  AND CPD_VOUCHER_DATE >= :to_date(P_DATE_FROM)
  AND CPD_VOUCHER_DATE < (to_date(:P_DATE_TO)+1)

• Help with SQL Query (Subselects)

  Hello community,
  
  IAM a new Member in this forum. The first excuse my English, my native language is German.
  In my workplace, we have a great Orcle Database 11 g with 30 different tables for production control issues.
  I try to get a couple of different information from the database, so I started with SQL of the query, but for this problem, I wasn't able to write a query to work.
  
  In this case, I have 2 tables:
  Table 1:
  ID; ORDER_NR; DESCRIPTION; CREATE_DATE
  1; A500236; CLEAN HOUSE; 20/02/2012
  2; A623555; REPAIR CAR; 10/01/2012
  3; A866944; MAINTAIN EQUIPMENT; 11/02/2012
  
  Table 2:
  ID; ORDER_NR; WO_STEP; STEP_DATE; EMPLOYEE
  1; A500236; A; 21/02/2012; W0010
  2; A500239; F; 21/02/2012; W0010
  3; A500239; S; 22/02/2012; W0027
  4; A500239; R; 23/02/2012; H0034
  5; A500239; U; 25/02/2012; L0099
  6; A263555; A; 15/01/2012; G0009
  7; A263555; C; 17/01/2012; S0039
  5 V A263555; R; 18/01/2012; K0059
  9; A263555; U; 19/01/2012; A0048
  10; A866944; A; 13/02/2012; H0034
  11; A866944; B; 13/02/2012; L0035
  12; A866944; G; 17/02/2012; D0084
  13; A866944; U; 23/02/2012; S0039
  
  And the result of my query should look like this:
  ORDER_NR; DESCRIPTION; CREATE_DATE; A_STAT_AGE; R_STAT_AGE; U_STAT_AGE
  A500236; OWN HOME; 20/02/2012; 5; 3; 1
  A623555; REPAIR CAR; 01/10/2012; 42; 39; 38
  A866944; MAINTAIN EQUIPMENT; 11/02/2012; 15; 4; 3
  
  The age of my query result should be calculated from the date of the creation of the order.
  I would like to know 2 things, one is how old was the order when they reached this status, R and U.
  The second, that is, how long did you order remaining on A stat, R and U (and if possible all the others too)
  It can happen that not every order reaches every State, so he ca go directly from A you in this case I want to display a generic character in this row/column
  
  I hope you all know what I mean and what result to expect.
  
  Thanks for your help.

  Hi Frank,.

  I thank you for your professional response and excuse my non-professional way to clarify my question.
  I have now already read and understand how to ask good questions, but is there an easy an inexpensive way to run a database on my computer at home?

  You can download the Oracle database from this site. The Express edition is easier to install. It lacks a few features that the Enterprise edition (for example, partitioning table and safety of level line), but most of the things work in all editions of Oracle.
  All editions are free if you do not use them for Production applications. Of course, at this price (or lack thereof), you get Oracle support.

  I have already noticed that the syntax SQL for Oracle differ from other DBMSS.

  Yes and some features are different in different products.

  Your query works perfectly, thank you.

  Now I want to refine my (your) query, is there a way to display a range of day within 1 day? As 0.5 day to half a day between two State timestamp.

  Of course, you can do it. After the exact output desired of the sample data that I posted. If the sample data do not show what you need to do, then after a few different examples of data that makes.

  My table contains the Date and time in a row, I forgot to mention that.

  After a CREATE TABLE statement. I was guessing a lot of things that may be important. For example, I assumed you were using a DATE for date and time column. So it is only reasonable to do so, but maybe it's not what looks like at your table.

  I tried something like this:

  SYSDATE - MIN ( CASE
                      WHEN  t2.wo_step = 'A'
                THEN  t2.step_date
            END
             ) AS Age_A
  

  But it gives me an error of arithmetic overflow and not die difference in the Date and time or days with decimal friction.

  There are only about 5.4 million possible days with DATEs of Oracle. Is only 7 digits and Oracle can treat approximately 39 numbers without overflow errors, so I don't see how this can happen if t2.step_date is really a DATE. This is an example of why you need to publish a CREATE TABLE statement.

• SQL Query to retrieve records for all after the Max Dates.

  Hello everyone,

  I am trying to retrieve the record more recent, based on the date field ( nextDate ).

  Currently, there are only 4 records in the MC_Maintenance table and two in the Machine table.

  Machine table

  MC_id             EquipID          

  1                      0227

  MC_id EquipID

  2                     0228

  ---------------------------------

  MC_Maintenance table

  1                      2                      08/25/2010     

  2                      2                      07/01/2010

  3                      1                      2010-11-06

  4                      1                      07/11/2010

  I have am trying to accomplish is,.

  the list of the two machines of the table of the Machine with the MAX (Next_maint) control the list of MC_Maintenance results

  These are the records I want to display.

  Maint_id MC_id Next_maint

  1                      2                      08/25/2010

  4                      1                      07/11/2010                 

  Here is the SQL query

  SELECT

         MC. MC_ID as ID,

  MC.complete_Date completed.

  MC.next_maint as nextDate,.

  MC.maint_notes as noted,.

  MC.facility Facility.

  M.EquipId,.

  $m.name as the name.

  M.SerialNumber SN.

  M.dept as dept.

  M.Freq as freq

  Of MC_Maintenance MC, Machine M

          where  MC. MC_ID = M.MC_ID

  '           Using MAX (nextDate)

  Any ideas would be useful.

  I thought it was a simple group of problem?

  SELECT M.EquipID, MC.MC_ID, Max(MC.next_maint)
  FROM MC_Maintenance MC INNER JOIN Machine M ON MC.MC_ID = M.MC_ID
  GROUP BY M.EquipID, MC.MC_ID
